- EAP (Extensible Authentication Protocol)
An extension of the PPP protocol that supports authentication methods more secure than a standard username and password combination. EAP is commonly used as an authentication protocol for token cards, smart cards, and digital certificates.
- EMI (electromagnetic interference)
External interference of electromagnetic signals that causes a reduction of data integrity and increased error rates in a transmission medium.
- encapsulation
A technique used by protocols in which header and/or trailer information is added to the protocol data unit as it is passed down through the protocol stack on a sending system. The reverse process, called decapsulation, is performed at the receiving system as the packet travels up through the protocol suite.
- encryption
The modification of data for security purposes prior to transmission so that it is not comprehendible without the decoding method.
- ESD (electrostatic discharge)
A condition that is created when two objects of dissimilar electrical charge come into contact with each other. The result is that a charge from the object with the higher electrical charge discharges itself into the object with the lower-level charge. This discharge can be extremely harmful to computer components and circuit boards.
- Ethernet
The most common LAN technology. Ethernet can be implemented using coaxial, twisted-pair, or fiber-optic cable. Ethernet typically uses the CSMA/CD media access method and has various implementation standards.
- Event Viewer
A utility that facilitates the viewing of log files on Windows server operating systems.
- EXT2
