Computer programs are everywhere
Programming is not just about conventional computer systems anymore. The world has become increasingly digital, and almost everything runs on software. Programs are now incorporated into devices such as mobile phones and tablets, labour-saving equipment around the home, and even in transportation systems.
What is a computer program?
A program is a set of instructions that a computer follows to perform a task. Programs can be extremely complex, and there can be several different layers of programs working together. Microsoft Windows, for example, is made up of millions of lines of instructions.
