Answer Posted / udhaya
the internal sorting can reside in main memory....external
use secondary memory.....
-internal sorting is independent of time to read/write a
record...external ids dependent on the same
-internal sorting takes input only which can be fit into
its memory...i.e. it takes small input....whereas external
sorting can take as much as large input...
