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:
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
“At about that time I was once sitting at my place and whispering—it was naughty, I know—with my neighbor. Then you, Herr Professor Rudner, got up from your desk, came calmly down the aisle to me: “Did you speak?” and slapped me smack in the face. And I—the fury is inside me to this day—I didn’t hit back. Such were the methods of objectivity.”
—Alfred Döblin (1878–1957)
