Circuit used as ‘Memory Device’ in Computers
Which of the following circuit is used as ‘Memory Device’ in computers?
A. Rectifier
B. Flip-Flop
C. Comparator
D. Attenuator
Answer: Flip-Flop
A flip-flop or latch is a circuit that has two stable states and can be used to store state information. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic. Flip-flops and latches are the fundamental building block of digital electronics systems used in computers, communications, and many other types of systems.
Flip-flops and latches are used as data storage elements. A flip-flop is a device which stores a single bit (binary digit) of data; one of its two states represents a “one” and the other represents a “zero”.
