What is in the computer?

What is in a computer? well it really depends on what someone does with it. But all working computers have a few simple things. 1. motherboard (main part of computer) 2. processor (this allows the user to actually do things on it and the higher the CPU speed the faster and better it does those things) 3. Power supply (transfers electricity throughout the PC) 4. Ram Chips (Memory transfer station) 5. Hard drive (holds all saved info for later access) 6. video chip (most modern computers come with it built in motherboard but most people prefer PCI/e slot cards for the fact that most cases they are better) 7. chip-sets (this is built into the motherboard but without it your computer will not run)

And that is what is inside a computer. but some people differ from that by adding other cards to the PCI, AGP, or PCI/E slots.

ps. most computers come with a built in sound card but few do not which means you would have to buy a Sound card and fill up a free slot on motherboard.
