The program is an ordered set of instructions (instructions, directives) and instructions executed by the computer.

Executing program commands in a given sequence leads to a specific data change on the computer.

The software can be divided into three groups:

• system: operating systems, service programs, drivers, etc. - provide PC operation, distribution of its resources, support dialogue with the user;
• Applied: text and image editors, databases, spreadsheets, etc. - provide solutions to various tasks of human activity;
• instrumental: programming languages.

To create software products, hundreds of people-years of skilled work (for example, the Windows system) are spent.
