Network Adapters & Interfaces, NIC

A network card (also called network adapter, network interface card, NIC, etc.) is a piece of computer hardware designed to provide for computer communication over a computer network.Network cards used to be expansion cards to plug into a computer bus, most newer computers have a network interface built into the motherboard, so a separate network card is not required unless multiple interfaces are needed or some other type of network is used.The card implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as ethernet or token ring. This provides a base for a full network protocol stack, allowing communication among small groups of computers on the same LAN and large-scale network communications through routable protocols, such as IP.A network card typically has a twisted pair, BNC, or AUI socket where the network cable is connected, and a few LEDs to inform the user of whether the network is active, and whether or not there is data being transmitted on it. The Network Cards are typically available in 10/100/1000 Mbit/s. This means they can support a transfer rate of 10 or 100 or 1000 Mbit/s.

TV Tuner Card

A TV tuner card is a computer component(hardware) that allows television signals to be received by a computer. Most TV tuners also function as video capture cards, allowing them to record television programs onto a hard disk. In other words, you can install the TV tuner card into(inside) your computer motherboard. This will open an external port to connect an antenna or cable into your computer.Review: It works pretty well and some come with remote control. The cool thing is that currently there are four kinds of tuner cards in the market: analog, digital, hybrid, and combo TV tuners. If you want to know more about it, Google it. I’m sorry, don’t expect me to get all technical here. I’m a consumer, not Wikipedia.Cons: You need to open the computer to install it. If you are not that computer savvy, then you need a computer expert to install it for you, which means more money out of your pocket.

About Computer Hardware Recycling

There are those people who jump on board whole heartedly when they find a fresh way to recycle or benefit the earth. Others like to hold back and study a bit more about the process involved in order to be sure that the recycling process is really beneficial to the environment and that it is needed. When it gets to computer hardware recycling, the overwhelming reply has been that it is very much needed and everyone from the average consumer, all the way to the top with the computer manufacturing companies themselves are forming big movements to make sure that computers and their potentially risky component parts don’t finish up clogging the nation’s landfills. Naturally, if you are considering about getting involved in computer hardware recycling, there are some things you should know about the practice first.

Somniloquy Lets Your Computer Download Files In Its Sleep

Usually, when us modern, sensitive, environmentally-conscious types leave the computer on all night, it's because we're downloading something sizable. But what if our computers could handle that task while in sleep mode, thus saving energy?
Computer scientists at UC San Diego along with Microsoft Research have developed this USB device they dub the, which appropriately enough means "talking in one's sleep." The dongle lets you keep your computer in sleep mode, which saves a ton of energy, while remaining seemingly active on the network. So your computer will be in sleep mode, but you'll still be able to download files or receive IM or VoIP messages, and if an action that requires your computer's full attention does occur, Somniloquy will gently rouse it from its slumber.The device is actually a very low-power computer, complete with OS and flash memory, and essentially takes over as the computer's presence on the network while the actual computer is asleep. It consumes somewhere between 11 and 24 times less power than a full computer, which makes for some impressive energy savings. The creators are hoping the tech will be incorporated into future network cards so computers have this functionality out of the box

Ram Upgrade

Some very old computers that are not running programs that flew. But need to May, they are going to computers, to update, for all software, but funding may be an obstacle to the purchase of new computers. In these circumstances, it is recommended to their computer, using the necessary repairs and inclusion, rather than the former.

Sony Laptop

Earlier that laptops were a matter of luxury and have a computer for most people say, a powerful white desk with a small display and a quantity of son. On average, a person buying a computer not a laptop, because it unconsciously as something only high-end professionals. However, it was then. The scene of the computer market has greatly in recent years, more and more people are aware of the joy and comfort of a lightweight, portable computer, packaged function that appears to have advantages over a PC office.

The Computers On-board the Spacecraft

GP-B has several computers on-board the spacecraft. The main flight computer and its twin backup are called the CCCA (Command & Control Computer Assembly). These computers were assembled for GP-B by the Southwest Research Institute. They use approximately 10-year old IBM RS6000 Central Processing Units (CPUs), with 4 MB of radiation-hardened RAM memory. These computers, along with ruggedized power supplies are encased in sturdy aluminum boxes, with sides up to 1/4” thick.In addition to the A-side (main) and B-Side (backup) flight computers, the GP-B spacecraft has two other special-purpose computers—one for the Gyro Suspension System (GSS) and one for the SQUID Readout Electronics (SRE). Each of these specialized computers contains 3 MB of radiation-hardened RAM memory and custom circuit boards designed and built here at Stanford University. Because of the custom circuit boards, these computers are housed in special aluminum boxes that were also built at Stanford.

Vodafone - USB Modem Stick Review

There is a school of thought that says the days of the traditional ISP are numbered. Why? Because of mobile broadband. With every UK operator now offering a modem that uses USB, is self-installing under Windows XP and Vista, and that offers connections for download at up to 3.6Mbps, you can see why.These modems are really designed for use out and about with laptops but there is nothing to stop you plugging one into your desktop PC when you want the connection there. If there is a price war, and unlimited access comes down to a point where it competes with traditional ISPs, then the choice between fixed and mobile broadband is a no-brainer. I'll take the mobile, please.

Microsoft - Sidewinder Mouse Review

The first rule of Sidewinder Mouse? Download software from the Web. With no disc included in the otherwise comprehensive packaging, the bright startup guide is insistent that that's where you start. It's a 14MB download you need, and cleverly it's grouped with standard mice rather than the gaming menu under Microsoft's tree structure.This, then, is Microsoft's long-promised re-entry into the PC gaming hardware sector, to which it made a token gesture with the release of an Xbox 360 gamepad for PC, but otherwise left alone since abandoning the original Sidewinder gaming line many years ago. The new Sidewinder Mouse is promised to be the first in a line-up of accessories aimed very much at the serious gamer.

Canon - PIXMA MX850 Review

This is Canon's top-of-the-range multifunction machine for the SOHO market. The PIXMA MX range differs from the MP range in offering four-colour print, though it provides a separate, pigmented black ink for printing black text, too.The substantial MX850 - it's nearly as deep as it is wide - has a built-in Automatic Document Feeder (ADF) which, like the print engine, can operate on both sides of the paper in one job. This means you can perform duplex copying, to produce a two-sided copy of an original, though you'll have to wait for it.

Epson - Perfection V500 Photo Review

All-in-One printer/scanner/copier machines are all the rage at present, especially if you're trying to run a home office or small business on a fairly limited budget. However, the frustration for dedicated amateur and semi-pro photographers is that most multi-function machines manage to do several tasks reasonably well but none of them to a high enough degree of excellence.For this reason, a dedicated photo scanner or printer will always appeal to the keen snapper who demands high quality reproductions. Epson has been aware of this for some time and its Perfection Photo series has concentrated on meeting this need for those who don't have huge amounts of money but have plenty of enthusiasm.

Sennheiser - PC 350 Review

You can tell a lot from a box. The packaging these headphones come in is slick looking, sturdy and well designed (there's no moulded plastic to hack through and bust your scissors on here). And the PC 350 set itself is built along exactly the same lines.In fact the build quality is first-rate, and these headphones are solid and yet still relatively lightweight and really comfortable to wear. With their spacious ear cups cushioned with over a centimetre of black foam, we're going to go out on a limb here and state that the PC 350s are the most comfortable pair of headphones we've ever worn. Which is handy when you're settling in for a long session of Unreal Tournament.

How to Buy the Right Home Computer

Make sure the computer you end up buying has at least a dual-core processor (made by Intel). You also want to have a minimum of 2GB of RAM (or memory), though most computers now come with 3GB or 4GB. As for your hard drive, make sure it has at least 250GB of space if you are a casual computer user. If you like to play games on your computer, you should also make sure your computer has an adequate video card, not "integrated graphics".

Apple I computer, 1976.

This was the first computer made by Apple Computers Inc, which became one of the fastest growing companies in history, launching a number of innovative and influential computer hardware and software products. Most home computer users in the 1970s were hobbyists who designed and assembled their own machines. The Apple I, devised in a bedroom by Steve Wozniak, Steven Jobs and Ron Wayne, was a basic circuit board to which enthusiasts would add display units and keyboards.

Open Computer Case

I received all of my parts on time and I unpacked and checked every box to make sure that there was no damage to any of the computer parts. I set up all of my parts on a spare table and now I am ready to build my computer.Note: When installing computer hardware always unplug the power supply and all peripherals connected to the computer. Also use caution because there are sharp edges in a computer system. It is a good idea to wear a static electricity discharge wristband. The discharge strap will avoid damaging the components in the computer. Some other tools that might be needed are a non magnetic screwdriver, a pair of tweezers and an anti-static bag.

Netgear DG814 Review

Netgear is well known for its consumer targeted networking hardware and the Netgear DG814 is aimed squarely at that market. The DG814 is a basic ADSL modem/router compatible with all the ISPs using the BT Wholesale ADSL service or the Kingston Communications Karoo service. The basic product specification is an ADSL modem with a NAT router, incorporating a 4-port 10/100Mbps auto-sensing Ethernet switch. This product specification sounds like so many other routers on the market, but this one is certainly not one that likes to lurk in the dark out of sight. The case design is stunning compared to most ADSL hardware - a metallic silver finish with softly curved corners - and in fact it looks more like a component from a mini HI-FI than an ADSL modem/router.

WHOLESALE COMPUTER PARTS SUPPLIERS

There is an ongoing perception about wholesale computer parts which implies that wholesale parts being cheap are low quality and don’t have warranty for a long time. This is not true. These wholesale parts are manufactured by the authorized dealers and which signifies the reliability of these cheap items. Computer wholesale parts suppliers also provide repairing services. If you want your system to get repaired and get some of the computer parts replaced which have become damaged then you can contact these suppliers. They have technical experts who can identify any hardware failure.

CD/DVD-ROM

CD-Rom (compact disk- read only memory)
Compact Disks are computer hardware parts invented by Sony © and Philips © in 1981 in order to constitute a compact audio support of high quality allowing a direct access to the numerical tracks. It was officially launched in October 1982. To install software in your cheap computer your will need a CD-Rom.DVD-Rom (digital versatile disk- read only memory)the dvd-rom is an "alternative" for the CD-Rom whose capacity is larger than the CD-Rom
CD-writerCD-Writers are computer hardware parts very useful to save large file like graphics, pictures, and music.Access time The access time is the time that the laser takes to reach the data on the disk. It is measured in millisecond. In CD-ROM the access time is lower than 100 milliseconds and lower than 150 milliseconds in DVD-ROM. Lower the access time, the better it is.

Computer Processor Guide

First microprocessor (INTEL 4004) was invented in 1971. The processor (CPU: for Computer Processing unit) is the brain of the computer, it is the microprocessor that carries out all calculations and carries out the data management for the computer.
Two principal manufacturers of computer hardware parts are present on the market: INTEL and AMD. click on the to compare them and view some useful information on how the processor works.

Need a tiny, waterproof computer?

The Stealth WPC-500F meets IP67/NEMA 6 environmental specifications, and is cooled through advanced heat pipe technology instead of fans. An aluminum chassis also acts as a heat sink to dissipate internal heat and provide noise-free operation, using the Intel Atom processor. Its footprint measures just 7.51″ wide x 11.37″ deep x 2.97″ high. Ports include video, serial, USB, and power connections. It contains high performance hard drives built to withstand extreme temperatures, vibration, humidity, and high altitudes. The system is compatible with Windows and Linux.Obviously the WPC-500F is intended primarily for military-type uses, and will be available starting in early July. One of these bad boys will set you back a minimum $1,995.

Power Requirements and Cooling

As you can imagine, both versions of the Geforce 8800 require an active cooling solution. Almost a full length heatsink/fan exhaust system is present on the stock cooler which extracts the hot directly out of the back of the PC case. Surprisingly the cooler is really quiet, a lot more so than you would expect for a cooler of this size. Different manufacturers of course may decide to put on custom coolers on their brand of Geforce 8800. The Power requirements are somewhat confusing however. Nvidia claim that the Geforce 8800GTX uses only 5W more power than that of the Radeon X1950 XTX. Testing shows that this is not too far from the truth on average when under heavy loads. The confusing part is the The Geforce 8800 requires two PCI-e power connectors directly to the graphics card as well as the 75W of power that it will receive from the PCI-e slot. The Radeon uses only one power connector and the power from the slot. Does 5W extra need an extra power connector? Nvidia says to comply with PCI-express specifications it does. Without pointing the finger at ATI, what exactly are they trying to say about the Radeon 1950 XTX?

NVidia Geforce 8800 Series (GTS/GTX)

The initial release of the Geforce 8800 will come in two types. Firstly the flagship card, the Geforce 8800GTX the bigger brother of the pair if you like. The GTX version of Nvidia’s Geforce 8800 will be clocked at the higher speed, be fitted with faster memory chips and a memory bus width 64-bits wider than the 8800GTS. The GTS version will still however be built with the same technology in mind. The same core and the same compatibility with DirectX10 and all of its new features. Of course you will be able to pick up the GTS version for a fair amount less than the Geforce 8800GTX.Nvidia has changed something major inside the Geforce for the release of the 8800 series. Meet the stream processor. The Stream Processor is a combination of pixel shaders and vertex shaders combined into one. These stream processors are capable of handling data that would normally be sent to either of these processors. In turn this makes the system a whole lot more efficient.

Computer Components

Using a picture of the inside of a computer, I have labeled where each component is inside the computer. This will be the most helpful if you are looking for information before you repair or upgrade the components in your computer.

Towards a greener computer–but what does that really do?

MSI that the company has recently invented the world’s first powerless air cooler for computer motherboards. For those new to computer hardware, as we ignore and advance computer technologies by making them faster and store more data, cramming more and more transistors into a piece of silicon, the heat generated by all these components start becoming a non-negligible problem–as anyone managing a data center with hundreds of computers will identify with.
There are many ways to cool the insides of a computer, but the most common is through the use of heatsinks and fan’s. Computer hardware junkies prefer a more advanced hack: a more quiet and efficient way of dissipating heat from their overclocked CPU’s. This invention by MSI makes the fan inside your computer power-free, thus less power drawn from the computer power supply.

The graphic cards play important role for gamers, graphic designers and 3D animators who tend to require optimum displays for their work as well as faster rendering in order to efficiently tone up their work whereas integrated or onboard graphics were capable of handling most day-to-day work and supports basic usage to run windows and it's features.
The concept of onboard graphics really came up when Intel integrated graphics with its 810-chipset based motherboards for the PIII processor. Intel didn't leave an option for putting in an additional graphics card, forcing people to use only onboard graphics, which eliminated a lot of graphics cards from the market. Intel later came up with the provision to add graphics cards as well, and this changed the face of the graphics market.People didn't feel the need to buy a separate graphics card, because the onboard card served the purpose well. Intel brought iterations of its onboard graphics, with the latest one being the Extreme Graphics 2 core for the P4 processor. Along the way, two major graphics manufacturers joined the race by introducing their motherboard chipsets with onboard graphics. These were NVIDIA with its Nforce and Nforce 2 chipsets, and ATI with its latest Radeon 9100 IGP (Integrated Graphics Port). So today, with graphics manufacturers in the race, onboard graphics have become quite powerful. You can play games, watch movies, or run high-end graphics applications. That brings us to the million-dollar question of why go for a separate graphics card.

The Motherboards Guide

The principal part of a cheap computer is the motherboard; like many other things, motherboards have different manufacturers. Brand-name manufacturers of computer hardware parts don’t want users swapping their motherboard for other manufacturer’s motherboards.
If you have a brand-name computer you may be required to purchase a new motherboard from the same manufacturer.

Graphic card

Graphic cards, sometimes called video card, are computer hardware parts charged to send the graphic data to the monitor.
The best graphic card is the AGP but your motherboard must be equipped with an AGP expansion slot. Powerful graphic card is important for graphic designers and people who like to play game on their computer because they provide good resolution. The AGP is not necessary for everyday tasks.

Buffalo's new hard drive comes small and encrypted

Dusseldorf - Users have to enter the correct password to access new hard drives offered by Buffalo. The HDS-PH160U2 and the HDS-PH320U2 come with a hardware-based encryption that automatically engages. The new drives from the MiniStation-Pro line come with either 160 or 320 GB capacity at a price of either 105 or 199 euros (164.81 dollars or 312.35 dollars). According to the manufacturer, the drives are particularly resistant to jolts.

Computer Wholesale Hardware Vendors

Many of the kids like to learn about the games and softwares and always keep asking what the purpose of computer hardware is. Teaching computer hardware to kids is the basic step for them to know about typical hardware and its functions. Computer hardware for graphics includes a video and VGA card which helps in displaying colors. If you want to increase resolution of your system or may want high quality graphics then you might be needing hardware of different types.

Server (computing)

Server used as an adjective, as in server operating system, refers to the product's ability to handle multiple requests, and is said to be "server-grade". A server operating system is intended or better enabled to run server applications. The differences between the server and workstation versions of a product can vary from the removal of an arbitrary software limits due to licensing, as in the case of Windows 2000, or the addition of bundled applications as in Mac OS X Server.

How to use capture card

The best quality in analog video capture is available if you use a special video-capture card. Analog-capture cards are available at many computer and electronics retailers. A capture card actually connects to the motherboard inside your computer — so installation will require some expertise in working with computer hardware. Also, make sure that your computer actually has room to add an expansion card. I briefly discuss how to identify empty expansion slots and install a FireWire card in a Windows PC. Installing an analog capture card is very similar. If you buy a capture card, make sure it can capture analog video. Many FireWire cards are marketed as digital-video capture cards, but if you don’t read the packaging carefully, you might be confused about the card’s capabilities. If a FireWire card doesn’t specifically say that it can also capture analog video, assume that it can’t.

How Sound Cards Work

­Before the invention of the sound card, a PC could make one sound - a beep. Although the computer could change the beep's frequency and duration, it couldn't change the volume or create other sounds.
At first, the beep acted primarily as a signal or a warning. Later, developers created music for the earliest PC games using beeps of different pitches and lengths. This music was not particularly realistic -- you can hear samples from some of these soundtracks at Crossfire Designs.

Computer Hardware Architecture Design

Architecture is a way of looking at the fundamental operational structure of the computer. It is the blueprint of the requirements and design implementations for the various parts of a computer focusing largely on the way by which the central processing unit (CPU) performs internally and accesses addresses in memory. The key to a successful computing system is to select and interconnect hardware components that results in that a functional, cost-effective performance-driven machine. The topic of computer architecture addresses this. Instruction set architecture; Computer organization and System Design are three underlying aspects which need to be addressed
I will now discuss two CPU design philosophies which represent two controversial architectural philosophies
