NSSet and NSMutableSet both classes stores unordered collection of distinct objects. but In NSSet when we establish a static set's entries and when it's created, thereafter we can't modified the NSSet entries. On the other hand NSMutableSet allows addition and deletion of entries at any time and also automatically allocating memory as needed.
