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:

    “She might have been old once and now, miraculously, young again—but with the memory of that other life intact. She seemed to know the world down there in the dark hall and beyond for what it was. Yet knowing, she still longed to leave this safe, sunlit place at the top of the house for the challenge there.”
    —Paule Marshall (b. 1929)
