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:

    “Perhaps a man like you can’t realize what it is to have a conscience and no memory at all. Do you imagine it’s pleasant to be ashamed of something you can’t even remember?”
    —Orson Welles (1915–1985)
