IGCSE Computer Science

Computer programs are great at processing data.

Data can be input into a computer program and then stored and processed. It can also be output for display on a monitor, for example.

This short introduction to programming will give you the tools to write your own computer programs.

These tools will include understanding how computer programs:

1. sequence instructions
2. select which instructions to execute/run
3. repeat instructions multiple times
4. process data sets eg arrays
5. count
6. sum
