Software refers to a set of instructions that tells the computer on what to do.

These instruction sets also called programs which provide a means for us to interact with and use the computer, all without computer programming skills.

Computer has two basic types of software :

1. System software2. Application software

System Software

• A collection of programs• Enables the application software to interact with the hardware• Background software that helps the computer manage its own resources

Application Software• “End-user” software where you use them to do tasks at home, school and work. • Two major categories

General purpose (writing letters, sending e-mail, balancing a budget, creating presentations)
