  2. Process (computing) - Wikipedia

    en.wikipedia.org/wiki/Process_(computing)

    The state is typically stored in computer registers when the process is executing, and in memory otherwise. [ 1 ] The operating system holds most of this information about active processes in data structures called process control blocks .

  3. Computer data storage - Wikipedia

    en.wikipedia.org/wiki/Computer_data_storage

    Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. [1]: 15–16 The central processing unit (CPU) of a computer is

  4. Computer memory - Wikipedia

    en.wikipedia.org/wiki/Computer_memory

    Computer memory stores information, such as data and programs, for immediate use in the computer. [2] The term memory is often synonymous with the terms RAM, main memory, or primary storage. Archaic synonyms for main memory include core (for magnetic core memory) and store. [3]

  5. Memory cell (computing) - Wikipedia

    en.wikipedia.org/wiki/Memory_cell_(computing)

    The memory cell is the fundamental building block of computer memory. The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 ( high voltage level) and reset to store a logic 0 (low voltage level).

  6. Random-access memory - Wikipedia

    en.wikipedia.org/wiki/Random-access_memory

    Magnetic core memory was the standard form of computer memory until displaced by semiconductor memory in integrated circuits (ICs) during the early 1970s. [ 10 ] Prior to the development of integrated read-only memory (ROM) circuits, permanent (or read-only ) random-access memory was often constructed using diode matrices driven by address ...

  7. Memory architecture - Wikipedia

    en.wikipedia.org/wiki/Memory_architecture

    Memory architecture describes the methods used to implement electronic computer data storage in a manner that is a combination of the fastest, most reliable, most durable, and least expensive way to store and retrieve information. Depending on the specific application, a compromise of one of these requirements may be necessary in order to ...

  8. Processor (computing) - Wikipedia

    en.wikipedia.org/wiki/Processor_(computing)

    In computing and computer science, a processor or processing unit is an electrical component (digital circuit) that performs operations on an external data source, usually memory or some other data stream. [1]

  9. Data storage - Wikipedia

    en.wikipedia.org/wiki/Data_storage

    Electronic data storage requires electrical power to store and retrieve data. Data storage in a digital, machine-readable medium is sometimes called digital data. Computer data storage is one of the core functions of a general-purpose computer. Electronic documents can be stored in much less space than paper documents. [3]
