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.
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]
In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [1]
Software development is the process of designing and implementing a software solution to satisfy a user.The process is more encompassing than programming, writing code, in that it includes conceiving the goal, evaluating feasibility, analyzing requirements, design, testing and release.
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]
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.
Software as a service (SaaS / s æ s / [1]) is a cloud computing service model where the provider offers use of application software to a client and manages all needed physical and software resources. [2]
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development.It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management.
