EAP

Extensible Authentication Protocol, an extension to PPP. EAP is a general protocol for authentication that also supports multiple authentication methods.

EBCDIC

Extended Binary-Coded Decimal Interchange Code. EBCDIC is an IBM code for representing characters as numbers. Although it is widely used on large IBM computer, most other computers, including PC and Macintoshes, use ASCII codes.

EBT

Electronic Benifits Transfer. An e-commerce process that allows instantaneous payment of benifits to employee and corporate bank accounts.

ECC

Error Correction Code, is used for controlling errors in data over unreliable or noisy communication channels.

ECML

Electronic Commerce Modeling Language. ECML is a universal format for online commerce Web sites that contains customer information that is used for purchases made online, formatted through the use of XML tags. It is a standard way of transferring billing, shipping and payment information to merchant sites regardless of what site the customer is purchasing from. If order forms are standardised, the customer's information can be imported directly into the form from a digital wallet with the click of one button. This saves the customer from repeatedly filling out the same information on multiple order forms on multiple sites. ECML can be used in conjunction with SSL and SET.

ECP

Extended Capabilities Port, a parallel-port standard for PCs that supports bi-directional communication between the PC and attached devices (such as a printer). ECP is about 10 times faster than the older Centronics standard. Another modern parallel port for PCs that offers similar performance is the EPP.

EDGE

Enhanced Data GSM Environment, is a faster version of GSM wireless service. It enables data to be delivered at rates up to 384 Kbps on a broadband. It uses TDMA multiplexing technology and the standard is based on GSM.

EDI

Electronic Data Interchange, the transfer of data between different companies using networks, such as the Internet. As more and more companies get connected to the Internet, EDI is becoming increasingly important as an easy mechanism for companies to buy, sell, and trade information. ANSI has approved a set of EDI standards known as the X12 standards.

EDO-DRAM

Extended Data Output Dynamic Random Access Memory, a type of DRAM that is faster than conventional DRAM. Unlike conventional DRAM which can only access one block of data at a time, EDO RAM can start fetching the next block of memory at the same time that it sends the previous block to the CPU.

EDR

Endpoint Detection and Response, is an integrated, layered approach to endpoint protection that combines real-time continuous monitoring and endpoint data analytics with rule-based automated response.

EDSFF

Enterprise & Data Center SSD Form Factor.

EEPROM

Electrically Erasable Programmable Read-Only Memory. An EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge. Like other types of PROM, EEPROM retains its contents even when the power is turned off. Also like other types of ROM, EEPROM is not as fast as RAM. EEPROM is similar to flash memory (sometimes called flash EEPROM). The principal difference is that EEPROM requires data to be written or erased one byte at a time whereas flash memory allows data to be written or erased in blocks.

EFS

Encrypting File System. It is part of the Microsoft NTFS file system. EFS is a transparent public key encryption technology that works in conjunction with NTFS permissions to grant and deny users access to files and folders in Windows NT, 2000 and XP operating systems.

EFT

Electronic Funds Transfer.

EHR

Electronic Health Record.

EIDE

Enhanced IDE, a newer version of the IDE mass storage device interface standard. It supports data rates of between 4 and 16.6 MBps, about three to four times faster than the old IDE standard. In addition, it can support mass storage devices of up to 8.4 Gb, whereas the old standard was limited to 528 MB. Because of its lower cost, enhanced IDE has replaced SCSI in many areas. EIDE is sometimes referred to as Fast ATA or Fast IDE, which is essentially the same standard. It is also sometimes called ATA-2. There are four EIDE modes defined. The most common is Mode 4, which supports transfer rates of 16.6 MBps. There is also a new mode, called ATA-3 or Ultra ATA, that supports transfer rates of 33 MBps.

EJB

Enterprise JavaBean is a Java API that defines a component architecture for multi-tier client/server systems. EJB systems allow developers to focus on the actual business architecture of the model, rather than worry about endless amounts of programming and coding needed to connect all the working parts. This task is left to EJB server vendors. Developers just design (or purchase) the needed EJB components and arrange them on the server. Because EJB systems are written in Java, they are platform independent. Being object oriented, they can be implemented into existed systems with little or no recompiling and configuring.

ELAP

EtherTalk Link Access Protocol. In an EtherTalk network, the link-access protocol constructed above the standard Ethernet Data Link layer.

Elevator Pitch

A speech promoting a dot.com idea which lasts no longer than an elevator ride.

Elixir

Elixir is a functional, concurrent, general-purpose programming language that runs on the Erlang virtual machine.

Emoticons

An acronym for emotion icon, a small icon composed of punctuation characters that indicates how an e-mail message should be interpreted (that is, the writer's mood).
An emoticon is also called a smiley.

EPOC

An operating system from Psion Software, designed specifically for mobile, ROM-based computing devices. EPOC16 is a 16-bit version of the operating system that has been available for several years and is embedded in many handheld devices. EPOC32 is a newer, 32-bit operating system that supports preemptive multitasking. EPOC is competing head-to-head with Windows CE in the grow PDA market.

EPP

Enhanced Parallel Port, a parallel port standard for PCs that supports bi-directional communication between the PC and attached non-printer devices. EPP is about 10 times faster than the older Centronics standard. Another modern parallel port for PCs that offers similar performance is the ECP.

ERM

Enterprise Relationship Management, relates to solutions allowing an enterprise to share customer, product, competitor and market information to accomplish goals of meeting long-term customer satisfaction and increased revenues.

ERP

Enterprise Resource Planning. A business management system that integrates all facets of the business, including planning, manufacturing, sales, and marketing. As the ERP methodology has become more popular, software applications have emerged to help business managers implement ERP.

ESB

Enterprise Service Bus, is an open standards-based distributed synchronous or asynchronous messaging middleware that provides secure interoperability.

ESDI

Enhanced Small Device Interface, an interface standard developed by a consortium of the leading personal computer manufacturers for connecting disk drives to PCs. It is already obsolete.

ESP

Encapsulated PostScript. An extension of the PostScript graphics file format.

Ethernet

A LAN architecture developed in 1976. Ethernet uses a bus or star topology and supports data transfer rates of 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards. A newer version of Ethernet, called 100Base-T (or Fast Ethernet), supports data transfer rates of 100 Mbps. And the newest version, Gigabit Ethernet supports data rates of 1 gigabit (1,000 megabits) per second.

EtherTalk

A data-link product from Apple Computer that permits AppleTalk networks to be connected by Ethernet.

ETSI

European Telecommunications Standards Institute.

EULA

End-User License Agreement. The type of license used for most software.

Exabyte

A measurement of 2 to the power 60 bytes or 1024 petabytes.

Extranet

A new buzzword that refers to an intranet that is partially accessible to authorized outsiders. Whereas an intranet resides behind a firewall and is accessible only to people who are members of the same company or organization, an extranet provides various levels of accessibility to outsiders. You can access an extranet only if you have a valid username and password, and your identity determines which parts of the extranet you can view.
Extranets are becoming a very popular means for business partners to exchange information.
