Difference between internal and external sorting?

Answer 1

Internal sorting

it means we are arranging the number within the array only which is in computer primary memory.

External sorting

it is the sorting of numbers from the external file by reading it from secondary memory.

Answer 2

Internal Sorting takes place in the main memory of a computer. The internal sorting methods are applied to small collection of data. It means that, the entire collection of data to be sorted in small enough that the sorting can take place within main memory.

The External sorting methods are applied only when the number of data elements to be sorted is too large. These methods involve as much external processing as processing in the CPU. This sorting requires auxiliary storage.

-internal sorting takes small input, whereas external sorting can take as much as large input...

-The external sorting algorithm has to deal with loading and unloading chunks of data in optimal manner.

Answer 3

External sorting: - Merge sort - Two way merge sort. Internal sorting: - Heap sort - Bubble sort - Tree sort - quick sort - shell sort - Insertion sort External sorting: - Merge sort - Two way merge sort. Internal sorting: - Heap sort - Bubble sort - Tree sort - quick sort - shell sort - Insertion sort

Answer 4

Internal sorting is done in internal memory. where as
external sorting is done in external memory like hard disk or magnetic tape.

Answer 5

Internal sorting does not make use of extra resources.
