Software
............................................................................................................................................................................................................................
A set of commands that cause a computer to operate one or more tasks. The set of commands is commonly called a program or if the set is specifically large and complex, a system. Computers cannot do any beneficial work without commands from software; thus a association of software and hardware is essential to do any computerized work. A program must tell the computer each of a set of minuscule tasks to execute, in a framework of logic, such that the computer knows exactly what to do and when to do it. See also Computer programming.Programs are created in programming languages, particularly designed to easy the development of software. In the 1950s, programming languages were numerical languages normally inherent by computer hardware; commonly, programmers said they were writing such programs in machine language.

Machine language was awkward, error-prone and difficult to replacement. In the latter 1950s, assembler language was fictional. Assembler language was almost the same as machine language, eliminate that symbolic (instead of numerical) operations and symbolic addresses were used, making the code considerably easier to change.

The programmable element to consider of computer hardware have not replaced much since the 1950s. Computers quiet have numerical behavior and numerical addresses by which data may be accessed. However, programmers now use high-level languages, which look much more like English than a string of numbers or machine codes. See also Numbering systems; Numerical representation (computers); Programming languages.

Familiar programming languages contain Basic, Java and C. Basic has been limited into Visual Basic, Visual Basic language valuable for writing the division of a program that the user talks to (i.e., the user interface or graphical user interface or GUI). Java is particularly beneficial for specifications and implementations for integrating with many kinds of systems that you're likely to run into in an enterprise environment. C and C++ are powerful but complicated languages for writing such software as systems software and games. See also Human-computer interaction; Local-area networks; Wide-area networks.

Packaged software such as word processors, spreadsheets, graphics and drawing tools, email systems and games are broadly gettable and used. Some software packages are very large; for example, enterprise resource planning (ERP) software can be used by companies to execute almost all of their so-called backoffice software work. See also Computer graphics; Electronic mail; Video games; Word processing.
