An array is a systematic arrangement of similar objects, usually in rows and columns.
Array may refer to:
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
Science Telescope array, a group of telescopes, mirror segments, or radio telescope antennas used to provide high resolution images of astronomical objects Microarray, a lab-on-a-chip which can measure multiple analytes
Mathematics and statistics Standard array in coding theory Matrices, a rectangular array of numbers in rows and columns Costas array Monge array Holors Orthogonal array Intersection array, a kind of regular graph
Computing Array (data structure), an arrangement of data in computer memory Array (data type), used in a programming language to specify a variable that can be indexed or various kinds of the above, such as: Bit array or bit vector Dynamic array, allocated at run time Jagged array, an array of member arrays which 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 Associative array, an abstract data structure model composed of key-value pairs, often implemented as a hash table or search tree 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 Integrated circuit packages: Ball grid array pin grid array land grid array Processor array Programmable Array Logic (PAL), a systematic way to implement Boolean functions Reconfigurable datapath array, a flexible data processing architecture Systolic array, a hardware architecture Transistor array, an integrated circuit Video Graphics Array (VGA), a display adapter and many variants thereof Wi-Fi array, a wireless networking device
