REGISTERS egisters are used to store Group of Bits. To store N bits , N flip flips are cascaded in Register.

Group of Flip Flops connected together to store 4 bit data CLK CLK CLK CLK clock
4 BIT Shift Register IN 0 OUT
Types of Registers 1. Based on shift:- Left Shift , Right Shift 2. Based On l/O :- SISO,SIPO,PIPO,PIPCO
SiSO Serial in Serial Out Types OFSIP Registers (based on PISO Serial in Parallel Out l/O) Parallel in Serial Out PIPO Parallel in Parallel OUT
In Serial Form, Bits are arranged , ONE at a Time. In Parallel Form, all Bits are available at the SAME Time. The Serial Form is called Temporal Code. The Parallel Form is called Special Code. Data can be changed from Temporal code to Special Code by using Shift Registers also vice versa. Universal Register accepts both serial and parallel input and gives serial and parallel Output.
