Computer Multitasking - Real Time

Real Time

Another reason for multitasking was in the design of real-time computing systems, where there are a number of possibly unrelated external activities needed to be controlled by a single processor system. In such systems a hierarchical interrupt system is coupled with process prioritization to ensure that key activities were given a greater share of available process time.

Famous quotes containing the words real and/or time:

    “... there is a place in the United States for the Negro. They are real American citizens, and at home. They have fought and bled and died, like men, to make this country what it is. And if they have got to suffer and die, and be lynched, and tortured, and burned at the stake, I say they are at home.”
    —Amanda Berry Smith (1837–1915)

    “We talked of the education of children; and I asked him what he thought was best to teach them first. JOHNSON. “Sir, it is no matter what you teach them first, any more than what leg you shall put into your breeches first. Sir, you may stand disputing which is best to put in first, but in the mean time your breech is bare. Sir, while you are considering which of two things you should teach your child first, another boy has learnt them both.”
    —Samuel Johnson (1709–1784)
