Array - GCSE Computer Science Definition

An array is a fundamental data structure used in computer science and programming, especially pertinent for students studying GCSE Computer Science. It consists of a collection of elements, each identified by an index or key, which are stored in a continuous block of memory. Typically, arrays hold elements of the same data type, such as integers or strings, allowing for efficient access and manipulation of data. They are widely used for organising data, performing repeated operations like iteration, and implementing complex data structures like matrices and lists. Understanding arrays is crucial as they form the basis for learning more advanced programming concepts and algorithms.
