Computer System

A computer system takes a set of inputs, processes them and creates a set of outputs. This is done by a combination of hardware and software.

Input is a form of data inputted into the computer system using an input device e.g. a keyboard, mouse, touch screen, microphone and more.

Process stage is where the computer processes the data inputted into the computer. The process stage takes place within the CPU (central processing unit) of the computer or otherwise known as the microprocessor. 

The CPU needs instructions to follow in order to perform a task. These instructions are known as computer programming.

 KEYWORD =  Software is a computer program that contains the set of instructions needed by the CPU to perform a specific task. 

There are two main types of software:

1.System software

It boots up the computer when you switch on and it also tells the CPU how to communicate with other parts of the computer e.g. the hard disk or DVD drive. Another one of its key jobs is to load up the relevant application software when called for.

2.Application software
