E-zine
|
Electronic
Magazines are short online journals written for the Internet that
take advantage of the low publishing cost of the World Wide Web. |
|
Easter
Egg
|
Programmers
sometimes put pieces of code into an application that produce
unexpected surprises. Users usually won't see them unless they
press a certain key combination. They're usually found by word
of mouth and rarely by accident. |
|
Edge Connector
|
Found
along one side of an expansion card, the little metal connectors
that transmit data and other signals to your computer through
the bus slot that it fits into. |
|
EDO RAM
|
Extended
Data Out RAM. A type of DRAM that can be 10% to 20% faster than
normal DRAM if no external cache is used. EDO keeps its chip output
buffer open longer and can begin to access more data even before
its done reading the previous data. Not much of a speed increase
is noticed over Fast Page Mode RAM if an external cache of 256K
is present. Controller must be compatible or it will act like
normal DRAM. |
|
EEPROM
|
Electronically
Erasable Programmable Read Only Memory. A type of ROM chip that
can be electronically erased and reprogrammed in circuit using
software. The introduction of EEPROM allowed expansion devices
to be configured using software instead of jumpers and DIP switches. |
|
EGA
|
Enhanced
Graphics Adapter. A high resolution video card that came out after
CGA. It was manufactured by IBM and could produce a resolution
of 640 X 350 pixels and display 16 colors out of a palette of
64. |
|
EIDE
|
Enhanced
Integrated Drive Electronics. Improved version of the IDE interface
for hard drives and CD-ROMs. EIDE uses Logical Block Addressing
which allows for HD capacities over 528 MB. It makes use of Direct
Memory Access and can address up to four devices. Also called
Fast ATA. |
|
EISA
|
Extended
Industry Standard Architecture. The standard for an IBM compatible
computer data bus that can transfer 32 bits of data at a time.
Extended ISA was developed in response to IBM's proprietary Micro
Channel Architecture bus (MCA). Unlike MCA, it was backwards compatible
with the older 16 bit ISA bus. |

Discharge

ESD. |
|
EMM386.EXE
|
A
DOS Extended Memory Manager utility that provides access to upper
memory blocks and can use Extended Memory to emulate Expanded
Memory for the older DOS programs that require it. |
|
Energy
Star Systems
|
Systems
that satisfy the EPA requirements to decrease the overall consumption
of electricity. "Green Systems". |
|
Enhanced
BIOS
|
A
newer BIOS that has been written to accommodate larger-capacity
(gigabyte) drives. |
|
Enhanced
Graphics Adapter
|
See
EGA. |
|
EPROM
|
Erasable
Programmable Read Only Memory. A type of PROM chip that can be
removed from the circuit and erased using ultraviolet light. The
chip can then be re-programmed using an EPROM burner. |
|
ESD
|
Electrostatic
Discharge is the discharge of built up static electricity. You
may not even feel the discharge but ESD can damage chips and ruin
motherboards, rendering your computer useless. |
|
Expansion
Card
|
An
electronic circuit board that fits into a slot on your motherboard
expanding the capabilities of your computer.
i.e.: video card, internal modem,
sound card.
|
|
Expansion
Slot
|
A
connector or slot on your computers motherboard that allows for
the insertion of an expansion card, connecting it to the systems
bus or electronic pathways. |
