What is the difference between an S-R and J-K flip flop?

(Please do not post a long paragraph. I only need a few sentences.)

Solution

Jk flip flop is improved version of St flip flop.

In sr flip flop both should be high when clock is triggered.and in this condition output can\'t be determined

Whereas in jk flip flop if both are high output is toogled(high and low).
