Memory Address

In computing, memory address is a data concept used at various levels by software and hardware to access the computer's primary storage memory. Memory addresses are fixed-length sequences of bits conventionally displayed and manipulated as unsigned integers. Such numerical semantic bases itself upon features of CPU (such as the instruction pointer and incremental address registers), as well upon use of the memory like an array endorsed by various programming languages.

Famous quotes containing the words address and/or memory:

    It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity but to their self-love, and never talk to them of our necessities but of their advantages.
    Adam Smith (1723–1790)

    Any memory for the most part depending on chance.
    Philip Larkin (1922–1986)
