Definition. Software can be defined more narrowly as the instructions executed by the computer hardware, or more broadly including other concepts, tools, and methods needed to make an executable system on computer hardware, such as design documents, specifications, and testing suites.
Software engineering is an engineering approach to software development. [ 1][ 2][ 3] A practitioner, called a software engineer, applies the engineering design process to develop software. The terms programmer and coder overlap software engineer, but they imply only the construction aspect of typical software engineer workload.
Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. [1] [2]
Software development is the process used to create software. Programming and maintaining the source code is the central step of this process, but it also includes conceiving the project, evaluating its feasibility, analyzing the business requirements, software design, testing, to release. Software engineering, in addition to development, also ...
Software is a set of programmed instructions stored in the memory of stored-program digital computers for execution by the processor. Software is a recent development in human history and is fundamental to the Information Age . Ada Lovelace 's programs for Charles Babbage 's Analytical Engine in the 19th century are often considered the founder ...
Software – collection of computer programs and related data that provides the information for the functioning of a computer. It is held in various forms of memory of the computer. It comprises procedures, algorithms, and documentation concerned with the operation of a data processing system. The term was coined to contrast to the term ...
System software was usually supplied by the manufacturer of the computer hardware and was intended to be used by most or all users of that system. Many operating systems come pre-packaged with basic application software. Such software is not considered system software when it can be uninstalled without affecting the functioning of other ...
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.
