gpu - make graphics
there are 2 kinds, discrete and intergrated, discrete has its own memory (graphics RAM) to use to draw its pictures, intergrated, uses your actual RAM to draw images, and is slower because it doesnt have its own memory to work with, and also takes up RAM so your applications will have less for other kinds of processing.
RAM - temporarily keeps processes and information in memory so processor can work on those processes and use the information, when RAM runs out, cpu pages things in RAM and saves it to hard drive and calls it back from hard drive when it needs to sue it.
BIOS - basic input output system, manages input and output controls
Optical Drives - uses cds and stuffs
webcam - self explanatory
mouse - allows cursor movement
keyboard - allows word input
buttons - buttons
cpu - processes math
psu - converts ac to dc power so computer can use it
operating system- controls everything, tells each component of computer wat to do
hard disk drive - stores data, 2 kinds of ways that you can connect a hard drive, SATA or PATA, SATA is faster, but PATA can connect 2 devices to one cable
sound card - makes sound
mother board - contains things like RAM, and bios chip so your computer can work. also contains cpu and heatsinks and fans. distributes power to all components in computer.
those are the core (main components) except the webcam, keyboard mouse and buttons.
thats preety much it, but this is only VERY VERY VERY VERY BASIC.
