A computer card is an expansion device that provides an existing computer with certain added

capabilities. What these capabilities are depends of course on the computer card. Some examples of

popular computer cards include high speed serial port cards, USB cards, fire-wire cards, and parallel

cards. Widely varying both in size, price, and purpose, these cards have the ability to make your

computer perform functions or connect with external devices that it couldn't have previously.

Expansion slots are located on the motherboard, and openings on the back of the computer allow

the ports on the cards that go in the slots to be accessed.

The picture below shows the SoundBlaster Live sound card, with additional ports attached to it

through an IDE cable. There are several types of expansion slots, including AGP, PCIe (also known as

PCIexpress), PCI, and ISA.

The top card of the SoundBlaster Live sound card plugs into a PCI expansion slot, while the bottom

card sends and receives its data to and from the larger card through an IDE cable. The smaller card

simply needs an empty spot in the case to be mounted to. It does not need to be placed into an

expansion slot on the motherboard.

Types of Expansion Slots:

ISA AGP PCI PCIe, which is short for PCIexpress

1.ISA SlotsISA slots are an older type of expansion slot, twice as big as PCI slots and slower than PCI slots as

well. ISA slots are usually black, while PCI slots are usually white. ISA slots are not used much

anymore, but most computers still have at least one of them.

ISA networking cards, ISA sound cards, ISA video cards, and other types of ISA expansion cards can

be used in the ISA slots.

2.PCI Slots

The photo above is a picture of a PCI expansion slot, the most common expansion slot. PCI slots can

handle 64 bits of data at a time, twice as fast as ISA slots, which can only handle 32 bits of data at a

time. PCI is an abbreviation for "Peripheral Component Interconnect." A 64-bit PCI slot has 64

connections to the motherboard, and each connection is capable of handling 1 bit of data at a time.

A 32-bit ISA slot has 32 connections to the motherboard, each handling one bit of data at a

time. (Note: Older technology ISA slots are 8-bit and 16-bit. The newer EISA, (or Extended ISA), slots

are capable of 32-bit data transfer. Older PCI technology is 32-bit. The newer PCI technology is 64-

bit.)

The diagram below shows how to properly insert a PCI card into an empty PCI expansion slot.

As technology changes, new expansion cards become available. These include video cards, whichallow a monitor to be connected to the computer, sound cards, which allow speakers and a

microphone to be connected to the computer, and networking cards, which allow computers to be

linked together. There are also many other types of expansion cards. Below is a photograph of a

Promise PCI expansion card. It allows you to connect up to four additional drives to your computer

with IDE cables. This expansion card provides data transfer rates of up to 66,000,000 bits per second,

(or 66Mbs/sec). This technology is also known as Ultra ATA/66. ATA is an abbreviation for "Advanced

Technology Attachment." Ultra ATA/66 is also known as Ultra DMA/66. DMA is an abbreviation for

"Direct Memory Access." Ultra DMA/66 devices can directly access the RAM, transferring 66 million

bits of data per second.

Below is a picture of Creative Labs Sound Blaster Live Value PCI sound card. A sound card is what

processes sound and allows speakers and a microphone to be hooked up to the computer. When

you hear music coming from your computer's speakers, the sound card's digital signal processor,

also known as the DSP, is working together with the digital-to-analog converter, also known as theDAC, processing and converting digital sound data (electrical pulses represented by binary code) to

analog sound data (increases and decreases in electrical pulses that the speaker interprets and

generates as increases and decreases in tone, frequency, and volume.) When you talk into your

computer's microphone, the sound card's digital signal processor works along with the analog-to-

digital converter to process and convert analog sound data to digital sound data, which can be saved

onto your computers memory. Record players are analog they are made of tiny engravings that

the needle moves through, that move back and forth in a wave shape to change the frequency of the

sound. Computers, however, are digital. A music file stored on a computer hard drive is stored as a

series of positive and negatively (north and south) magnetically charged sectors on the hard

drive. These are represented by 1s and 0s in what is called binary code. Different sequences of these

magnetic charges instruct the computer to perform different tasks, and in this case, tell the

computer what frequencies and volumes to play when playing the music file.

Better sound cards have better sound; however, you can save a ton of money by just buying a

mediocre sound card. The Sound Blaster Live Value card allows you to connect a sound input device,

like a CD-Player or radio, a microphone, front speakers, rear speakers, and a joystick or MIDI

instrument, like an MIDI keyboard. The front and rear speakers can be combined together to

produce stereo surround sound. Just like the video card, the sound card uses its own little processor

to process sound data.

Below is a picture of a SCSI (pronounced sscuhzy) PCI expansion card. SCSI is an abbreviation for

"Small Computer Interface System." With a SCSI expansion card, you can connect up to fifteen

devices to one SCSI connection. SCSI is one of the fastest data transfer interfaces there is. SCSI cards

are available with transfer rates up to 320 MB per second! The Ultra320 SCSI-3 interface is the

fastest SCSI interface, with a 320MB/sec data transfer rate! Below is a picture of a PCI SCSI

expansion card.

3.AGP Slots

The AGP expansion slot connects AGP video cards to the motherboard. The video card shown above

is an AGP GeForce FX 5500. Video cards are also known as graphics cards. They process video and

image data that will be displayed on your screen. The monitor plugs into the video card. AGP is an

abbreviation for Accelerated Graphics Port. Most AGP video cards are capable of a higher data

transfer rate than PCI video cards. Video cards, like the one shown above, simply plug into an AGP

slot and connect a monitor or other video display device to a computer, usually through the VGA

port. The video card shown above has three different ports, for three different types of monitors.

The "DVI Out" connector connects to a digital video display. DVI is an abbreviation for Digital Video

Interface. Video cards with a TV output connection are capable of displaying a computer's video on a

television instead of a computer monitor, which is great for playing movies on your

computer. Unfortunately, most televisions only support a very low resolution and refresh rate when

hooked up to computers. Video cards with a TV input connection are able of displaying a television's

video on a computer. This allows you to record television programs onto your computers hard

drive. The VGA connection is the standard connection to most monitors.

The quality of the display depends mostly on the type of video card, but also on the type of

monitor. There are many factors in determining how good a video card is, but the most important,

in my opinion, is video-RAM. Video cards have their own RAM, called video-RAM and the more

RAM the video card has the faster the video card, and your computer, will run. Go to Display

Properties from the control panel or by right clicking on your desktop and clicking Properties and

then click Settings and click Adapter to see how much video RAM your current video card has. If

you have less then 128 megabytes of Video-RAM in your desktop, and you play a lot of computer

games, I would highly recommend upgrading to a video card with 128 megabytes of video-RAM,

such as the NVIDIA GeForce MX400 128Mb PCI, which goes in the PCI expansion slot. After

upgrading from a measly eight megabyte video card to the NVIDIA GeForce MX4000 128MB PCI

video card, your computer performed twice as fast! Games that used to take up to fifteen minutesto load would load in seconds!

Anyway, lets get back to talking about AGP cards. The photograph below shows what an AGP

expansion slot looks like.

AGP slots and cards come in four different modes, and you must be careful to match the card and

slot with the correct mode. Some AGP cards and AGP slots are capable of running in more than one

mode. AGP 1x mode is the oldest; it transfers data at 266MBs per second. AGP 2x mode transfers

data at 533megabytes per second. AGP 4x mode transfers data at 1.07 gigabytes (1007 megabytes)

per second. The latest AGP mode is AGP 8x. It transfers data at 2.14gigabytes (2140 megabytes) per

second!

4.PCI EXPRESS

PCI Express is a new technology that is slowly replacing AGP. PCI Express x16 slots can transfer data

at 4GBs per second, which is about twice as fast as an AGP 8x slot! PCIe stands for PCI Express, or

PCIexpress. PCI Express slots come in five different sizes and speeds: PCIe x1, PCIe x2, PCIe x4, PCIe

x8, and PCIe x16. PCIe x16 slots are used for graphics cards.
