computer software falls into one of three categories: compilers and other translator programs, software applications, and system software. Describe and give examples of each.

All three types of software are essential for the successful operation of a computer. Compliers are the applications that translate programming code into actual software applications professionals can use to do their jobs. Examples are the compilers used for translating C++, C# or in legacy systems, COBOL, into actual applications for use. The compiler takes source code and transforms the many logic conditions, branching and definition statements present in source code into applications. Software applications are those programs that users interact with to do their jobs, including Microsoft Excel, PowerPoint, Word and millions of others. Applications are often designed to support a specific series of tasks or a significant process area of a business, as Enterprise Resource Planning (ERP) is designed to accomplish for example. The third type of software, systems software, is the operating systems used for managing the many functions of the computer itself. The role of the operating system is that of orchestrator; it keeps the many subsystems, programs and subtasks that make an entire computer work synchronized so applications can complete tasks. Microsoft Windows XP, Windows 7.0, 8,0 and the Apple Macintosh X are all examples of operating systems.

Following the transition fo text-based operating systems to relatively simple graphical interfaces, Apple and Microsoft led the development of highly sophisticated graphical user-interface-based operating systems capable of streamlining complex processes across an entire enterprise. The introduction of operating systems entirely graphically-based with Microsoft Windows XP and Windows 7 signaled another shift in the development of this type of software.
