  2. Computer science - Wikipedia

    en.wikipedia.org/wiki/Computer_science

    e. Computer science is the study of computation, information, and automation. [ 1][ 2][ 3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software ). [ 4][ 5][ 6] Algorithms and data structures are ...

  3. Computer architecture - Wikipedia

    en.wikipedia.org/wiki/Computer_architecture

    In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [ 1] It can sometimes be a high-level description that ignores details of the implementation. [ 2] At a more detailed level, the description may include the instruction set architecture design ...

  4. Systems analysis - Wikipedia

    en.wikipedia.org/wiki/Systems_analysis

    t. e. Systems analysis is "the process of studying a procedure or business to identify its goal and purposes and create systems and procedures that will efficiently achieve them". Another view sees systems analysis as a problem-solving technique that breaks a system down into its component pieces and analyses how well those parts work and ...

  5. Computer hardware - Wikipedia

    The case is also part of the system to control electromagnetic interference radiated by the computer and protects internal parts from electrostatic discharge. Large tower cases provide space for multiple disk drives or other peripherals and usually stand on the floor, while desktop cases provide less expansion room. All-in-one style designs ...

  6. Digital forensics - Wikipedia

    en.wikipedia.org/wiki/Digital_forensics

    Digital forensics (sometimes known as digital forensic science) is a branch of forensic science encompassing the recovery, investigation, examination, and analysis of material found in digital devices, often in relation to mobile devices and computer crime. [ 1][ 2] The term "digital forensics" was originally used as a synonym for computer ...

  7. Systems theory - Wikipedia

    en.wikipedia.org/wiki/Systems_theory

    v. t. e. Systems theory is the transdisciplinary [ 1] study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems.

  8. Distributed computing - Wikipedia

    en.wikipedia.org/wiki/Distributed_computing

    Distributed computing. Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. [ 1][ 2] The components of a distributed system communicate and coordinate their actions by passing messages to one another ...

  9. Systems development life cycle - Wikipedia

    en.wikipedia.org/wiki/Systems_development_life_cycle

    In systems engineering, information systems and software engineering, the systems development life cycle ( SDLC ), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. [ 1] The SDLC concept applies to a range of hardware and software configurations, as a ...
