  9. 9. • Computer 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. • 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 dependent 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.  Video games (except the hardware part) Software Source: http://www.wikipedia.com
  10. 10. • System software helps run the computer hardware and computer system. It includes a combination of the following:  device drivers  operating systems  servers  utilities  windowing systems System Software
  11. 11. • Programming software usually provides tools to assist a programmer in writing computer programs, and software using different programming languages in a more convenient way. The tools include:  compilers  debuggers  interpreters  linkers  text editors Programming Software
  12. 12. • Application software allows end users to accomplish one or more specific (not directly computer development related) tasks. Typical applications include:  industrial automation  business software  video games  quantum chemistry and solid state physics software  telecommunications (i.e., the Internet and everything that flows on it)  databases  educational software  medical software  military software  molecular modeling software  image editing  spreadsheet  simulation software  Word processing  Decision making software Application Software
