More about parts of the Computer
Today, we learned about the modem, sound card and video card.
A modem stands for modulate and demodulator. It is a device that allows a computer to transfer data through a cable or through a telephone line. Information that is transferred through is in the form of an analogue waves, while the one that is stored in the computer is digital. The modem converts this from one form to another. There are two types of modems. One that can be attached externally, and another that comes in an expansion board. You can attach the external one through a port, and the one that comes in an expansion board, you can attach on a vacant expansion slot which comes with the motherboard.
A sound card is what makes the computers to output sound (speakers), input sound (microphone), and control sound stored in a disc. It's also an expansion card, so you can attach them through one of the vacant expansion slots on the motherboard. Most sound cards are automatically built in when you buy your computer.
A video card is what enables the computer to show visual graphics. It is also an expansion card that you have to plug into your motherboard. You don't really need an expensive video card if you only use your computer for e-mail or homework.
A PCI express stands for Peripheral Component Interconnect is one of those slots on the motherboard. It just started appearing in around 2004, beside the normal slots. It was made to replace PCI bus.
Unfortunately, that's all I remember in today's class. I had to do some research as well, and most of the stuff came from either wikipedia.org or wisegeek.com. Next time, I'm bringing something to write with so that I don't forget. Mr. Case said anything that he said is 'testable'. It would be really convinient if I could record everything he says in a tape recorder or video camera. However, I don't have those things, and even if I do, my Dad won't let me bring it to school. Sadly to say, I have to go by old fashioned 'handwriting'. Not to worry though. I'm pretty fast in writing.
I actually took notes once- when we had the lesson about binary- but then some people were just asking me for the notes.
