What is Software?
Software refers to a set of instructions or programs that tell a computer what to do. It is a collection of data, instructions, and algorithms that are used to operate a computer and execute specific tasks. There are two main types of software: system software (operating systems, utilities) and application software (productivity, entertainment, etc.).
System Software

Functions of system software:
- Process management: manages processes and threads.

- Productivity software (Microsoft Office, Google Docs)
- Entertainment software (games, media players)
- Educational software (learning management systems, tutorials)
