Shift Register

A shift register is a digital circuit that stores and moves binary data bits in a sequential, cascaded manner. It consists of a chain of flip-flops where data is shifted from one stage to the next with each clock pulse, allowing bits to be moved left or right through the register. Shift registers are commonly used for serial-to-parallel data conversion, parallel-to-serial conversion, temporary data storage, and creating time delays in digital systems. They are essential components in applications like LED matrix displays, communication interfaces, and digital signal processing.
