What is function of central processing unit?

Answer 1

CPU stands for central processing unit. Overall a personal computer can be divided into the following major parts from point of view of functions performed:

1. Input devices (keyboard, mouse)

2. Output devices (monitor which displays the output or results of work being done on the computer)

3. CPU (central processing unit, which is the brain of the computer which does all the processing and calculations on data inputs and provides output on screen or printer)

4. Storage devices (memories, hard disk which store data).

Many times in common language the CPU term is used for the computer box unit which contains motherboard, processor, hard disk, CD/DVD and floppy drives. This is the box to which we connect monitor, keyboard, mouse and printer through cables. In technical terms the term CPU is used only for the processor, which fits on the motherboard.

Answer 2

The most basic explanation is the CPU acts as a phone that is in a prisoner visitation area with the keyboard and software application sitting on one side (Distressed wife and layer). and the Operating system and hard drive on the other (Guard and prisoner). If you would like a more technical explanation I would recommend looking up the OSI model first then do a cross reference search on the CPU within the OSI model.

Hope this helps!

Answer 3

The CPU's job is to send out bits of memory to other places in your memory and each memory slot has a code which the CPU uses to find the location in the memory and then send out a 1 or a 0 to that spot. And if you've ever used a flip flop that is what it is and that is what the CPU changes.

Answer 4

The CPU gives your computer the ability to compute. It handles all of the calculations and data processing that command all the other devices on your computer to carry out their functions, all the way to telling your video card what it needs to display on your screen. It is the brain, if you would. The fan that's connected to the CPU works along with the heat sink (Network of metal and metal fins directly beneath the CPU fan) to dissipate heat created by the CPU.

This is a re-post of my own answer on a similar question asked recently.

Answer 5

It could also be called CPU or prosser, its the brain of the computer, the part that does the thinking.

Answer 6

It processes the input and perform calculations and gives the output.

Answer 7

The roles of the CPU are to fetch, decode, execute, and writeback.
