A lookup (table) is an array that replaces run-time computation with a simpler array indexing operation. The savings in terms of processing time can be significant, since retrieving a value from memory is often faster than undergoing an 'expensive' computation or input/output operation. Over time the definition has become less strict, any kind of searching with a key value can be considered a lookup.
