Software

The software is a subclass of computer software that uses the functions of a computer directly and in detail a task that the user wants to perform.

he should be compared with system software which is involved in integrating a computer's various functions, but usually not directly apply them in carrying out tasks that benefit the user.

In this context the term application covers both the software and its implementation. A simple, if imperfect analogy in the world of hardware would be the relationship between an electric light bulb (an application) to an electric power generation plant (a system).


The power plant generates electricity only, not in itself any real use until used for a program that the electric light that performs a service that benefits the user. Typical examples of software applications are word processors, spreadsheets, and media players. Multiple applications bundled together in a package are sometimes referred to as an application suite.

Some can come together in a word processor, a spreadsheet, and several other discrete applications.

The separate applications in a suite usually have a user interface that have something in common which makes it easier for users to learn and use each application.

And often may have some capability to interact with each other in ways beneficial to the user.

For example, a spreadsheet can be embedded into a word processor document even though it had been created in the separate spreadsheet application. User-written software tailors systems to meet user's specific needs.

User-written software include Spreadsheet templates, word processor macros, scientific simulations, graphics and animation scripts.

Even email filters are a kind of user programs.

Users create this software themselves and often overlook how important it is. In some types of embedded systems, software and operating system can be separated for the user, as in the case of software used to control a VCR, DVD player or microwave ..
