### Biology

* Various kinds of multiple biological arrays called microarrays
* Visual feature array, a model for the visual cortex

### Computer science

Generally, a collection of same type data items that can be selected by indices computed at run-time, including:

* Array data structure, an arrangement of items at equally spaced addresses in computer memory
* Array data type, used in a programming language to specify a variable that can be indexed
* Associative array, an abstract data structure model composed of key-value pairs, often implemented as a hash table or search tree

or various kinds of the above, such as:

* Bit array or bit vector
* Dynamic array, allocated at run time
* Jagged array, a multidimensional array where the rows have different lengths individually
* Parallel array of records, with each field stored as a separate array
* Sparse array, with most elements omitted, to store a sparse matrix
* Variable-length array

or various related concepts:

* Array programming, using matrix algebra notation in programs (not the same as array processing)
* Array slicing, the extraction of sub-arrays of an array

or also:

* Global Arrays, a library for parallel processing
* Intel Array Visualizer, a piece of scientific graphics software

### Mathematics and statistics

* A standard array in coding theory
* An array or matrix (mathematics)
* a Costas array
* a Monge array
* A holor
* Intersection array a concept of category theory

## Technology
