For the last two periods we did the presentations.
Well it was good, I've lernt a lot of interesting and useful information.
Firs of all now I know what is mother board and what it does. Mother board is the center of the computer and it controls all the prosseses that are going on in the computer. The second important thing I've learnt is about ROM(random access memory). I always thought that you store information in it, but now I know that ROM works only when the electricity is on, but when you turn the computer off it clears. I also lernt that there two types of monitors, and that they work in complietly different ways. CD player uses a laser technology to read the CD disks.
Also people talked about the video and sound cards. Video card is used to display videos and graphics. Sound card control sound supplies.
