The integrated circuit is an essential invention to produce modern software systems. [2]The first use of the word software is credited to mathematician John Wilder Tukey in 1958. [3]
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.
Application software is any computer program that is intended for end-user use – not operating, administering or programming the computer. An application (app, application program, software application) is any program that can be categorized as application software.
Embedded software is computer software, written to control machines or devices that are not typically thought of as computers, commonly known as embedded systems.It is typically specialized for the particular hardware that it runs on and has time and memory constraints. [1]
A software system is a system of intercommunicating components based on software forming part of a computer system (a combination of hardware and software). It "consists of a number of separate programs, configuration files, which are used to set up these programs, system documentation, which describes the structure of the system, and user documentation, which explains how to use the system".
A computer program is a sequence or set [a] of instructions in a programming language for a computer to execute.It is one component of software, which also includes documentation and other intangible components.
Constructing for verification means building software in such a way that faults can be ferreted out readily by the software engineers writing the software, as well as during independent testing and operational activities.
Software engineering is a field within computer science focused on designing, developing, testing, and maintaining of software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
