Conventional Memory

In DOS memory management, conventional memory, also called base memory, is the first 640 kilobytes (640 × 1024 bytes) of the memory on IBM PC or compatible systems. It is the read-write memory usable by the operating system and application programs. As memory prices rapidly declined, this design decision became a limitation in the use of large memory capacities until the introduction of operating systems and processors that made it irrelevant.

Famous quotes containing the words conventional and/or memory:

    First it must be known that only a spoken word or a conventional sign is an equivocal or univocal term; therefore a mental content or concept is, strictly speaking, neither equivocal nor univocal.
    William of Occam (c. 1285–1349)

    Vashtar: So it’s finished. A structure to house one man and the greatest treasure of all time.
    Senta: And a structure that will last for all time.
    Vashtar: Only history will tell that.
    Senta: Sire, will he not be remembered?
    Vashtar: Yes, he’ll be remembered. The pyramid’ll keep his memory alive. In that he built better than he knew.
    William Faulkner (1897–1962)
