- epsilon squared — (jargon) A quantity even smaller than epsilon, as small in comparison to epsilon as epsilon is to something normal; completely negligible. If you buy a supercomputer for a million dollars, the cost of the thousand-dollar terminal to go with it is epsilon, and the cost of the ten-dollar cable to connect them is epsilon squared. Compare lost in the underflow, lost in the noise.
- ergatandromorph — an ant with the characteristics of both worker and male
- eric conspiracy — (person, humour) A shadowy group of moustachioed hackers named Eric first pinpointed as a sinister conspiracy by an infamous talk.bizarre posting ca. 1986. This was doubtless influenced by the numerous "Eric" jokes in the Monty Python oeuvre. There do indeed seem to be considerably more moustachioed Erics in hackerdom than the frequency of these three traits can account for unless they are correlated in some arcane way. Well-known examples include Eric Allman (of the "Allman style" described under indent style), Erik Fair (co-author of NNTP), Eric S. Raymond and about fifteen others. The organisation line "Eric Conspiracy Secret Laboratories" now emanates regularly from more than one site.
- escape velocity — great enough speed to escape gravity
- esprit de corps — military, sport: team spirit
- ethnopsychology — The scientific study of psychological concepts as they exist across different ethnic groups.
- evaporated milk — concentrated dairy product
- exceptionalness — The quality of being exceptional.
- exemplification — The act of exemplifying; a showing or illustrating by example.
- existence proof — non-constructive proof
- expanded memory — (storage) Memory used through EMS. In systems based on Intel 80386 or later processor expanded memory is part of the extended memory that is mapped into the expanded memory page frame by the processor. The mapping is controlled by the EMM. In earlier systems, a dedicated EMS hardware adaptor is needed to map memory into the page frame. In both cases, an appropriate device driver is needed for the proper communication between hardware and EMM.
- expansion joint — structural feature: gap to allow for expansion or contraction
- expeditiousness — The state of being expeditious; celerity, rapidity or speed.
- expense account — account for expenses
- experimentation — The act of experimenting; practice by experiment.

- express oneself — to communicate one's thoughts or ideas

- fallopian tubes — one of a pair of long, slender ducts in the female abdomen that transport ova from the ovary to the uterus and, in fertilization, transport sperm cells from the uterus to the released ova; the oviduct of higher mammals.
- fatal exception — (programming, operating system) A program execution error which is trapped by the operating system and which results in abrupt termination of the program. It may be possible for the program to catch some such errors, e.g. a floating point underflow; others, such as an invalid memory access (an attempt to write to read-only memory or an attempt to read memory outside of the program's address space), may always cause control to pass to the operating system without allowing the program an opportunity to handle the error. The details depend on the language's run-time system and the operating system. See also: fatal error.
- fencepost error — 1. (Rarely "lamp-post error") A problem with the discrete equivalent of a boundary condition, often exhibited in programs by iterative loops. From the following problem: "If you build a fence 100 feet long with posts 10 feet apart, how many posts do you need?" (Either 9 or 11 is a better answer than the obvious 10). For example, suppose you have a long list or array of items, and want to process items m through n; how many items are there? The obvious answer is n - m, but that is off by one; the right answer is n - m + 1. The "obvious" formula exhibits a fencepost error. See also zeroth and note that not all off-by-one errors are fencepost errors. The game of Musical Chairs involves a catastrophic off-by-one error where N people try to sit in N - 1 chairs, but it's not a fencepost error. Fencepost errors come from counting things rather than the spaces between them, or vice versa, or by neglecting to consider whether one should count one or both ends of a row. 2. (Rare) An error induced by unexpected regularities in input values, which can (for instance) completely thwart a theoretically efficient binary tree or hash coding implementation. The error here involves the difference between expected and worst case behaviours of an algorithm.
- file descriptor — (programming, operating system) An integer that identifies an open file within a process. This number is obtained as a result of opening a file. Operations which read, write, or close a file would take the file descriptor as an input parameter. In many operating system implementations, file descriptors are small integers which index a table of open files. In Unix, file descriptors 0, 1 and 2 correspond to the standard input, standard output and standard error files respectively. See file descriptor leak.
- finance company — an institution engaged in such specialized forms of financing as purchasing accounts receivable, extending credit to retailers and manufacturers, discounting installment contracts, and granting loans with goods as security.
- finger-pointing — the imputation of blame or responsibility.
- fire prevention — safety measures to decrease fire risk
- fire water pond — A fire water pond is an area of water which is kept so it can be used if there is a fire.
- first responder — a person who is certified to provide medical care in emergencies before more highly trained medical personnel arrive on the scene: a firefighter trained as a first responder.
- fissiparousness — The quality of being fissiparous.
- flange coupling — a driving coupling between rotating shafts that consists of flanges (or half couplings) one of which is fixed at the end of each shaft, the two flanges being bolted together with a ring of bolts to complete the drive
- flapping router — (networking) A router that transmits routing updates alternately advertising a destination network first via one route, then via a different route. Flapping routers are identified on more advanced protocol analysers such as the Network General (TM) Sniffer.
