v. t. e. An operating system ( OS) is system software that manages computer hardware and software resources, and provides common services for computer programs . Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals ...

Multitasking is a common feature of computer operating systems since at least the 1960s. It allows more efficient use of the computer hardware; when a program is waiting for some external event such as a user input or an input/output transfer with a peripheral to complete, the central processor can still be used with another program.
Collaborative software is a broad concept that overlaps considerably with computer-supported cooperative work (CSCW). According to Carstensen and Schmidt (1999), groupware is part of CSCW. The authors claim that CSCW, and thereby groupware, addresses "how collaborative activities and their coordination can be supported by means of computer ...
Functional programs do not have assignment statements, that is, the value of a variable in a functional program never changes once defined. This eliminates any chances of side effects because any variable can be replaced with its actual value at any point of execution. So, functional programs are referentially transparent. [77]
Coding best practices. Coding best practices or programming best practices are a set of informal, sometimes personal, rules ( best practices) that many software developers, in computer programming follow to improve software quality. [ 1] Many computer programs require being robust and reliable for long periods of time, [ 2] so any rules need to ...
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [ 1][ 2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level programming ...
There are three broad classifications: Application software is the general designation of computer programs for performing tasks. Application software may be general-purpose ( word processing, web browsers, etc.) or have a specific purpose (accounting, truck scheduling, etc.). Application software contrasts with system software.
