Computer software, or just software, is a general term primarily used for digitally stored data such as computer programs and other kinds of information read and written by computers. Today, this includes data that has not traditionally been associated with computers, such as film, tapes and records. The term was coined in order to contrast to the old term hardware (meaning physical devices); in contrast to hardware, software is intangible, meaning it "cannot be touched". Software is also sometimes used in a more narrow sense, meaning application software only.

Examples:

• Application software, such as word processors which perform productive tasks for users.
• Firmware, which is software programmed resident to electrically programmable memory devices on board mainboards or other types of integrated hardware carriers.
• Middleware, which controls and co-ordinates distributed systems.
• System software such as operating systems, which govern computing resources and provide convenience for users.
• Software testing is a domain independent of development and programming. Software testing consists of various methods to test and declare a software product fit before it can be launched for use by either an individual or a group.
• Testware, which is an umbrella term or container term for all utilities and application software that serve in combination for testing a software package but not necessarily may optionally contribute to operational purposes. As such, testware is not a standing configuration but merely a working environment for application software or subsets thereof.
