Computer Programs

Instructions to perform logic operations on data.

The Cambridge Dictionary defines a computer program as "a set of instructions that makes a computer do a particular thing."

The main idea of a computer program is to make logic operations on some kind of data (for example, numbers, texts, images, music, videos etc). This defines the two main categories of operations performed by a computer program:

  • accessing information / storing information
  • making operations on that information

For example, a spreadsheet program such as Microsoft Excel can:

  • Load or save numbers from a file on the hard-drive
  • Apply operations on these numbers (additions, etc)
