Software means the programs and other operating information used by a computer.It is the general term for information that's recorded onto some kind of medium. For example, when you go to the video store and rent or buy a tape or DVD, what you're really getting is the software that's stored on that tape or disk. Your VCR or DVD player are hardware devices that are capable of reading the software from a tape or disk and projecting it onto your TV screen, in the form of a movie. Software is untouchable things and only seeing things, but operating program.
Your computer is a hardware device that reads software too. Most of the software on your computer comes in the form of programs. A program consists of "instructions" that tell the computer what to do, how to behave. Just as there are thousands of albums you can buy on CD for your stereo, and thousands of movies you can buy to play on your VCR or DVD player, there are thousands of programs that you can buy to run on your computer.
When you buy a computer, you don't automatically get every program produced by every software company in the world. You usually get some programs. For example, when you buy a computer it will probably have an operating system (like Windows XP) already installed on it.
There are three types of Software -------
1. Operating System Software
2. Application Software
3. Utilities Software
