In the context of IBM PC compatible computers, extended memory refers to memory in the address space of the 80286 and subsequent processors, beyond the 1 megabyte limit imposed by the 20 address lines of the 8088 and 8086. Such memory is not directly available to PC DOS (MS DOS) applications running in the so-called "real mode" of the 80286 and subsequent processors. This memory is only accessible in the protected or virtual modes of 80286 and higher processors.

Famous quotes containing the words extended and/or memory:
“All the Valley quivered one extended motion, wind
undulating on mossy hills”
—Allen Ginsberg (b. 1926)
“I hope there will be no effort to put up a shaft or any monument of that sort in memory of me or of the other women who have given themselves to our work. The best kind of a memorial would be a school where girls could be taught everything useful that would help them to earn an honorable livelihood; where they could learn to do anything they were capable of, just as boys can. I would like to have lived to see such a school as that in every great city of the United States.”
—Susan B. Anthony (18201906)
