- priority scheduling — (operating system) Processes scheduling in which the scheduler selects tasks to run based on their priority as opposed to, say, a simple round-robin. Priorities may be static or dynamic. Static priorities are assigned at the time of creation, while dynamic priorities are based on the processes' behaviour while in the system. For example, the scheduler may favour I/O-intensive tasks so that expensive requests can be issued as early as possible. A danger of priority scheduling is starvation, in which processes with lower priorities are not given the opportunity to run. In order to avoid starvation, in preemptive scheduling, the priority of a process is gradually reduced while it is running. Eventually, the priority of the running process will no longer be the highest, and the next process will start running. This method is called aging.

- raise one's hackles — one of the long, slender feathers on the neck or saddle of certain birds, as the domestic rooster, much used in making artificial flies for anglers.
- rayleigh scattering — the scattering of light by particles that are very small in relation to the wavelength of the light, and in which the intensity of the scattered light varies inversely with the fourth power of the wavelength.
- recessional moraine — a moraine marking a temporary halt in the general retreat of a glacier.
- reciprocal exchange — an unincorporated association formed so that its members can participate in reciprocal insurance.
- reciprocal leveling — leveling between two widely separated points in which observations are made in both directions to eliminate the effects of atmospheric refraction and the curvature of the earth.
- reconceptualization — to form into a concept; make a concept of.
- recurrence relation — (mathematics) An equation that defines each element of a sequence in terms of one or more earlier elements. E.g. The Fibonacci sequence, X[1] = 1 X[2] = 1 X[n] = X[n-1] + X[n-2] Some recurrence relations can be converted to "closed form" where X[n] is defined purely in terms of n, without reference to earlier elements.
- reduction potential — (in a galvanic cell) the potential of the electrode at which reduction occurs.
- register allocation — (compiler, algorithm) The phase of a compiler that determines which values will be placed in registers. Register allocation may be combined with register assignment. This problem can be shown to be isomorphic to graph colouring by relating values to nodes in the graph and registers to colours. Values (nodes) which must be valid simultaneously are linked by edges and cannot be stored in the same register (coloured the same). See also register dancing and register spilling.
- regression analysis — Statistics. a procedure for determining a relationship between a dependent variable, as predicted success in college, and an independent variable, as a score on a scholastic aptitude test, for a given population. The relationship is expressed as an equation for a line (regres·sion·line) or curve (regres·sion·curve) in which any coefficient (regression coefficient) of the independent variable in the equation has been determined from a sample population.
- regular icosahedron — an icosahedron in which each of the faces is an equilateral triangle
- reindustrialization — the revitalization of an industry or industrial society through government aid and tax incentives, modernization of factories and machinery, etc.
- relational calculus — (database) An operational methodolgy, founded on predicate calculus, dealing with descripitive expressions that are equivalent to the operations of relational algebra. Codd's reduction algorithm can convert from relational calculus to relational algebra. Two forms of the relational calculus exist: the tuple calculus and the domain calculus.
- relational database — an electronic database comprising multiple files of related information, usually stored in tables of rows (records) and columns (fields), and allowing a link to be established between separate files that have a matching field, as a column of invoice numbers, so that the two files can be queried simultaneously by the user.
- relational language — (language) Any kind of programming language that specifies output in terms of some property and some arguments. For example, if Tom has two brothers, Dick and Harry, a relational language will respond to the query "Who is Tom's brother?" with either Dick or Harry. Notice that unlike functional languages, relational languages do not require a unique output for each predicate/argument pair. Prolog is the best known relational language.
- relative complement — the set of elements contained in a given set that are not elements of another specified set.
- relative impediment — a fact or circumstance that disqualifies from lawful marriage persons who are closely related.
- releasing mechanism — a hypothetical control complex in the central nervous system of animals that triggers the appropriate behavioral response to a releaser.

- religious education — religion as school subject
- relocation expenses — Relocation expenses are a sum of money that a company pays to someone who moves to a new area in order to work for the company. The money is to help them pay for moving house.
