7 main parts to a computer:
Motherboard is the most important part of the computer
cpu is the central processing unit
it runs the software and processes data
it's usually like a fan
RAM: is the random access memory . sits on motherboard. you'll find 1,2 or 3 banks of RAM
stick of memory added to motherboard (in a slot)
video card connects to motherboard in vid card slide
gamers update vid cards every 3 to 6 months
power suppl...all the wires are from there
hard disk holds info even when power is off
old machine: contains personal info. deleting is no enough. you've got to DESTROY the drive. ppl can get through it if they use the right toold
cds and dvds can't handle deep scratches. they keep data and stuff u wanna save on it.
