26/09/06

Once again we did some typing, and we went to the table for a lesson. Today in class we learned about Sound Card, Video Card, and Modem.

Modem

* two types: one of them comes in the expansion board, and the other one is connected or fixed externally.
** stands to "Modulator demodulator" which is a funny thing to pronounce
*** allows you to link to the internet
**** in my country my family and relatives used the dial-up connection to connect to the internet

Sound Card

* is what brings the sound from the computer to the speaker
** most computers already have one
*** so most times you don't have to put one in
**** it's connected to the motherboard

Video Card

* it allows the computer to show picture, images, and videos
** just like the sound card, this is also connected to the motherboard
*** the video card is responsible for everything you see in a screen
****you do not need a really good quality video card if you just need a computer for homework

Expansion Slots

Say that your computer doesn't contain a video card or a sound card and you're going to put one in, these are some of the slots that you may need.

1. PCI:
* stands for Peripheral Component Interconnect
2. PCI Express
3. AGP
* stands for Accelerated Graphics Port
