WebAug 27, 2009 · Introduction. External sorting refers to the sorting of a file that is on disk (or tape). Internal sorting refers to the sorting of an array of data that is in RAM. The main concern with external sorting is to minimize disk access since reading a disk block takes about a million times longer than accessing an item in RAM (according to Shaffer ... WebMay 12, 2024 · For example, bubble sort, Insertion sort and quick sort can be sorted internally. And external sorting is used when the dataset is large and hence uses algorithms that have minimum space complexity. An example of external sorting is the external merge sort algorithm, which is a K-way merge algorithm.
