  2. 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]

  3. Computer data storage - Wikipedia

    en.wikipedia.org/wiki/Computer_data_storage

    Additionally, a memory management unit (MMU) is a small device between CPU and RAM recalculating the actual memory address, for example to provide an abstraction of virtual memory or other tasks. As the RAM types used for primary storage are volatile (uninitialized at start up), a computer containing only such storage would not have a source to ...

    Inside a gaming case during gameplay. 360° photograph. A full tower case. Accessories shown include: a fan controller, a DVD burner, and a USB memory card reader.. Cases can come in many different sizes and shapes, which are usually determined by the form factor of the motherboard since it is physically the largest hardware component in most computers. Consequently, personal computer form ...

    en.wikipedia.org/wiki/Data_storage

    With electronic media, the data and the recording media are sometimes referred to as "software" despite the more common use of the word to describe computer software. With ( traditional art ) static media, art materials such as crayons may be considered both equipment and medium as the wax, charcoal or chalk material from the equipment becomes ...

  7. Read-only memory - Wikipedia

    en.wikipedia.org/wiki/Read-only_memory

    Likewise, every non-trivial computer needs some form of mutable memory to record changes in its state as it executes. Forms of read-only memory were employed as non-volatile storage for programs in most early stored-program computers, such as ENIAC after 1948. (Until then it was not a stored-program computer as every program had to be manually ...

    Memory areas of the IBM PC family. In DOS memory management, conventional memory, also called base memory, is the first 640 kilobytes of the memory on IBM PC or compatible systems. It is the read-write memory directly addressable by the processor for use by the operating system and application programs.
