2. Computer systems
A computer system takes a set of digital inputs, processes them and creates a set of outputs. This is done by a combination of hardware and software.
In other words, you put some data into a computer (input), something happens to that data (processing) and then the computer puts out a result (output).
In order to do this, the computer needs instructions to tell it what to do. The instructions are provided by a program.

Desktops, laptops, smart phones and tablets are all examples of computer systems. They all have input, output, processing and storage capability.
