Expanded Memory (EMS) defines a 64K page frame in
the area between 640K and 1Mb containing four 16K pages
that are windows into the EMS memory. Programs issue
requests to the EMS manager to switch the page to any
part of EMS memory. Extended memory can be converted
to emulate EMS by using a memory manager such as
EMM386 that ships with Windows and DOS.

This refers to memory located in the 640K to 1024K ad-
dress space.  This  memory  can be used for different
applications.  DOS uses this area to load device drivers to
keep as much conventional memory free for application
programs as possible.
