4-bit shift register
Explanation:
A serial to parallel converter is a digital circuit where the input data is fed serially, and the output happens in parallel fashion. A 4-bit serial-to-parallel shift register is one of the simplest types of circuits comprising of four D-type flip-flops. It is widely used in modern digital electronics. Data communications from a USB port or a SATA hard disk drive are in serial. Usually, there is a controller IC that converts this data into parallel before sending it to the microprocessor.
