Main one, your hands and brain along with common sense. Others, anti-static wrist strap, Phillips and flathead screwdrivers, needle nose pliers (in case you drop a small screw somewhere). Very basic hand tools really, but if you don't know what you're doing, don't do it! Now if you're talking electrical system(s) then you'll need a bit more if you're trying to diagnose a possible electrical problem, and this you Can't do...(judging by the question itself)

While you would only usually need a few non-magnetic screwdrivers and a static strap to replace, remove, and add hardware to a computer this question is unanswerable due to the fact that unless you either built the hardware yourself or are versed in electronic engineering you would not be able to actually repair the hardware.

Usually computer programmers. A company would tell the programmer what the hardware is intended for, and they would write the necessary driver(s) to enable the device to be used with the operating system.
Hardware and software - without either one, there would be no computer! A simplistic answer would be the motherboard and hard-drive, though without an operating system the monitor would be blank.
Sears Hardware, as all other hardware stores, sells the type of merchandise that one would need "around the house", for fixing things, doing home projects, etc. These include small and large tools, painting equipment, lawn mowers, and even exercise equipment.
