Array is a data structure that contains a group of elements. Typically these elements are all of the same data type, such as an integer or string.
In programming, arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value.
The term "array" also refers to:
1. An ordered arrangement of objects or elements
2. A group of devices arranged in a particular pattern
3. In mathematics, a rectangular arrangement of numbers
