the referencing program at the time it is loaded into
memory.
DMA

that is characterized by extremely high density, low power,
and low cost. It must be more or less continuously refreshed
to avoid loss of data.

EEPROM
E lectrically E rasable P rogrammable R ead- O nly M emory. A
memory storage device that can be written repeatedly with
no special erasure fixture. EEPROMs do not lose their
contents when they are powered down.
EISA (bus)
E xtended I ndustry S tandard A rchitecture (bus) (IBM). An
architectural system using a 32-bit bus that allows data to be
transferred between peripherals in 32-bit chunks instead of
the 16-bit or 8-bit units that most systems use. With the
transfer of larger bits of information, the machine is able to
perform much faster than the standard ISA bus system.
