  2. Memory hierarchy - Wikipedia

    en.wikipedia.org/wiki/Memory_hierarchy

    In computer organisation, the memory hierarchy separates computer storage into a hierarchy based on response time. Since response time, complexity, and capacity are related, the levels may also be distinguished by their performance and controlling technologies. [1] Memory hierarchy affects performance in computer architectural design, algorithm ...

    en.wikipedia.org/wiki/Privileged_access_management

    Privileged access management. Privileged Access Management (PAM) is a type of identity management and branch of cybersecurity that focuses on the control, monitoring, and protection of privileged accounts within an organization. Accounts with privileged status grant users enhanced permissions, making them prime targets for attackers due to ...

    en.wikipedia.org/wiki/Object_storage

    Object storage. Object storage (also known as object-based storage [1] or blob storage) is a computer data storage approach that manages data as "blobs" or "objects", as opposed to other storage architectures like file systems which manages data as a file hierarchy, and block storage which manages data as blocks within sectors and tracks. [2]

  5. Data management - Wikipedia

    en.wikipedia.org/wiki/Data_management

    The concept of data management arose in the 1980s as technology moved from sequential processing (first punched cards, then magnetic tape) to random access storage.. Since it was now possible to store a discrete fact and quickly access it using random access disk technology, those suggesting that data management was more important than business process management used arguments such as "a ...

  6. Virtual memory - Wikipedia

    en.wikipedia.org/wiki/Virtual_memory

    Virtual memory combines active RAM and inactive memory on DASD to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" which "creates the illusion to users of a very large (main) memory".

  7. Memory management - Wikipedia

    en.wikipedia.org/wiki/Memory_management

    Memory management is a form of resource management applied to computer memory. The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed. This is critical to any advanced computer system where more than a single process ...
