What is internal sorting with example?

Internal sorting refers to the process of sorting data that is entirely loaded into a computer's main memory (RAM). An example of internal sorting is using algorithms like QuickSort or MergeSort to arrange an array of integers stored in memory. Since all the data fits in RAM, these algorithms can operate efficiently without needing to access slower external storage. This is in contrast to external sorting, which involves sorting data that does not fit into memory and requires the use of disk-based storage.
