- entity-relationship model — (database, specification) An approach to data modelling proposed by P. Chen in 1976. The model says that you divide your database in two logical parts, entities (e.g. "customer", "product") and relations ("buys", "pays for"). One of the first activities in specifying an application is defining the entities involved and their relationships, e.g. using an entity-relationship diagram to represent a model.

- frame relay access device — (communications) (FRAD) Hardware and software that turns packets from TCP, SNA, IPX, etc into frames that can be sent over a Frame Relay wide area network. FRADs are a hot topic in data comms because companies like Netlink, Motorola, Stratacom are making lots of money out of them.
- frequently asked question — (convention) (FAQ, or rarely FAQL, FAQ list) A document provided for many Usenet newsgroups (and, more recently, web services) which attempts to answer questions which new readers often ask. These are maintained by volunteers and posted regularly to the newsgroup. You should always consult the FAQ list for a group before posting to it in case your question or point is common knowledge. The collection of all FAQ lists is one of the most precious and remarkable resources on the Internet. It contains a huge wealth of up-to-date expert knowledge on many subjects of common interest. Accuracy of the information is greatly assisted by its frequent exposure to criticism by an interested, and occasionally well-informed, audience (the readers of the relevant newsgroup). The main FTP archive for FAQs is on a computer called RTFM at MIT, where they can be accessed either by group or by hierarchy. There is another archive at Imperial College, London, UK and a web archive in Ohio, USA. The FAQs are also posted to Usenet newsgroups: news:comp.answers, news:news.answers and news:alt.answers.
- fully booked/booked solid — If a hotel, restaurant, theatre, or transport service is fully booked, or booked solid, it is booked up.
- fully lazy lambda lifting — John Hughes's optimisation of lambda lifting to give full laziness. Maximal free expressions are shared to minimise the amount of recalculation. Each inner sub-expression is replaced by a function of its maximal free expressions (expressions not containing any bound variable) applied to those expressions. E.g. f = \ x . (\ y . (+) (sqrt x) y) ((+) (sqrt x)) is a maximal free expression in (\ y . (+) (sqrt x) y) so this inner abstraction is replaced with (\ g . \ y . g y) ((+) (sqrt x)) Now, if a partial application of f is shared, the result of evaluating (sqrt x) will also be shared rather than re-evaluated on each application of f. As Chin notes, the same benefit could be achieved without introducing the new higher-order function, g, if we just extracted out (sqrt x). This is similar to the code motion optimisation in procedural languages where constant expressions are moved outside a loop or procedure.

- graphic display interface — (hardware) (GDI) graphics adaptor.
- group-sweeping scheduling — (storage, algorithm) (GSS) A disk scheduling strategy in which requests are served in cycles, in a round-robin manner. To reduce disk arm movements ("seeking"), the set of streams is divided into groups that are served in fixed order. Streams within a group are served according to "SCAN". If all clients are assigned to one group, GSS reduces to SCAN, and if all clients are assigned to separate groups, GSS effectively becomes round-robin scheduling. The service order within one group is not fixed, and a stream may in fact be first in one cycle while last in the next. This variation has to be masked by extra buffering but whereas SCAN requires buffer space for all streams, GSS can reuse the buffer for each group and effect a trade-off between seek optimisation and buffer requirements.
