Purchase Better Graphics Cards For Computers

They happen to be one of the essential components of a computer, immaterial of whether it is a net book, a laptop or a desktop.

One of the vital factors that should be taken into account before buying a card is the memory capacity. Many ranges of memory capacity for graphics cards are sold in the electronics market. Normally, it starts from 16M to 640M and beyond.

In general, it is advisable to get a card with a memory capacity like 512M if you work with many graphics. There are three main components like a memory chip, a graphics processor and a RAMDAC display output for a card. RAMDAC is the component that changes the image data into a format, which can be shown by the monitor.

In the case of a graphics processor, the speed is crucial for processing images and working with multitudes of images at one go. Therefore, if you have to work with complex images and many intensive graphics, getting a card with a high memory capacity and faster graphics processor would be advisable. For those who love to play 3D video games or watch 3D movies, a 3D one is needed.

For normal use, you can buy a 2D graphics one. The 3D one is much more expensive in comparison to the low cost 2D one. If you possess a desktop personal computer, it would not be difficult to change the graphics card by yourself. Normally, the graphics card will be located in the expansion slot of your desktop.

However, for a portable computer, you need to give it to a computer technician to do so. As you may know, adjusting a portable could cost much money. The wiser thing to do would be to decide on the specifications of the graphics card before purchasing your net book or laptop.

Quality Processors Will Improve Your Computer's Speed

Along with many of the other parts of a computer the most important part that computer users need to know about is the processor. Also called the CPU or Central Processing Unit. This is vital to the understanding of why or how your computer seems slow. In general the CPU can be looked at as the main brain of the computer. It can be related to the human brain and seen as the part of the computer that makes all of the decisions for the actions that the computer does. Of course all of these actions will be commands by you the user.

Well first we will look at one of the most important and talked about parts of the CPU, the speed. Most people brag about how fast their new processors are and that they have the new 3.3Ghz blah blah blah. What does this mean? Well basically it is how many calculations per second the CPU can do. In other words how many cycles per second that the CPU can compute for you. Ghz or gigahertz stands for a billion cycles per second. A 3.3Ghz processor, for example, can do 3.3 billion cycles per second. It holds a direct relationship, the higher the number the faster the processor. The computer industry is still seeing no slowing trend or stop and we will continue to see these numbers rise and rise as the technology gets faster and faster.

Another important part to understand about the CPU, that also directly affects our computers speed, is the cache. This is vital for you to keep from having a slow computer. Without a high cache your processor will have limited performance. This means your computer will start to struggle when it has a high demand placed on it. Cache is basically memory set aside for the CPU to use for "short term storage". When a CPU is processing something and needs to gather information it will use this memory to allow for the major processes to start. The more short term storage or cache that is set aside for this the easier it will be for the CPU. Again we see a direct relationship the higher the cache memory the better performance. Those are the main things that we need to understand in a CPU that can either make our computer running really good and efficient or that can completely make using our computer frustrating.

Do You Have Real Ink?

Ink for my Canon MX310 runs around 24 bucks for 13 mL of ink. A little math reveals that each mL costs around 1.80, or an astounding $1,800/liter.

Printer manufacturers depend on their ink sales, in a business model usually referred to as captive-product pricing (like replacement blades for mens' razors). Because they make so little off the sale of a printer, companies like Samsung, Kodak and Canon recoup their margins in the sale of ink.

Something that nets good margins as a branded name can also product positive margins for a faker. Not unlike other counterfeit products like iPods or Cartier watches, fake printer ink cartridges are making an appearance.

Unlike the mistake of buying a Cartier that turns out to bogus, however, these ink cartridges' damage is not finished after you buy them. They are still prone to leaking, falling apart, exploding, smudging paper and jamming the print heads. This often puts consumers out of not only the cost of the fake ink cartridges, but the cost of a new printer after their old one is ruined.

The fake ink cartridges are generally produced en masse in cheap facilities in China, Malaysia or the Philippines, then shipped to the Americas for distribution to discount-hungry consumers. Next, unwitting midsize ink distributors purchase them and redistribute them to end consumers or small distributors. They use midsize ink distributors because they're too large to trace any individual cartridges and too small to have top-notch buying and processing standards to catch the counterfeits.

Relatively infrequent in the United States, authorities in Latin and South America estimate that current counterfeit ink cartridge penetration on the market is around 50%. The values in the US are more along the lines of 5%.

The best way to counteract this problem and eliminate your risk of a counterfeit cartridge is probably to buy from a reputable third-party distributor. They generally are selling recycled manufacturer ink cartridges that have been refilled anyway. Because they sell at a discount over the manufacturer prices, no one is bothering to make counterfeit recycled cartridges (at least not yet, anyway).

You should also check the packaging and cartridge carefully for any misprints or imperfections, especially if you got the ink at a significant discount.

Removing the Skeletons From Your Server Closet

Your server is an important part of your business. Your server equipment should be secure, safe and efficient to protect your vital business information over the long term, but it's also just as important to keep up the maintenance on your server room as well.

Let's look at some things you can do to organize your server room.

Organization

If your server room is disorganized, then imagine sliding out one server only to find another fall out on top of you. Adequate shelving for each individual server means easier access for hardware maintenance and less risk of potential equipment damage or personal injury.

Some businesses add hardware to their original servers over time, but don't plan for adequate server racks. As you add new hardware, be sure to add or modify existing shelving so that each server has its own slides or shelving.

Air Flow

When you're organizing your server room's shelving and racks, be sure you set up your room's layout to maximise airflow through the room and around your equipment. This will help prevent internal server cooling systems from overheating.

Untangling any Server Issues

Your server room will contain a lot of cables, cords, expensive equipment. While most server rooms will have cords neatly tucked away to avoid damage or potential injury, there are those with jumbles of cords stretched everywhere.

Take some time to untangle Ethernet cables, KVM cords, power cords, network cables, and any other wiring. Use clips or tiebacks to keep cables and cords neat and in order.

Power Play

It's important to evaluate your power outlets and how you're utilising them. Having a server room with only one power outlet, but hooked into multiple adapters and power boards may not only be a hazard to your equipment, it may also become a fire hazard.

Evaluate our power boards and power strips. Have extra power outlets installed if you feel you require more outlets. Always be sure you keep up to date with any power technology and maintain your server room's power needs.

Temperature

Servers tend to give off heat, which can heat up your server room quickly. More importantly, some servers can have a tendency to overheat if adequate cooling systems aren't in place to regulate the temperatures.

For the safety of your equipment and protection of your server room environment, make sure to install sufficient cooling systems to meet your requirements. If you live in an area where humidity is a factor, be sure to include humidity monitors and even humidifiers to help control the levels of moisture in your server room.

Unnecessary Server Room Items

While most businesses keep their server equipment in a dedicated server room, some businesses store a multitude of other items in a server room as well. The security of your servers and the information stored on them should be a priority, so storing unnecessary items alongside server equipment may become a hazard.

Servers can overheat and be easily damaged if adequate airflow and ventilation is blocked by close proximity to items that shouldn't be in a server room in the first place.

Remove any boxes, files or other accumulated business items you've decided to store in your server closet and make sure your equipment is uncluttered.

Why Choose a Desktop Computer

Slick computer ads bombard us from almost every magazine and television station we see. Many of these ads are peddling laptop computers. Are laptops the wave of the future, or are there still good reasons to choose a desktop? This article will cover some of the benefits of desktop computers.

Price

Desktop computers are much more affordable than laptops. You also get a lot more computer for your money. You can get a basic computer for just a few hundred dollars. A blazing fast, powerful gaming computer will cost a fraction of what it would if you chose a laptop.

Upgrades and Repairs

You can easily upgrade and customize a desktop computer. If you want to get a wide screen monitor, you just buy the new monitor and plug it in. You can even easily add dual screens to your computer. The same goes for your mouse and keyboard - when you want a new one, you just purchase the model you'd like, bring it home, and plug it in.

You can quickly and easily add many different options to your desktop, including speakers, printer, and other peripherals.

If you'd like to upgrade RAM or add a second hard drive you can generally do so pretty easily. Graphics cards and other system components can also be upgraded. It's much, much harder to perform such upgrades with a laptop computer.

Repairs on desktops are generally simpler - and less costly, as well.

Security

Though the inherent security of your desktop is probably not greater than the security of your laptop, there are some security advantages granted just because your computer is stationary.

You're not going to accidentally leave your computer somewhere... nor is anyone going to try and snatch it away from you. It's less likely to be around unauthorized users who may try to access your stored files and information.

In the event that your home is broken into, your desktop is not as likely to be stolen as a laptop would be.

On a related note: because your computer is moved less often, it's much less likely to get dropped and broken!

Good Design

The design of desktop computers has stood the test of time. They're built solidly and manufacturers know the proper place to put ventilation holes. This allows your computer to stay cool and functional for you. Even if you put your computer under your desk, it will most likely be able to vent properly. Plus, you can easily vacuum out your desktop vents.

A laptop is a constantly evolving experiment in design, and even some of the newer models have very poor vent designs. They may look good on paper, but in real life, they don't work well and the computers overheat. This is a surprisingly common laptop flaw that can cause loss of data and corruption of your operating system.

This basic overview highlights just some of the advantages of a desktop computer over a notebook. If your computer does not need to travel with you, I highly recommend you get a good desktop. Choose one with the features you need, and look for a model that will allow for upgrade. This will give you the most value and the longest use from your purchase.

Save Space in Your Server Room - Install Rackmount Keyboards

Are you running out of space in your server room? Is there not enough space to install a regular keyboard in front of the monitors? There's nothing to worry about. Pick up some good rackmount keyboards to install in the server room. Compact yet fully functional, these keyboards will help you utilize the space left in your server room more efficiently.

However, before you invest in a rackmount keyboard, it is important to look out for a few factors, which will ensure that you will be using your keyboard in a hassle-free manner for a long time to come. Here are the key points:

1.Check the dimensions: Rackmount keyboards come in various dimensions, so make sure you are getting the right one to fit into the space left in your server rack. Better yet, measure the remaining space in your server rack beforehand. Make note of the dimensions, including the depth. That way, you will be able to buy the perfect keyboard for your server room.

2.Look out for proper build: Rackmount keyboards will be shielded from most kinds of physical impacts after those are installed. But that does not mean the construction can be flimsy. The keyboard should be sturdy enough to last at least a few years.

3.Check the sensitivity of the keys: In a server room, you may have to type while standing in a confined space. So, make sure that the keys on the keyboard are responsive enough to ensure stress-free typing. Also, prefer keyboards that have soft touch keys.

4.Get one with trackball (preferably): Ask the dealer whether he has a keyboard with a built-in trackball. This will save time and reduce stress considerably for you, especially if there is not enough space in your server rack to install a mouse.

5.Watch out for deals: Rackmount keyboards are typically quite expensive. But that does not mean you have to fork out a considerable amount every time. Many shops provide deals on these keyboards from time to time. Look out for these offers, and pick one up if you think the price is suitable.

Always search on the internet for deals on rackmount keyboards before you go to buy one. You may come across some great offers.

Put Away That Expensive CD and DVD - Use A Virtual Drive

Use of a virtual drive will save your original media from accidental damage.

In the computing world there are a lot of 'virtual' devices. Virtual Drives emulate a physical drive; it could be a CD ROM or DVD. You make a copy of the CD or DVD store it on your hard drive and when you need it you 'mount' the copy or image of the original instead of putting the disk in a physical drive. The emulator is not limited to the speed that a physical CD or DVD drive, it has the same speed as the hard drive it is stored on. Although for a network share the limiting factor will be the speed of the network that the computer is connected to.

There is a problem with some programs though; the publishers of Games have software on the disk that prevents either coping or verification of the disk. This means that if you have a game on a cd and the cd is required to start the program then using an image will not work. There are different schemes for securing the cd from hidden tracks to hidden keys for the program to read when it starts.

For normal programs that you have that are of high value or that your business installs on a regular basis a Virtual Drive program would be very useful. With the program you could make an image of the program disk, store it on a server and then mount the disk and share the virtual drive for access to those individuals that do you installs.

Another use for a Virtual Drive is for experimentation. You could lay out your cd or dvd and make an image of the data to see if it will work with out burning an actual disk. With the price of disks these days that may seem to be a bit too frugal but consider the time factor and if it isn't the way you want it to be or you want to add more to the disk then deleting an image does make economic sense.

How does it work? There are a lot of different programs that do CD or DVD emulation, one of them is called Daemon Tools, another is called FarStone Virtual CD. Both are excellent programs that will create and mount a cd or a dvd. The first step is to create the image. Then you mount it or insert it in the emulation. Then you would use it the same as any other media. You could take a list of unrelated directories and make an image such as for a custom computer install, instead of having four or five cd's with the installation files create one image with all the installation files. Then mount the image and share it across a network making the configuration of multiple computers at one time possible with out handing out separate sets of media to each technician doing computer installs.

If you are a 'road warrior' and fly a lot you could make images of your favorite audio cd's or make images of movies, mount it while you are in flight and you have a movie or your favorite music. You are not limited to just programs when you make an image, you can make images of an Audio or video cd or dvd. The possibilities are limitless.

Data centre and computer room cooling is one of the most involved tasks of data centre management. You need to fully grasp the range of options open to you, to put in place the right cooling equipment and monitoring systems. Your key steers will be the rack power density in your IT equipment and your facilities' efficiency levels.

These are the three issues you'll need to factor in to manage data centre cooling:

Cooling data centres
Understand your IT equipment power density needs, then follow this up by defining a solution that suits your current IT equipment, but importantly, gives room for flexibility and scalability in the future.

It's acknowledged that cooling is the biggest power consumer in data centre M&E operations and in many legacy operations, it can use more than the actual IT equipment. So it's essential to pick the correct solution as it will greatly influence whether you can make improved energy efficiency levels in your centre. This will in turn impact favourably on your centre's operational costs.

Integral to sustaining the right environmental conditions, identifying and managing hotspots and achieving efficiency, is to need to fully grasp and control airflow in your technical space. This involves considering the cool air supply levels, server heat load and heat rejection as interrelated and not separate systems.

Understanding data centre cooling technology is a key component to managing your room temperatures. To master this demanding challenge, you'll need to fully understand key concepts such as computational fluid dynamics (CFD) modelling, Power Usage Effectiveness (PUE) and Data Centre infrastructure Efficiency (DCiE) Assessment.

KVM Switch - Reduce Investment in Peripherals by Controlling Multiple Computers With Single KVM

Multiple computers may be controlled with a single set of peripheral devices. This is possible using a KVM Switch. Saving space and ensuring better management of cables, these switches are a boon in places where there is a shortage of space. Supporting multiple platforms like SUN, IBM, HP, Dell, Windows Vista/2003/XP/2000, UNIX and MAC, these switches allow the network personnel to access, control & manage the company's servers even when the corporate network is non-functional. They are vital in improving productivity & overall server management by allowing Out-Of-Band access to the company's servers and IT devices. Available in many shapes, sizes and designs, these devices support both USB as well as PS2 peripheral devices.

The switch supporting PS2 devices is known as a PS2 KVM Switch. These switches come in 2, 4, 8 and 16 port versions. Being hot pluggable, these units allow control to be switched between systems via hot keys, on screen display as well as push buttons in front of the unit. Some models are also available with optional audio and include the ability to switch audio from each PC that is connected and transmit the sound to a set of peripheral speakers. Available in rack mount versions, the Dual Video PS2 Switch help to control multiple computers with dual video connections. With advanced technology, the newer versions of these switches have the benefit of increased distance between the computers and peripherals by using Cat5 cables for the connections.

A Switch which secures connections via category cables is known as a CAT5 KVM Switch. It allows access to servers up to 40 meters. Typically, you can connect from 2 to 32 computers, but by daisy chaining these switches access can be increased up to 256 Servers. Providing VGA video resolution up to 1600 x 1200, the KVM over Cat5 switch is available in 16 or 32 port configurations in 1U of rack mount space. Main features of this device are: multi lingual on screen display menu (OSD), advanced user profiles and configurable OSD hot key combinations, dual power with fail over, 12, 24 and 48 volt DC power options.

In situations where multiple computers are involved, a KVM Switch may be used since it frees valuable physical space and decrease demand on power.

The Functionality of a Proxy Server

A proxy server acts as an intermediary between a web server and the client computer. They track all traffic existing between the internet and the intranet.

These servers can perform all-important functions such as tracking IP addresses, URLs, time and date of access, and number of bytes downloaded. All of this information can be very essential when analyzing any kind of attack against a network. With the help of proxy servers, Intranet administrators can establish better access and provide better services to their employees.

Whenever a computer on the intranet requests the Internet to retrieve certain information or a web page from the web server, the internal computer makes a contact with the proxy server. It then connects to the Internet server, which in turn caters the desired web page to the proxy. The proxy then passes this information or web page back to the computer on the Intranet.

Some proxy servers require the use of certain specific proxy clients. Many people follow the popular approach of using off-the-rack clients with servers. However, while using such a client, it is essential to ensure that the proxy client is specially configured to operate from a configuration menu and in association with servers.

Proxy servers can also be used to implement security schemes. For instance, an FTP (File Transfer Protocol) server can allow the required files to be sent to the computer on the Intranet from the Internet. It can also block the transmission of files from the Internet to the corporate network, and vice-versa. This way, the Intranet administrators can block any unwanted person (outside the corporation) from obtaining crucial corporate data.

Many businesses also use proxy-servers to accelerate the performance of certain Internet services by stashing data-keeping copies of the desired data. For instance, a web proxy server can stash many web pages. Thus, if any person from the Intranet wishes to obtain one of the stashed web pages, he/she can easily obtain it from the proxy server across high-speed lines of the Intranet, rather than going out across the Internet and obtaining the web page at a lesser speed from the Internet lines.

These are some of the ways in which the proxy servers work to benefit the administrators

4 Tips For Organizing Your Server Room

Looking to organize your server room? There are a few things to keep in mind. Since it houses valuable information, safety and security of your equipment should a top concern. The equipment should also be safe and good for long-term use.

1. Choose an Appropriate Rack Size

As you begin designing your computer room, the logical place to start is the server racks. Make sure they have not only enough internal space to house all your current equipment, but your possible future equipment as well. Extra space is a necessity if you ever plan to expand, as you surely will. Also make sure you have enough room to move your servers in and out, as well as enough space to maneuver the equipment around. There must also be enough room between the equipment for safety purposes. When installing equipment, be sure and follow the included instructions so that there won't be any future problems.

2. Make the New Room Part of Your Security Strategy

One of the most important things a business can consider is security. As you plan your server room, make sure you add any changes or additions to your business security strategy. Perhaps you could consider buying server racks with locking doors. You may also consider minimizing personnel access to the room and using cameras or other security monitoring devices to keep an eye on the room at all times. There are many other situations that can potentially cause damage to your server room: temperature changes, water leaks, electrical issues, etc. Adding additional security features to your room will enable you to act quickly to resolve these issues and protect your valuable equipment.

3. Research New Power Technology

Power technology is constantly being improved, providing you with various choices to supply your servers. There are several options to consider: rack mount power strips, remote power products, three-phase power technology, and standard power strips. Your final choice will depend on multiple factors: space in your computer room, number of needed outlets, each plug's requirements, and any redundancy requirements you may be choosing to also implement.

4. Ensure Safety with a Good Cooling Strategy

Each unit gives off a varied amount of heat, making the cooling demands of your computer room also vary. When making the selection, you must evaluate your total requirements together with the available cooling methods in order to ensure the overall safety of the equipment, environment, and personnel.

How to Choose a Scanner

Today's scanners are so powerful and capable that even professional-quality instruments are within reach of anybody who can afford a digital camera or computer.

Flat-bed scanners
Flat-bed scanners are somewhat like photocopiers - you place an original face down on the glass and a sensor runs the length of the original to make the scan. If your print is large enough and good enough, even inexpensive scanners are capable of producing results that can, with a little work, be turned into publication-quality images. These scanners can also be used as a type of close-up camera for taking images of flat subjects at full-size or high magnification.

Flat-bed scanners can be adapted for transparent originals using a transparency adaptor, which is usually another light source that resides in the lid above the scanner bed that moves in step with the scanner head under the original. Check that the adaptor is supplied with the scanner, as a separate one can add considerably to the total cost.

If you intend to scan flat originals of about A4 size, an entry-level scanner offering resolutions in the region of 600 ppi (points per inch) - often quoted as 600 dpi (dots per inch) - will be fine.

For scanning artwork up to A3, you will need an A3-size scanner, which is far more costly than an A4 type. Scanning a large original in sections in order to blend the parts together is not recommended with entry-level machines, as unevenness around the edges is likely to make a poor match.

Well-known manufacturers, such as Umax, Microtek, and Heidelberg, offer machines that cater for a range of needs, from the home-office worker upward. In general, it is true that the more you pay the better performance you can expect in terms both of its mechanical operation and the software interface.

Before you buy
- Examine the interface - the software with which you control the scanner - as some examples can be confusing and badly laid out.
- Check that the scanner's connection is suitable for your particular computer: the best is FireWire (which is also known as IEEE 1394); USB is a low-cost option; while SCSI may be used by some professional-grade equipment.
- Make sure that you can return the scanner to the store if it does not work with your computer and software. Operating conflicts are not uncommon.
- If you need to scan films or transparencies, ask whether a transparency adaptor is extra. If so, check on how much it costs.

How to Reduce Power Consumption in Data Center Operations

For most businesses, the simplest methods for eliminating a problem often go unnoticed. With emerging technologies taxing IT infrastructures and deployment, older technologies are often not taken into account when pursuing a solution. Power consumption can fall into this category as a simple, yet overlooked area of improvement.

The fact is, "energy conservation" has become an industry phrase and there are some very simple, easy-to-implement strategies that can result in instant savings for any business. None of these methods relies on any new technology introductions. Here are five simple strategies for reducing power consumption in the data center.

1. Hot aisle/Cold aisle If your computer equipment in the data center is not properly configured in a hot aisle/cold aisle layout, it should be. This layout of the machinery promotes proper flow of hot and cold air resulting in less work required by the HVAC cooling system and the computer equipment. In virtually all layouts, server racks are set up facing each other in pairs, with the back of one server facing the back of another server in the next pair of server racks in the data center. Data center computer equipment is constructed to bring in cool air at the front of the machine and expel the heated air out the back of the machine. Setting up the racks facing each other in pairs promotes the flow of cooler air at the front of both server racks and the flow of warmer air between the rear of two server racks, resulting in alternating "cold" aisles and "hot" aisles. Note: All data centers use similar principles in rack layout, yet some vary in degrees of exactly where computer room air conditioning (CRAC) units are located. To maximize the flow of heated air to HVAC return ducts, the servers should be placed at 90-degree angles to the CRAC units. Placing the machinery in this manner allows the warmer air to flow unobstructed to the return ducts. Be sure to not force warm air from the hot aisle to travel over cold aisles, as this will result in heating the cold aisles. Also, note there is technology available to simulate airflow into and out of data centers that can be used prior to actually installing your equipment. The hot aisle/cold aisle layout takes advantage of the properties of the cooler and warmer air to reduce work required by other mechanisms that rely on power consumption to get the job done. Any time warm and cold air is allowed to intermingle, more work is required by power-consuming CRAC units and internal computer cooling mechanisms. Computer equipment not designed to take in cool air from the front and expel it at the rear should be placed away from racks that do promote the airflow inherent in a hot aisle/cold aisle layout. These noncompliant devices should be set up in a way that directs warm air exhaust toward a hot aisle, or they should be placed in cabinets capable of redirecting top or side-ventilated exhaust to the rear of the rack.

2. Proper temperature and humidity Setting the correct temperature and humidity levels in the data center is essential to proper airflow in the room. Too often there is a misconception that server rooms should be cold and little monitoring is done to maintain optimum temperature and humidity levels. Many times the only sensor device in the room is the one located on the thermostat. Server rooms should be kept cool, but actually do not need to be cooler than average room temperature throughout the site. The recommended temperature range for data center rooms has always been between 67 and 72 degrees. Too often, businesses cool their data centers down to 65 degrees. It's okay to keep the room a few degrees warmer; the computer equipment will still be operating within recommended and optimal temperature ranges.

Know this: A reduction of 4% in data center power consumption can be expected for each degree warmer the temperature is kept. Of course, equipment must be kept within acceptable temperature ranges and never over 75 degrees, even though hardware specifications may rate the equipment to operate at temperatures of up to 95 degrees. Machinery operating outside of the acceptable temperature range wears down more quickly and poses a risk of overheating resulting in possible downtime. An additional problem is created when keeping a server room cooler than surrounding rooms: increased humidity levels.

The recommended humidity levels for the data center are between 45% and 55%. Cooling air too much can increase humidity over acceptable levels. Once this happens, condensation can gather within sensitive, essential computer equipment and result in a hardware failure. Without the proper sensors in place to detect the temperature and humidity throughout the data center, none of these air properties can be monitored. These should be placed throughout the room to ensure all equipment is operating within acceptable temperature and humidity ranges. Also, know there is a significant difference between conventional air conditioners and CRAC units. Expect reduced power consumption and more longevity with a CRAC unit installed.

3. Proper floor tiles The cold aisle should contain perforated tiles or grates to promote the flow of cooler air from the floor up to the server air intake. Placing these perforations, thus raising the floor within the cold aisle, takes advantage of the inherent properties of cooler air that will reduce the work required by the HVAC system and computer cooling mechanisms. Hot aisles should not contain these floor perforations so that the flow of warmer air to the air conditioning return ducts remains unobstructed. Any time machinery is moved around in the data center, the alternating grates in the cold aisles must also be moved to keep the free flow of warmer and cooler air at a maximum.

4. Bypass air Bypass air is any conditioned air in the data center that is not used by the computer equipment air intakes. This results in airflow inefficiencies within the layout of the data center. Cooler air is promoted to rise from the floor through the use of perforated floor tiles or grates in the cold aisle. Air should be prevented from rising from the floor for any other purpose. Bypass air often results from anomalies in the floor within the data center. These can be holes cut in the floor to permit electrical or network cables leaving the room or broken floor tiles. Look for these areas on the server floor and if possible, seal them to keep bypass air to a minimum. Anytime computer equipment is relocated in the room, be sure to check for any defects on the newly exposed floor and repair it. Also look for bypass air at the cutouts on the rear of server cabinets. Anytime cabling exits the rear of the server, the cutout must be properly sealed to prevent bypass air. Another area where bypass air can occur is around the door to the data center. Ensure that this entryway is properly sealed.

5. Blanking panels Finally, within the hot aisle/cold aisle configuration, blanking panels should be placed in server racks where there is no machinery. If blank spaces are left in the server racks, these gaps will allow hot air from the exhaust to re-enter the cold aisle, reducing the efficiency of the whole configuration. These panels simply cover up the holes at the front of the racks to block the mixing of hot and cold air. This simple fix maximizes the energy-saving potential of your hot aisle/cold aisle data center layout.

Five key questions to ask yourself:

1. Has reduction of power consumption in the data center been overlooked as a way to cut costs? Too often a data center has grown with the business and so has its power requirements. Power consumption in the data center needs to be optimized.

2. Is the data center laid out in the proper hot aisle/cold aisle configuration? Computer equipment in many facilities is placed in rows with the front of one rack facing the rear of another. This is an inefficient layout that increases the power-consuming work of both the HVAC system and the internal computer cooling mechanisms.

3. Is the temperature in the data center at the low end of the acceptable operating range of data center equipment? A common misconception is that server rooms should be cold. The truth is that data centers should be slightly warm and humid, but not too humid.

4. Is there any air entering the room prohibiting the natural airflow of the hot aisle/cold aisle configuration? Any holes around electrical conduits or cabling on the racks themselves need to be sealed to ensure free, maximized airflow.

5. Are enough blanking panels in place that prevent warmer air from mixing with cooler air? Blanking panels are simple, inexpensive devices that prevent warm and cool air from mixing. Implementing these simple power-consumption deterrents in the data center will result in an immediate cost savings. This savings is considerable for any business and these solutions are attainable at very low costs. The only equipment that requires purchasing is the air monitoring sensors and blanking panels, and both of these devices are very inexpensive.

Energy costs are slated to continue rising for the foreseeable future. Power grids are operating at maximum capacity and environmental concerns are preventing the future construction of power plants. Attaining optimized power efficiency within your business is essential to cutting unnecessary costs associated with data center power consumption. Optimization is key throughout your data center, so don't lose out by overlooking the obvious.

Installation Tips For Rack Mount Shelves, As Innovations Dominate Market

Since the inception of the rack mount shelf, computer servers and the associated clutter have magically diminished. But these are not the only advantages that such frames and cases offer. Recent news suggests that with a number of firms investing in innovation and upgrades, the true potential of such frames have been tapped well. Control over excessive heat and power consumption metrics have also been added to their long list of benefits.

With rack mount shelves facilitating ease of use and other important benefits, they have found acceptance across varied platforms. These include storing computer servers, audio equipment, communication kits and other sensitive but complex electronic ensembles. However, even if you have taken utmost care in selecting the dealer and the ideal frame, installing the same can be tricky. From allowing the equipment to function to its full potential to facilitating a cleaner work area, correct techniques of installation can help immensely in the long run.

Here are a few tips to get the installation bit straight:

* Requirements to Be Considered First - Keeping only the rack mount shelf configurations in mind will not help you much. You need to understand that electronic equipment and allied industries undergo regular upgrades. Hence keep space and features available if you wish to incorporate add-ons in the near future.

* Should Complement the Work Area - Installing a rack mount shelf that juts out like a sore thumb and hinders the smooth flow of work is commonplace. To avoid this, make sure you have the whole floor-plan of the work area in mind. Install the equipment in such an area that neither obstructs work, nor makes it hard for people to access.

* Hire Professional Help - Never try and install a rack mount shelf on your own. Either hire professional assistance or consult experts before installing one. Remember that even a loose screw can bring your costly equipment crashing down!

Cheap Printer Ink Cartridges

Printers have become a daily utility instrument and are commonly seen in homes, offices, hotels, restaurants, and many other places. The two basic requirements for any printer to function are electricity and an ink cartridge. A printer cannot function without either one of them. The ink in the cartridge is in limited supply and is consumed quickly. If the printer is not used for a period of time, the ink may dry up and cause the printer to malfunction.

The ink used in a particular printer is not appropriate for use in all printers. Different varieties of ink are broadly classified into dry and wet ink. Ink used in laser printers is toner, which is a dry power-type substance. The ink used in other printers, such as the desk jet series, is liquid ink.

The ink, whether dry or wet, is stored in a cartridge that is placed in the printer. The cartridges are made in such a manner that refilling them is an easy task. However, this needs to be done professionally or the cartridge will cease to function. The printer ink cartridge industry has seen a great demand in refilling of cartridges as this works out as a cheaper alternative compared to buying a new cartridge. They are an efficient and economical alternative to purchasing new ink cartridges. Cheap printer ink cartridges are usually remanufactured printer cartridges that consistently provide high standards of prints with greater efficiency while delivering clear and crisp images.

The quality of ink provided in a ?cheap? ink cartridge is as good as that of a new, regular ink cartridge. Companies selling these ink cartridges guarantee reliable performance with every print and suggest that the use of these ink cartridges will not hamper the printer's warranty.

1 Major Advantage to Wireless Computer Speakers

Wireless speakers are the ideal solution to extending your computers sound capabilities without the need for more bulky and messy cables. Wireless speakers work by sending the audio signal through the air rather than along a cable. This approach has a number of advantages as well as a number of disadvantages.

Advantages

1. No need for extra cables. The clue is in the name, wireless computer speakers don't use wires, so no more snaking cables across the dining room.

Disadvantages

1. Limited range can be a problem. Anything further than the length of a big room could be a problem for some systems and could cause bad sound quality or cutting out.

2. Receivers and transmitters will both need some form of power whether it be batteries or mains adapter.

The advantage of a no wire computer sound system seems ideal at first but you should be aware that some systems claiming to be wireless actually do require a certain amount of cabling. It is important to check before you buy.

Although the list of disadvantages seems to be bigger than the advantages the fact that you will not need cabling is a major advantage and could mean the difference between drilling holes to hide and route cables and just placing a speaker on a shelf without any work whatsoever.

What to look for in your wireless computer speakers

1. Look for a reputable manufacturer. Find reviews on the internet and check what everybody else is saying. The internet is your friend when you are about to buy a new product.

2. Check which speakers are wired and which are wireless. Most wireless systems have some wiring involved. You may decide that wired front speakers and wireless back speakers are the way to go, this will save you money and will mean less power supplies.

3. How is the system powered? Battery power may be fine for a while but batteries run down and your computer speaker system will suffer. The sound quality will gradually get worse as the batteries run down. Much better to go for a mains powered system. The disadvantage of this is that you will need a supply socket near one of the rear speakers and a cable between the two.

There doesn't seem to be a truly completely wireless computer speaker system but modern wireless speaker systems are pretty good at saving the amount of cabling.

The best way to guarantee you find a good system is to search the net for information.

What To Look For In Laptop Comparisons

It is a good idea to know a little about how a computer works, and what you'll be using the system for when buying a laptop or you might get ripped off. You should know the prices of the parts that make up the laptop you are buying. The value of items like processor speed, memory size, hard drive size, graphics card size and software programs will vary from one laptop to another; depending on the brand name and where you are buying from. Here are a few key points and examples that should make laptop comparisons easier, and more useful for you.

Before you buy a laptop you should always know what is inside and make sure that it's not overpriced for the hardware it offers. For example: you can order a gaming laptop right now that will play any game on the market without any degradation in performance, but you can also buy a basic laptop that may look different but has the same exact hardware inside for thousands less. The main problem a lot of people have when buying a laptop is paying for a name. Just because a laptop has a certain brand name on it doesn't mean that the extra money they will be spending will make the laptop itself any better.

You should also be aware of the operating system the laptop runs on and how well it works compared to others for what you'll be using the system for most. Some people prefer Macbook's OSX operating system to Windows, and if your primary use of the laptop will be multimedia based Macbook's OSX may indeed be the better option. However, which operating system to use is often more of a financial issue, or opinion based preference than it is a performance question; and if you'll be using the laptop for work the decision may not even be up to you as you may be forced to use a specific operating system that matches what your company uses.

The most important thing to remember when comparing laptops is that if one has the exact same hardware in it as another and costs a few hundred more, the higher price tag is usually based strictly upon brand name. However, if the systems you're considering cost about the same then you should determine which has the best tech support and warranty options. Laptop comparisons are fairly simple if you know what to look for.

AMD Motherboards

A motherboard is the most important central component of a PC (Personal Computer). It is a printed circuit board (PCB) and is the main connector to the other crucial components of a system. It is also referred to as a main board or system board and is known as the logic board in case of Apple computers. It is casually called the mobo. The components attached to the motherboard that are of significance for the normal running of the PC are the Basic Input/Output System (BIOS), the memory, the Central Processing Unit (CPU), the graphics card, sound card, hard drives, disk drives and other external ports and peripherals.

There is not one, but many mobos in the market to choose from. It depends on the system specifications that you choose to make a decision to buy a particular motherboard. Different motherboards supoort different components so it is important to make the right choice in the type of mobo you buy for your system. Two of the largest manufacturers of CPU today are Advanced Micro Devices (AMD) and Intel. One cannot buy motherboards that supports both. It can only support either one of them due to the difference in the connectors. Both AMD and Intel have the same caliber of performance when it comes to running similar applications, but there are differences in prices and performance depending on the type you choose.

AMD which is a leading global provider of innovative microprocessor and graphics solutions and when it comes to processor architecture, AMD outsmarts Intel. AMD motherboards are largely viewed as more powerful and accommodating than those produced by Intel. While AMD has, until now focused majorly on the business market, it is looking to offer less complicated, stripped down motherboards with few features to target the home computing and gaming market. It also popular amongst game and graphic designers for its extremely large motherboard designs that can easily incorporate large quantities of RAM and several graphics card at a time. There are instances where it can store more RAM than that the current operating system would allow and can run several graphic cards and 2 CPU's simultaneously. However, most of the motherboards are designed to fit into the budget of almost all computer manufacturers. They can only be used with AMD CPU's, a promotional tactic to sell more of their CPU's. Some times the motherboard price is discounted and might even be sold at a loss to encourage the sale of the AMD CPU which is the actual moneymaker.

When purchasing the motherboard make sure you do a thorough research on the motherboard manufacturing site and read about all its product specifications before you shortlist the one you need.

Can I Share the Printers With Other Residents?

Now that you have installed computers in every room in your home, office or building, you should probably have thought of setting up a printer for each computer. Having a printer for each computer terminal in any workspace could well be as impractical as it is expensive. It would be far more sensible if a printer is stationed in a room or row of computers. Since the running cost of printers is something that can easily mount up over time, then wiring up a printer to a number of computer units by way of a network (wireless or otherwise) sounds a good way to go.

Similar to internet connection, printing utilities may also be shared in a network of computers. With a home computer network, residents can share broadband to facilitate convenient file sharing. This system is equally useful to sharing printers. Say, you have more than one printer for different purposes, like laser printers for text and inkjet printers for photos; you can arrange a setup in which all the computers in the room or office will have access to all printers. To do that, there are certain requirements that must be met.

If you wanted to setup a network to allow all your computers to gain access to your printers, you need to have a home network, printer units and print server if your printer is network-capable. In creating a home network, some chooses to create a workgroup, which basically is a local system of connection in which all the computers in your home or office are connected to one another. You may either use your Windows operating system setup or a network setup program disk in completing this step. Creating a workgroup, enables your computer to begin conveniently sharing files within the network.

Network printer application requires a print server. The print server will be responsible in managing the documents to be printed, which is transmitted via the network cable. In networking terms, the print server is a program that arbitrates the print data from a multiple computer units to the specified printer unit.

To connect the printer to the network, you can physically connect it to the main computer or the computer that actually runs the network operating system. All print jobs will be submitted by from the computer to the print server software on the network's file server. The printer must be located near the fileserver. This kind of setup is commonly used in small workgroup or small office networks.

The ease of enabling printer sharing would depend on the hardware you are using. If you have a network printer, then setting up tasks will be simpler. All you need to do is follow the instructions that came with the printer. If your printer is network-capable, using a print server to connect to your router's Ethernet port and your printer is highly recommended and extremely important to ensure smooth printer sharing and printing operations. If you happen to be unable to find a compatible print server, you can always use a third-party print server with any printer, provided that the devices share either a USB or parallel port connection. If you are using a WiFi network, you can also use a wireless print server, which usually connects via USB or parallel port to your printer and your router.

Server Racks and Computer Server Rack Evolution

It has been interesting over the years to see how words morph so quickly in the computer IT arena. A good example has been how the term server rack evolved from the phrases enclosure cabinet, data cabinet and computer rack that was made to hold computer hardware on 19" EIA rack rails.

Most of these type enclosure cabinets were shallow from 20" to 25" deep and were basically the same for many years. Things began to change when deeper cabinets were needed as blade servers became more popular several years ago. Until blade servers entered the market, most servers were towers or 15-20" deep that could be rack mounted in 4U-8U space.

Many popular blade servers were designed to only take up 1U-4U of space. This created the opportunity to put a lot more servers in a computer rack. An interesting problem was created however when blade servers were put in such a small "U" space. The servers became much deeper, up to 42" deep in some cases, and also ran much hotter. Heat disperse was addressed by pulling air from the front of the server and blowing it out the back.

These deeper hot running servers no longer worked well in a conventional enclosure cabinet or computer rack and a new style computer rack was developed. This cabinet had to be deeper and allow for airflow from the front to rear to keep the servers from burning up. The industry term began to morph to server rack.

The rack rails of the server racks also changed from a long time standard of 10/32 tapped rack rails to a punched square hole that held an insert for a 6mm cage nut and screw. Dell, along with other manufactures, makes sliding rails that attach to the server rack with a special flange that fits into the square hole without the use rack screws.

Currently, racks are made in many versions. Some have a combination plexi door with special vents cut in the frame for the front door and a screen rear door. Other server rack versions have a locking screen door in front and a double screen door in the back to save space as it opens into an aisle.
