Software

Defining Software

The distinction between software and hardware is sometimes confusing because they are so integrally linked. Clearly, when you purchase a program, you are buying software. But to buy the software, you need to buy the disk(hardware) on which the software is recorded.

Software is often divided into two categories:
Systems Software: Includes the operating system and all the utilities that enable the computer to function.
Applications Software : Includes programs that do real work for users. For example, word processors, spreadsheets, and database management systems fall under the category of applications software.

From what the information above tells me, Software is a disk or a programme which you have to upload onto computers to have access to. Obviously, Software will only work on a computer.
