shift register

[′shift ‚rej·ə·stər]
(computer science)
A computer hardware element constructed to perform shifting of its contained data.

shift register

A high-speed circuit that holds some number of bits for the purpose of shifting them left or right. It is used internally within the processor for multiplication and division, serial/parallel conversion and various timing considerations. See register.
