It is a storing device.It stores only one bit at a
time.It's output is same as the input.

Answer / radhar

delay flip flop which gives delay of 1bit .which can also
acts as switch

Answer / rajiv

its a Delay-flip flop.it gives a delay of 1 bit.always
works with every single clock pulse.
D flip flops are prefered in most of the designs.

Answer / krishna

It means D Flipflop

Answer / guest

It means Delay Flip-Flop.

Answer / krishna

It means D Flipflop

Answer / minu priya

D flip flop is called as data or delay flip flop.

Answer / madasuvenky

These flip-flops are very useful, as they form the basis for shift registers, which are an essential part of many electronic devices. The advantage of the D flip-flop over the D-type latch is that it "captures" the signal at the moment the clock goes high, and subsequent changes of the data line do not influence Q until the next rising clock edge. An exception is that some flip-flops have a "reset" signal input, which will reset Q (to zero), and may be either asynchronous or synchronous with the clock.

I Agree with youJyotsana Verma

Answer / mathivanan

D-FF means Delay flipflop.1st input is given directly and
2nd input was complement of 1st one and output will be Q and Q'

why we use asynchronous communication in microcontroller.but synchronous is high speed communication than asynchronous.
