ESM
Abbreviation for Embedded Systems Management.
expanded memory
A technique for accessing RAM above 1 MB. To enable expanded memory on
your computer, you must use an EMM. You should configure your system to
support expanded memory only if you run application programs that can use (or
require) expanded memory.
expansion bus
Your computer contains an expansion bus that allows the microprocessor to
communicate with controllers for peripheral devices, such as a network card or
an internal modem.
expansion-card connector
A connector on the computer’s system board or riser board for plugging in an
expansion card.
extended memory
RAM above 1 MB. Most software that can use it, such as the Windows operating
system, requires that extended memory be under the control of an XMM.
external cache memory
A RAM cache using SRAM chips. Because SRAM chips operate at several times
the speed of DRAM chips, the microprocessor can retrieve data and instructions
faster from external cache memory than from RAM.
