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]
An operating system is difficult to define, [6] but has been called "the layer of software that manages a computer's resources for its users and their applications". [7] ...
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]
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.
PDP-11 CPU board. Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case.
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.
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.
