Generally speaking Software can be categorized as:

System Software:
The programs directly related to the computer hardware and perform tasks associated with controlling and utilizing computer hardware are known as system Software.
System Software does not solve a specific problem for the user rather it helps to solve a problem.

TYPES OF System Software:


Operating system are the most important system software. Operating system is a set of programs that control and supervises the hardware of a computer and provides services to application software, programmers and users of computer.
Without operating system a computer cannot do anything useful.

Data-management software includes database and file management programs that manage data for an operating system. They can organize, update and print data.

The software that is designed to perform a specific task is known as special purpose application software. This is also called Custom software. The software can perform only one task for which it has been designed. Custom software for the tasks of a large organization may be extremely complex and takes a lot of time to develop.
