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:
“A man’s real faith is never contained in his creed, nor is his creed an article of his faith. The last is never adopted. This it is that permits him to smile ever, and to live even as bravely as he does. And yet he clings anxiously to his creed, as to a straw, thinking that that does him good service because his sheet anchor does not drag.”
—Henry David Thoreau (1817–1862)
“And now in one hour’s time I’ll be out there again. I’ll raise my eyes and look down that corridor four feet wide with ten lonely seconds to justify my whole existence.”
—Colin Welland (b. 1934)
