E-1 circuit: A large bandwidth phone connection. An E-1 circuit (2,000,000 bits per second) is the European equivalent (roughly speaking) of a T-1.
editor: a program designed for entering and manipulating text via a keyboard.
Electronic Frontier Foundation (EFF): A foundation established to address social and legal issues arising from the impact on society of the increasingly pervasive use of computers as a means of communication and information distribution. You can reach the EFF at info@eff~org. The EFF's anonymous F'I'P archive of user policies at schools and universities is particularly useftil.
e-mail (electronic mail): A system whereby a computer user can exchange messages with other computer users (or groups of users) via a communications network. Electronic mail is one of the most popular uses of the Internet.
e-mail address: The domain-based or UUCP address that is used to send electronic mail to a specified destination. For example, Bill Clinton's address is president@whitehouse.gov. See also UNIX-to-UNIX Copy.
encapsulation: The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer above. As an example, in Internet terminology; a packet would contain a header from the physical layer, followed by a header from the network layer (IP), followed by a header from the transport layer (TCP), followed by the application protocol data.
encryption: The manipulation of a packet's data in order to prevent any but the intended recipient from reading that data. There are many types of data encryption, which make up the basis of network security. See also Data Encryption Standard, Kerberos.
Ethernet: A local area network (LAN) transport protocol (TP), initially developed by Xerox and later refined by Digital, Intel, and Xerox IX.. It is very common in computer networks. It's bandwidth is 10 megabit (10,000,000 bits per second). All hosts are connected to a coaxial cable where they contend for network access using a Carrier Sense Multiple Access with Collision Detection (CSMA/C paradigm). See also Local Area Network.
Ethernet Address: sequence of numbers that is coded into the hardware of the Ethernet device, as opposed to the IP address which is assigned by the bootp server or other methods.
Ethernet cable: a cable capable of transmitting Ethernet signals most frequently 10baseT (looks like telephone wiring) and 10base2 (also called Thin Coax and looks like TV cable wiring).
Ethernet card: a piece of computer hardware that allows computers to exchange information by sending electrical signals through Ethernet cable.
Eudora: A freeware Windows-based E-mail utility often provided by ISP's It can he used to send and receive mail across the Internet via a SLIP or PPP account.
