Computer Program - Execution and Storage

Execution and Storage

Typically, computer programs are stored in non-volatile memory until requested either directly or indirectly to be executed by the computer user. Upon such a request, the program is loaded into random access memory, by a computer program called an operating system, where it can be accessed directly by the central processor. The central processor then executes ("runs") the program, instruction by instruction, until termination. A program in execution is called a process. Termination is either by normal self-termination or by error — software or hardware error.

Famous quotes containing the words execution and, execution and/or storage:

    If I were asked to chose between execution and life in prison I would, of course, chose the latter. It’s better to live somehow than not at all.
    Anton Pavlovich Chekhov (1860–1904)

    It is clear that in a monarchy, where he who commands the exceution of the laws generally thinks himself above them, there is less need of virtue than in a popular government, where the person entrusted with the execution of the laws is sensible of his being subject to their direction.
    —Charles Louis de Secondat Montesquieu (1689–1755)

    Many of our houses, both public and private, with their almost innumerable apartments, their huge halls and their cellars for the storage of wines and other munitions of peace, appear to me extravagantly large for their inhabitants. They are so vast and magnificent that the latter seem to be only vermin which infest them.
    Henry David Thoreau (1817–1862)
