|Types of software|
Practical computer systems divide software systems into three major classes: system software, programming software and application software, although the distinction is arbitrary, and often blurred.
System software helps run the computer hardware and computer system. It includes:
The purpose of systems software is to unburden the applications programmer from the details of the particular computer complex being used, including such accessory devices as communications, printers, readers, displays, keyboards, etc. And also to partition the computer's resources such as memory and processor time in a safe and stable manner.
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:
An Integrated development environment (IDE) is a single application that attempts to manage all these functions.
Application software allows end users to accomplish one or more specific (not directly computer development related) tasks. Typical applications include:
telecommunications, (ie the internet and everything that flows on it)
Application software exists for and has impacted a wide variety of topics.
