Arrays Online Tutorials

An array is a systematic arrangement of similar objects, usually in rows and columns.

Things called an array include:

Music

In twelve-tone and serial composition, the presentation of simultaneous twelve-tone sets such that the sums of their horizontal segments form a succession of twelve-tone aggregates
Array mbira, a musical instrument
Spiral array model, a music pitch space

A telescope array, also called astronomical interferometer.

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, an array of arrays of which the member arrays can be of different lengths
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:

Array data structure, an arrangement of data in computer memory
Asynchronous array of simple processors
Disk array, such as the RAID
Gate array, including a field-programmable gate array (FPGA)
ICL Distributed Array Processor, an array processor for the ICL
