Question: 1 / 400

What does a D-Type Flip Flop store?

Two bits

One bit

A D-Type Flip Flop is a type of bistable multivibrator that is used to store a single bit of data. It operates based on the value present at its D (data) input during a clock edge. When the clock signal transitions, the value at the D input is captured and held on the output (Q) until the next clock event. This allows the flip flop to act as a memory storage element, effectively retaining one bit of information—either a '0' or a '1'.

The functionality of a D-Type Flip Flop is essential in digital circuits where temporary data storage is needed, such as in registers, memory systems, and various synchronous circuits. Therefore, the capacity of a D-Type Flip Flop to store one bit is fundamentally interwoven with its design and operational characteristics.
