The Free On-line Dictionary of Computing (30 December 2018):

array

   1.  A collection of identically typed data items
   distinguished by their indices (or "subscripts").  The number
   of dimensions an array can have depends on the language but is
   usually unlimited.

   An array is a kind of aggregate data type.  A single
   ordinary variable (a "scalar") could be considered as a
   zero-dimensional array.  A one-dimensional array is also known
   as a "vector".

   A reference to an array element is written something like
   A[i,j,k] where A is the array name and i, j and k are the
   indices.  The C language is peculiar in that each index is
   written in separate brackets, e.g. A[i][j][k].  This expresses
   the fact that, in C, an N-dimensional array is actually a
   vector, each of whose elements is an N-1 dimensional array.

   Elements of an array are usually stored contiguously.
   Languages differ as to whether the leftmost or rightmost index
   varies most rapidly, i.e. whether each row is stored
   contiguously or each column (for a 2D array).

   Arrays are appropriate for storing data which must be accessed
   in an unpredictable order, in contrast to lists which are
   best when accessed sequentially.  Array indices are
   integers, usually natural numbers, whereas the elements of
   an associative array are identified by strings.

   2.  A processor array, not to be confused with
   an array processor.
