Computer Architecture And Design Interview Question:

What are Flip-flops?

Submitted by: Administrator

★ Flip flops are also known as bi-stable multi-vibrators. They are able to store one bit of data.
★ Flip flops are able to be in two stable states namely one and zero. They can be in either states and in order to change their states they have to be driven by a trigger.
★ Certain flip flops are edge triggered meaning they only respond to voltage changes from one level to another. They can be either positive edged triggering or negative edged triggering.
★ Flip flops turn on in a random manner that is they can be in either of the states when they are turned on. In order to have a uniform state when they are powered on a CLEAR signal has to be sent to the flip flops. They can also be made to turn on in a particular state by applying PRESET.
