Difference between Recursion and Iteration

RECURSION	ITERATIONS
Recursive function – is a function that is partially defined by itself	Iterative Instructions –are loop based repetitions of a process
Recursion Uses selection structure	Iteration uses repetition structure
Infinite recursion occurs if the recursion step does not reduce the problem in a manner that converges on some condition.(base case)	An infinite loop occurs with iteration if the loop-condition test never becomes false
Recursion terminates when a base case is recognized	Iteration terminates when the loop-condition fails
Recursion is usually slower then iteration due to overhead of maintaining stack	Iteration does not use stack so it's faster than recursion
Recursion uses more memory than iteration	Iteration consume less memory
Infinite recursion can crash the system	infinite looping uses CPU cycles repeatedly
Recursion makes code smaller	Iteration makes code longer
