EBCDIC :
Extended Binary Coded Decimal Interchange Code. IBM specific
code mapping characters on an 8 bit format.
ECC :
Error Correcting Code. The diagnostic code used to correct
data storage errors and to isolate hardware failures. Based on
a concept of simultaneous polynomial equations, the read-back
process generates a "correction" profile that is
exclusive-OR'ed over the incorrect data. All ECCs have a very
small, but finite failure rate; that is, some uncorrectable
errors will either appear as correctable or appear as having
no error at all. In either situation, bad data is passed as
verified and valid.
ECMA :
European Computer Manufacturers Association. Develops
standards for submission to International Standards
Organization.
EDI :
Electronic Data Interchange. The electronic transfer of
preformatted business documents, such as purchase orders and
bills of lading, between trading partners.
EDIFACT :
Electronic Data Interchange for Administration, Commerce and
Transportation. An EDI standards development group.
EGA :
Enhanced Graphic Adapter. Ancient video standard allowing
graphical color display ( resolution 640x340 in monochrome).
EIA :
Electronic Industries Association, in charge of defining norms
in the USA.
EISA :
Extended Industry Standard Architecture. This is an extension
of the standard ISA bus interface, which specifies on personal
computers (PC compatible) the physical and logical
characteristics of the interface. EISA has a 32 bit-wide
interface. An EISA slot can also be used for an 8 or 16 bit
ISA PCB.
E-Mail (Electronic Mail) :
Software allowing to compose, transmit and receive messages
and attached/enclosed files.
Emulation :
Mode in which a system imitates another one in order to
exploit the same programs or to provide the same results.
Emulation facilitates conversion.
Energy Star :
Norm defined by the EPA (US Environment Protection Agency) for
computer manufacturers aiming at reducing electrical
consumption.
Error control :
Strategy implemented in software, hardware or procedures for
detecting and possibly correcting the errors happening in a
communication system.
ESDI :
Enhanced Small Device Interface. Disk connection interface.
The SDSI standard is replacing ESDI.
Ethernet :
A base band local-area network developed by Xerox Corp. It has
a bus topology with Carrier Sense Multiple Access/Collision
Detection access control. An Ethernet network provides a raw
10 Mbps, with an effective throughput around 2-3 Mbps.
Ethernet networks characteristics are defined in norm IEEE
802.3.
Excel :
Microsoft spreadsheet.
Expert System :
A software system with two basic components: a knowledge base
and an inference engine. The system mimics an expert's
reasoning process.
Extranet :
An intranet that is accessible to computers that are
not physically part of a company's' own private network,
but that is not accessible to the general public, for example
to allow vendors and business partners to access a company web
site.
Often an intranet will make use of a Virtual Private Network.
