EBOOK: An electronic
(usually hand-held) reading device that allows a person to view digitally
stored reading materials.
EBCDIC: Extended Binary
Coded Decimal Interchange Code. It is also called the Extended ASCII Code, as
it adds an eighth digit to the normal sevendigit code.
EDITOR: A program for
preparing and/or modifying a SOURCE PROGRAM or other file by addition,
deletion, or change.
E-COMMERCE: It means buying
or selling any product online using the internet technology. Many companies
have set up their web sites which provide the facilities to order and purchase
their products and services online.
E-MAIL: (Electronic
mail) Messages transmitted over the Internet from user to user. E-mail can

expression when viewed with your head tilted to the left. Here are some
examples:
:-) Smiling
:-( Frowning
;-) Winking
:_( Crying
EMITTER-COUPLED
LOGIC (ECL): A bipolar monolithic IC logic gate family
characterized by very high speed operation and relatively high power
dissipation compared with other monolithic IC logic families.
EMULATION: The process of
imitation (simulation) of one computer system by another. The imitating
program, or device (emulator), accepts the same data, executes the same
programs, and achieves the same results.
ENGINE: (as in “Search

ENCRYPTION: The process of
transmitting scrambled data so that only authorized recipients can unscramble

non-volatile, semiconductor memory that can be programmed, erased, and
reprogrammed many times without damage to the device.
ETHERNET: This is a
method of file transfer that uses dedicated cables rather than dial up phone

EVENT: An occurrence
