E-Business = a term
that is easily confused with E-Commerce. E-Business
may be an umbrella term that refers to any type
of business transaction on the Internet. Some
writers, however, may use the term in a more restricted
context such as a business-to-business (B2B) transaction
as opposed to a business-to-consumer (B2C) transaction.
For example, a B2B transaction might be a business
firm's online banking transaction. E-Commerce
refers more to the B2C context where a firm sells
goods on the internet and makes collections via
some payment scheme such as online credit card transactions.

ECCH =
European Case Clearing House,
Cranfield Institute of Technology, Beds, MK43 0AL,
United Kingdom (also at Babson College in Babson
Park, Wellesley, MA 02157). The ECCH now offers
an on line network server for international cases.
Although none of the cases are, as yet, in hypertext
or hypermedia format, it is a useful feature to
have cases available for file transfer on the Internet.
(See also HBSP)
E-Business =
(See E-Business).
Echo = return response
between a host server and a terminal computer.
It is generally coded to be "on" or "off."
If echo is "on" (full duplex), the host
will send back every character the user types in.
If echo is "off" (half duplex), the host
will not send back the characters, and the user's
local computer or terminal writes each character
to the screen directly. This can be confusing to
new users if the state of the echo parameter is
different on the host computer and the user's computer.
EDI = The abbreviation
for Electronic Data Interchange
or Electronic Data Invoicing. The EDI system allows
linked computers to conduct business transactions
such as ordering and invoicing over telecommunications
networks. The technology dates back to the 1970s
when the first attempts at setting uniform standards
commenced. However, EDI in telecommunications never
lived up to its expectations largely due to high
fees of Value Added Network (VAN) providers that,
prior to the Internet usage, charged both monthly
and transaction fees. In the late 1990s, EDI became
less costly (as low as 10% of former VAN costs)
when business applications exploded on the Internet
and in intranets. The ultimate goal of EDI is to
have standardized computer forms for business transactions
and networking of nearly all aspects business transactions.
This would greatly simplify use of networks to conduct
business, accounting for transactions, and auditing.
See "Intranets and Iternet: New Life for EDI,"
in Information Week, March 17, 1997, pp 65-67.
Gradually EDI is being taken over by extranet networks
on the Internet. See Extranet.
EDGAR = Electronic
Data Gathering, Analysis, and
Retrieval database of the Securities and Exchange Commission
(SEC). EDGAR contains the digitized
versions of many corporate filings, including 10Q
quarterly and 10K annual financial reports of registered
corporations and mutual funds.
The
EDGAR database is one probably the most widely used
database by investors and financial analysts.
The drawback is that many of the filings are very
long, sometimes exceeding 300 pages. Searching
is usually tedious and requires considerable financial
searching and accounting skills. Until filings
are marked up in XBRL,
the searching EDGAR will be tedious.
Currently,
there are some corporate Web sites to aid in searching
for EDGAR data. One of the best known is EDGAR
Online at http://www.edgar-online.com/.
EDGAR Online uses enhanced parsing technologies
to quickly extract the popular data most often sought
after by investors. Added services include
email alerts, multiple file formates, and spreadsheet
downloads. One of EDGAR Online's most popular
services is a sales lead geration product called
Wealth ID. This provides personal wealth information
about individuals who file SEC Form 144 regarding
sales of restricted stock.
Another
help site is called EDGAR Advantage at http://www.edgaradvantage.com/resources.htm
.This is more of a consulting site for EDGAR filers
than users.
Education grants = (See Funding)
EDUCOM = A group of cooperating colleges and universities dedicated
to advancing computer and network communications
technology in education. EDUCOM coordinates newsletters
and other publishing efforts along with conferences
and related activities. For free publication subscriptions,
contact EDUCOM, 1112
16th St. NW, Suite 600, Washington,
DC 20036
(202-872-4200).
EduQuest = A revitalized system of multimedia hardware and software
packages from IBM Corporation. The system primarily
targets the K-12 education system in the United States. The new system is designed to be
more powerful with networked PCs and a variety of
Plug and Play adapters for auxiliary components.
EISA =
(See Bus)
Electronic classroom = A large or small classroom filled with
multimedia devices. The usual context is that of
a lecture hall where the instructor has fingertip
control of multimedia aids such as computer images,
video tape images, videodisc images, audio, CD-ROM
players, Internet connections, cameras that transfer
images to large screens, etc. Some electronic classrooms
have student response hardware such as response
pads or even computer terminals. Usually, however,
the electronic classroom is not viewed in the same
context as a computer/multimedia lab or a language
lab. In a lab setting the student usually works
alone or in small teams in front of computers. In
an electronic classroom, the instructor is usually
focusing the attention of the entire class upon
the same learning media. However, labs can be equipped
with central screens so that combinations of instructor-focused
materials can be combined with individual learning.
Large lecture halls can also be equipped with students
who combine large lectures with "studio classroom
learning." See DeLoughry
(1995a). (See also Studio
classroom)
Electronic Jamming
(See Security)
E-mail or email = Electronic mail transmitted between millions
of users connected on networks worldwide. Messages
are exchanged instantaneously, usually at zero marginal
cost to users, thereby saving greatly on national
or international telephone and express mail fees.
Messages may be stored in computer files and processed
at a user's convenience. Precautionary advice
is given under ActiveX.

Emulation = (See Native)
Encryption = cryptographic conversion
of data into ciphertext in order to prevent any
but the intended recipient from reading that data.
There are many types of data encryption, and they
are the basis of network security. Common types
include Data Encryption Standard and public-key encryption.
(See Security)
eNetwork Software= (See IBM)
Enterprise= A synonym for business, mainly
big business. The enterprise computing market is
typically the corporations that buy hardware and
software and use them to run their operations.
EPG = Electronic
Program Guide that displays scheduled
shows on screen such as TV Guide On Screen.
ERP =
(See SAP).
ERIC =
Educational Resources Information
Center documents database that contains a variety of resources
to educators, especially teachers in K-12 schools.
(See also Telnet)
ESH = Electronic
Super Highway. (See Information
highway)
ERP =
(See SAP.)
Ethernet = A widely used interface data processing scheme for
managing data transfers on network. An ethernet
board (card) must be put into the computer for network
connections. It can network a wide variety of computers,
it is not proprietary, and components are widely
available from many commercial sources.
Evaluation = (See Assessment)
Event handler = A special
type of function that executes automatically when
a particular user-enabled, system-enabled, or code-generated
event occurs.
eWorld =
A commercial world-wide network launched by Apple
Corporation to compete with Interchange, CompuServe,
Prodigy, and America Online. Key features of eWorld
include its ease of use and graphical interface.
The major limitation is that its use is restricted
to Mac operating systems. A second drawback according
to Mossberg
(1994c) is that eWorld uses older
technology revised from America Online. (See also
Networks,
CompuServe,
Internet,
Prodigy,
Interchange,
and America
Online)
Execution flow = The section
of code that the application executes, depending
on branching decisions.
Expanded memory = (See RAM)

Expert systems = (See Artificial
Intelligence)
Explorer = (See Web browsers)
Express Author = A front
end to Asymetrix Multimedia ToolBook that performs
automatic scripting to both speed authoring and
aid ToolBook novices. The software was developed
at the IAT. This front end is mainly an aid to beginning
authors who do not plan to become ToolBook experts.
(See also Authoring
and IAT)
Extended memory = (See RAM)
eXstensible Style Language (XSL)
= (See HTML)
External Viewer = A program
used for presenting graphics, audio and video files.
Programs that allow the viewing of GIF and JPEG
files and the hearing of AU files fall into this
category.
Extractor = (See Wrapper).
Extranet = a term depicting networks on the Internet dedicated
to business communications between a vendor and
its suppliers, customers, or dealers. The term originated
from network pioneer Robert Metcalfe. Using the
common format of the World Wide Web, companies,
their suppliers, customers, or suppliers exchange
data electronically rather than sending paper-based
information back and forth. It is viewed as an Internet
alternative to Electronic Data Interchange comprised
of dedicated lines and software rather than the
Internet. Extranets are a lower cost alternative
to EDI. For example, see "Toshiba Debuts Extranet"
in Information Week, October 20, 1997, p. 36. Therein
it is stated that nearly all of Toshiba's 350 independent
dealers will be ordering products and parts via
a secure extranet. FedEx
now offers a BusinessLink extranet service with
intent on handling the accounting for transactions
as well as delivery of product. Competitors either
are or will soon offer similar extranets. See EDI,
Internet,
and Intranet.
