Memory Mapping

In computing, memory mapping may refer to:

  • Memory-mapped file, also known as mmap
  • Memory-mapped I/O, an alternative to port I/O; a communication between CPU and peripheral device using the same instructions, and same bus, as between CPU and memory
  • Virtual memory, technique which gives an application program the impression that it has contiguous working memory, while in fact it is physically fragmented and may even overflow on to disk storage

Famous quotes containing the word memory:

    “Then, lastly, let some weekly strewings be
    Devoted to the memory of me:
    Then shall my ghost not walk about, but keep
    Still in the cool and silent shades of sleep.”
    —Robert Herrick (1591–1674)
