Q1:

A flip-flop has ________.

A one stable state

B no stable states

C two stable states

D none of the above

ANS:C - two stable states

The output of a flip-flop can be changed by bringing a small change in the input signal. This small change can be brought with the help of a clock pulse or commonly known as a trigger pulse. When such a trigger pulse is applied to the input, the output changes and thus the flip-flop is said to be triggered.
