What Are The Four Components Of Computer Processing?

The four components of computer processing include:

• CPU

This is where the computer gets its instructions on how to do certain tasks or execute certain programs. It is often referred to as the 'brain' of the computer as this is what tells a computer to carry out tasks such as opening a new window or displaying a photo. The CPU is made up of three smaller parts including the arithmetic unit, the machine code and the instruction decoding unit.

• Memory

This works together with the CPU. Once instructions for specific tasks to be carried out are converted by the CPU into a machine code, this is then stored in the memory as a set of instructions or data.

• Input Units

These include all the devices that are connected up to the computer to feed it different information. For example, this includes the keyboard, mouse and hard drive. The name 'input' suggests that these devices are 'inputting' information and data from the outside world into the computer. They act in the same way as our ears bring noise to the brain where the information is then interpreted and understood.

• Output units

These are devices that convey information back to the individual using the computer. This will include a monitor, speakers and printer.
