WHAT IS REGISTER ?
A register is basically a an array or a group of flip-flops used for storing binary information. As we know that the flip-flop is the basic block of storage, one flip-flop can store one bit of information. For storing n-bit in register, it will require ‘n’ number of flip-flops. Registers are mainly used for storing and shifting information.
Registers finds its application in many other digital devices like serial adder , microprocessors , multipliers , dividers etc.
SHIFT REGISTER – These register capable of shifting binary information either to the right or to the left is called shift register. The binary information within the register is shifted after each succeeding clock pulse.
CLASSIFICATION OF SHIFT REGISTER
Shift registers are classified into the following types based on the how the data is stored or shifted.
