Discrete refers to something that is separate, distinct, or individual. In mathematics and statistics, discrete data refers to data that can only take on specific values and cannot be measured on a continuous scale.

Discrete refers to something that is separated or distinct into individual units or parts that are not continuous. It is often contrasted with the term "continuous," which describes something that is unbroken or flows smoothly without clear divisions.
Characteristics of Discrete Phenomena:
- Separateness: Discrete items are clearly distinguishable from one another and have distinct boundaries.
- Counting: Discrete quantities can be counted or measured in whole numbers.
- Finite or Countable: Discrete objects or values have a finite or countable number, meaning they can be listed or counted one by one.
- Non-reducible: Discrete units cannot be subdivided into smaller units without changing their nature.
Examples of Discrete Phenomena:
- Natural numbers (1, 2, 3, ...): Each number is a separate entity with no fractional values between them.
- Objects in a collection: A collection of objects, such as coins or books, can be counted and are distinct from one another.
- Pixels on a computer screen: Pixels are discrete squares that make up the image on a screen.
- Digital data: Computer data is stored in discrete bits (0s and 1s) that represent information.
Contrast with Continuous:
- Continuous phenomena are characterized by smoothly varying values or gradations, without clear divisions.
- Examples include temperature, light intensity, and the height of a liquid in a container.
Applications:
The concept of discrete is widely used in various fields, including:
- Mathematics: Discrete mathematics deals with counting, graphs, and discrete probability.
- Computer science: Digital systems operate on discrete data and use discrete algorithms.
- Physics: The quantization of energy and matter into discrete units is fundamental to quantum mechanics.
- Biology: Genes and DNA sequences are discrete units of genetic information.
