diskrit

Diskrit is a term used in mathematics, computer science, and related fields to describe objects that consist of distinct, separate values or elements. The word is derived from Latin discretus, meaning separated, and is used in Indonesian as the equivalent of the English "discrete." In contrast to continuous concepts, which can take any value within an interval, discrete entities have countable, separate values.

In practice, diskrit refers to structures such as finite or countably infinite sets, integers, rational numbers with restricted domains, Boolean values, and graphs. Discrete time models progress in steps, not smoothly. Discrete mathematics studies these objects and their properties, including combinatorics, graph theory, number theory, automata theory, and discrete probability. The notion is fundamental to computer science, where data and processes are often modeled discretely.

Examples include representing a street network as a graph of intersections (nodes) and roads (edges), counting the number of users, or storing data in discrete units like bits. In signal processing, discrete signals are obtained by sampling continuous signals at regular intervals.

Applications span algorithms, cryptography, coding theory, database theory, and network analysis. While discrete models can approximate real-world continuous phenomena, they emphasize distinct values and stepwise change rather than smooth variation. The term diskrit is often used interchangeably with discrete, especially in Indonesian-language texts and education.
