As part of the
IBM PC compatible system architecture, originally only the first 640KB of memory was available for
application programs. Various schemes were used to make the rest of the first 1MB of memory and later memory beyond the 1MB boundary available to user programs. These schemes were superseded by virtual memory, demand paging
operating systems that made use of 32bit addressing capabilities that were introduced in the
Intel 80386 processor.
