MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Shift Register. A group of flip flops which is used to store multiple bits of data and the data is moved from one flip flop to another is known as Shift Register. The bits stored in registers shifted when the clock pulse is applied within and inside or outside the registers.

Detailed explanation-2: -A shift register is a type of digital circuit using a cascade of flip-flops where the output of one flip-flop is connected to the input of the next. They share a single clock signal, which causes the data stored in the system to shift from one location to the next.

Detailed explanation-3: -A simple Shift Register can be made using only D-type flip-Flops, one flip-Flop for each data bit. The output from each flip-Flop is connected to the D input of the flip-flop at its right. Shift registers hold the data in their memory which is moved or “shifted” to their required positions on each clock pulse.

Detailed explanation-4: -Shift Registers are used for data storage or for the movement of data and are therefore commonly used inside calculators or computers to store data such as two binary numbers before they are added together, or to convert the data from either a serial to parallel or parallel to serial format.

Detailed explanation-5: -A register is a group of flip-flops used to store a binary word. One flip-flop is needed for each bit in the data word.
