[common] To copy a large array of bits from one part of a

computer's memory to another part, particularly when the memory is being
|

used to determine what is shown on a display screen. “<span class="quote">The storage

allocator picks through the table and copies the good parts up into high

memory, and then blits it all back down again.</span>” See

designed by Rob Pike at Bell Labs, later commercialized as the AT&T

5620. (The folk etymology from “<span class="quote">Bell Labs Intelligent

“<span class="quote">Blit</span>” stood for the Bacon, Lettuce, and Interactive
