Operating instructions

EEPROM (electrically erasable programmable read-only memory) Atypeof
ROM chip that can be erased and reprogrammed electrically. EEPROMs were
the most common storage device for BIOS before the advent of Flash ROM.
EFS (encrypting file system) The encryption tool found in NTFS 5.
EIA/TIA See TIA/EIA.
EIDE (enhanced IDE) A marketing concept of hard drive–maker Western
Digital, encompassing four improvements for IDE drives. These improvements
included drives larger than 528 MB, four devices, increase in drive throughput,
and non–hard drive devices. See also ATAPI, PIO.
EISA (enhanced ISA) An improved expansion bus, based on the ISA bus,
with a top speed of 8.33 MHz, a 32-bit data path, and a high degree of self-
configuration. Backward compatible with legacy ISA cards.
e-mail, email (electronic mail) Messages, usually text, sent from one person
to another via computer. E-mail can also be sent automatically to a group of
addresses (mailing list).
EMI (electro-magnetic interference) EMI is electrical interference from one
device to another, resulting in poor performance of the device being interfered
with. An example is having static on your TV while running a blow dryer, or
placing two monitors too close together and getting a “shaky” screen.
EPROM (erasable programmable read-only memory) A special form of ROM
that can be erased by high-intensity ultraviolet light and then rewritten (repro
-
grammed).
ERD (emergency repair disk) This disk saves critical boot files and partition
information and is the main tool for fixing boot problems in Windows 2000.
ESD (electrostatic discharge) The movement of electrons from one body to
another. ESD is a real menace to PCs, as it can cause permanent damage to semi
-
conductors.
Ethernet Name coined by Xerox for the first standard of network cabling and
protocols. Ethernet is based on a bus topology.
EULA (end user license agreement) An agreement that accompanies a piece
of software, which the user must agree to in order to use the software. This
