Definition: Any sort algorithm which uses exclusively main memory during the sort. This assumes high-speed random access to all memory.
See also external sort, quicksort, insertion sort.
Note: Although virtual memory may hide the use of disk, an internal sort is written as if all memory is equally accessible.
