- electronic mail address — (messaging) (Usually "e-mail address") The string used to specify the source or destination of an electronic mail message. E.g. "[email protected]". The RFC 822 standard is probably the most widely used on the Internet. X.400 was once used in Europe and Canada. UUCP-style (bang path) addresses or other kinds of source route became virtually extinct in the 1990s. In the example above, "john" is the local part which is the name of a mailbox on the destination computer. If the sender and recipient use the same computer, or the same LAN, for electronic mail then the local part is usually all that is required. If they use different computers, e.g. they work at different companies or use different Internet service providers, then the "host part", e.g. "sales.acme.com" must be appended after an "@". This usually takes the form of a fully qualified domain name or, within a large organisation, it may be just the hostname part, e.g. "sales". The destination computer named by the host part is usually a server of some kind rather than an individual's workstation or PC. The user's mail is stored on the server and read later via client mail software running on the user's computer. Large organisations, such as universities will often set up a global alias directory which maps a simple user name such as "jsmith" to an address which contains more information such as "[email protected]". This hides the detailed knowledge of where the message will be delivered from the sender, making it much easier to redirect mail if a user leaves or moves to a different department for example.
- electronic surveillance — use of electronic devices to spy, observe
- electrophotographically — In an electrophotographic manner; by means of electrophotography.
- electrostatic discharge — (hardware, testing) (ESD) One kind of test that hardware usually has to pass to prove it is suitable for sale and use. The hardware must still work after is has been subjected to some level of electrostatic discharge. Some organisations have their own ESD requirements which hardware must meet before it will be considered for purchase. Different countries have different legal regulations about levels of ESD. See also Radio Frequency Interference, Electromagnetic Compatibility.
- electrostatic generator — any device for producing a high voltage by building up a charge of static electricity
- electroweak interaction — a type of fundamental interaction combining both the electromagnetic interaction and the weak interaction
- eliminative materialism — (in philosophy of mind) the theory that people's common-sense understanding of the mind is false and that certain classes of mental states that most people believe in do not exist
- encapsulated postscript — (EPS) An extension of the PostScript graphics file format developed by Adobe Systems. EPS is used for PostScript graphics files that are to be incorporated into other documents. An EPS file includes pragmas (special PostScript comments) giving information such as the bounding box, page number and fonts used. On some computers, EPS files include a low resolution version of the PostScript image. On the Macintosh this is in PICT format, while on the IBM PC it is in TIFF or Microsoft Windows metafile format.

- fully associative cache — (memory management) A type of cache in which data from any address can be stored in any cache location. The whole address must be used as the tag (the value that identifies a block of data in the cache). All tags must be compared simultaneously (associatively) with the requested address and if one matches then its associated data is accessed. This requires an associative memory to hold the tags which makes this form of cache more expensive. It does however solve the problem of contention for cache locations (cache conflict) since a block need only be flushed when the whole cache is full and then the block to flush can be selected in a more efficient way. The alternatives are direct mapped cache or set associative cache.
- function graph language — (language) (FGL) The machine language for the AMPS (Applicative Multi-Processing System) proposed by Robert Keller, Gary Lindstrom and Suhas Patil at the University of Utah.
- functional requirements — (specification) What a system should be able to do, the functions it should perform. This term is used at both the user requirements analysis and software requirements specifications phases in the software life-cycle. An example of a non-functional requirement is an initialisation sequence incorporated into the software that is specific to a given customer.
- fundamental interaction — any of the four basic interactions that occur in nature: the gravitational, electromagnetic, strong, and weak interactions
