Your question is a tad fragmented. (you already got some what?)

Anyway... At the most primitive level a computer computes. any device that can be used to assist with a mathematical algorithm is a computer. In Egypt they had an abicus. Europe developed the Slide rule, so on and so forth.

Modern computers are capable of incredable feats. From controlling cutting beams for making molds with mathmatical precision to basic manufacture of goods both small (toys) and large (Cars).

Indeed computers are used to control the air fuel mixture within cars to ensure the most efficient burn of propellant as well as Anti-lock breaking systems, traction control, virtually anything a car does has a computer behind it.

Ditto your kitchen, laundry, livingroom. Hell the modern world is addicted to computers.

Architectual Engineering. in fact ANY form of engineering

Security systems.

Air Conditioning.

Weather pattern predictions and formulae.

hell you dont need to think hard to come up with what a modern computer does.

Hope this has you thinking in the right direction now

If you want to get down to the core of what a computer does, then it can do two things:

1. Perform simple mathematical calculations.

2. Move around data.

When you compile these things just right, you end up with what you see as a computer.

A computer makes it easier to access resources like news, history, phone books, etc. A computer can help you research for school, you can type a paper a lot faster than write one, gives us the ability to send email and not letters, computers make our life easier, like i mentioned above you can do tasks effortless that used to take time so it speeds up the time needed to complete your tasks which means your done faster.
