Types of software
Software includes all the various forms and roles that digitally stored data may have and play in a computer (or similar system), regardless of whether the data is used as code for a CPU, or other interpreter, or whether it represents other kinds of information. Software thus encompasses a wide array of products that may be developed using different techniques such as ordinaryprogramming languages, scripting languages,microcode, or an FPGA configuration.
The types of software include web pagesdeveloped in languages and frameworks likeHTML, PHP, Perl, JSP, ASP.NET, XML, anddesktop applications like OpenOffice.org,Microsoft Word developed in languages like C,C++, Objective-C, Java, C#, or Smalltalk.Application software usually runs on an underlying software operating systems such as Linux orMicrosoft Windows. Software (or firmware) is also used in video games and for the configurable parts of the logic systems of automobiles,televisions, and other consumer electronics.
Practical computer systems divide software systems into three major classes[citation needed]: system software, programming software and application software, although the distinction is arbitrary, and often blurred.
System software
Main article: System software
System software is computer software designed to operate the computer hardware to provide basic functionality and to provide a platform for running application software.[6][7]System software includes device drivers, operating systems, servers, utilities, and window systems.
System software is responsible for managing a variety of independent hardware components, so that they can work together harmoniously. Its purpose is to unburden theapplication software programmer from the often complex details of the particular computer being used, including such accessories as communications devices, printers, device readers, displays and keyboards, and also to partition the computer's resources such as memory and processor time in a safe and stable manner
