-
System software: This type of software is designed to run a computers hardware and provides a platform for applications to run on top of. Examples include operating systems and language processors.
Software can be further categorized based on its purpose or domain of use. For example, computer software can be divided into:
-
Programming software: This type of software is used to write, test, and debug other software programs.
-
Utility software: This type of software is designed to help analyze, configure, optimize, or maintain a computer system.
-
Security software: This type of software is designed to protect a computer system from viruses, malware, and other security threats.

In summary, software is a set of computer programs and associated documentation and data that is used to operate computers and execute specific tasks. It can be divided into two main categories, application software and system software, and further categorized based on its purpose or domain of use.
