Discrete may refer to:
*Discrete particle or
quantum in physics, for example in quantum theory
*
Discrete device
An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are n ...
, an electronic component with just one circuit element, either passive or active, other than an integrated circuit
*
Discrete group
In mathematics, a topological group ''G'' is called a discrete group if there is no limit point in it (i.e., for each element in ''G'', there is a neighborhood which only contains that element). Equivalently, the group ''G'' is discrete if and o ...
, a group with the discrete topology
*
Discrete category, category whose only arrows are
identity arrows
*
Discrete mathematics
Discrete mathematics is the study of mathematical structures that can be considered "discrete" (in a way analogous to discrete variables, having a bijection with the set of natural numbers) rather than "continuous" (analogously to continu ...
, the study of structures without continuity
*
Discrete optimization
Discrete optimization is a branch of optimization in applied mathematics and computer science.
Scope
As opposed to continuous optimization, some or all of the variables used in a discrete mathematical program are restricted to be discrete var ...
, a branch of optimization in applied mathematics and computer science

Discrete probability distribution
In probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. It is a mathematical description of a random phenomenon i ...
, a random variable that can be counted
*
Discrete space
In topology, a discrete space is a particularly simple example of a topological space or similar structure, one in which the points form a , meaning they are ''isolated'' from each other in a certain sense. The discrete topology is the finest top ...
, a simple example of a topological space

Discrete spline interpolation In the mathematical field of numerical analysis, discrete spline interpolation is a form of interpolation where the interpolant is a special type of piecewise polynomial called a discrete spline. A discrete spline is a piecewise polynomial such tha ...
, the discrete analog of ordinary spline interpolation
*
Discrete time, non-continuous time, which results in discrete-time samples
*
Discrete variable, non-continuous variable
*Discrete
pitch, a pitch with a steady frequency, rather than an indiscrete gliding, glissando or portamento, pitch
