Computer software is very important when you want to operate your computer. Without the computer software, your computer would just be like a brand new Lexus car, without an engine and fuel. Without the software, your computer would just look like an empty box moping at you. It cannot perform any task without the software.
The word software is used to describe all the programs that can be found on a particular computer, which tells the computer what to do.
A program is a set of instructions given to the computer to perform particular functions. The software allows users to operate the computer effectively. It is the lifeblood of the computer.
