The user controls the computer, of course. But I think you're asking what the brain, or heart of the computer is and that's the processor.
It is of no importance at all to the average computer user. All it tells you is the clock that the machine runs on and there are many other variables (both hardware and software) that affect the actual performance of the computer in actual use on real world problems. Without accounting for these variables, processor speed will be very misleading. For many people processor speed is important as a "boasting number" so that they can claim to be better than another person!
The speed of processor is very high in comparison to that of user and input/output device.... So if processor is made to wait and work in the speed to user and I/O devices the system becomes very slow... Hence, in order to make full use of processor's speed MEMORY MANAGEMENT is done
It is the main control unit in a computer. It is like the 'brain' of the computer. It does controls all hardware, and executes software commands, like: Math Calculations Logical Operations (Comparison, differencing, etc.) Processing data from memory If there is no processor in a computer, the screen will simply stay blank when you power on the computer, and nothing will happen until you switch the computer off. You NEED the processor in order to use the computer.
The three groups are Input devices, Output devices, and Processor. Input - A device that the user enters data to the computer. Output - A device that shows data to the user Processor - A computer component that is the "Brain" of the computer. It does the thinking for the computer at lighting fast speeds.

multitasking
There is more to it then that. Some processor's that have a speed of 3.0GHz can process less data then one that is 1.7 GHz. To answer your question, because you could spend a thousand dollars and get a slower computer then one for 700.00.
Multi-tasking.
parallel processing
It IS the consumer's connection ! The speed at which web pages load - is entirely dependent on the speed of the end-user's connection - AND - the speed at which the end-user's computer can process the incoming data !
An application package is a set of computer programs which perform the basic function of enabling the end user of the computer to perform their required tasks on the computer in a productive manner, for example the word processor package will enable the user to type, print and store documents in their computer in a manner they appreciate and understand.
