What is software ? What is the difference between a software process and a software product ?

Software refers to a collection of programs, data, and instructions that tell a computer what to do. It is a set of instructions or programs that are designed to perform specific tasks on a computer or other electronic devices.

Software can be classified into two main categories:

1. System software is designed to manage and control the computer hardware and provide a platform for other software to run on.
