More InformationVideo and Sound card we did Yesterday..

Ok what we did in class yesterday was learn about the video and sound card.

Modem- this satnds for modualtor and demodulator. Its a kind of device which allows a computer to transfer data through a cable or a telephone line. Information that is transferred to through this is in the form of analog waves, while the one that is stored in the computer is digital. Then what the modem does is converts this from one form to another. There are two types of modems ones that can be attached externally or one that comes in an extension board. The external one is attached using a port and the other one is attached to a empty expansion slot which come with the motherboard.

Video Card- this kind of card helps your computer show visual graphics. This is another expansion board that can be attached to your motherboard. Like a listener if you're a computer game player then you should buy an expensive card so evrything visual runs smoothly otherwise there's really no need.

Sound Card- This particular card makes the computer to output sound,input sound and sound which is controlled. This is also a expansion boards which can be attached to empty slot in the motherboard like the modem. Most sound cards are built-in but to a listener maybe upgrading is better.

PCI- this stands for Peripheral Component Interconnect which is one of the slots in the motherboard.

There maybe more for now lets just leave it at this!
