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
