Parallel In parallel Out shift registerīack to top Serial in Serial Out Shift Register.A shift register is a sequential circuit which stores the data and shifts it towards the output on every clock cycle.īasically shift registers are of 4 types. The stored information can be transferred within the registers these are called as ‘Shift Registers’. When a number of flip flops are connected in series, this arrangement is called a Register. The series of data bits are stored by registers is called “Byte” or “Word” where a Byte is collection of 8 bits and a Word is collection of 16 bits (or 2 Bytes). The input and outputs of a register are may be serial or parallel based on the requirement. For example, if a computer is to store 16 bit data, then it needs a set of 16 flip flops. Register is a group of flip flops used to store multiple bits of data. In digital electronics, a Register is a device which is used to store the information.įlip flops are use in constructing registers.
As a single flip flop is used for one bit storage, n flip flops are connected in an order to store n bits of data. But if we need to store multiple bits of data, we need multiple flip flops. Parallel in Parallel out shift registerįlip flops can store a single bit of binary data i.e.
