1.	A shift register is defined as ___________(a) The register capable of shifting information to another register(b) The register capable of shifting information either to the right or to the left(c) The register capable of shifting information to the right only(d) The register capable of shifting information to the left onlyI had been asked this question during an interview.Question is from Registers topic in division Registers of Digital Circuits
Answer» RIGHT choice is (b) The register capable of shifting information either to the right or to the left The best explanation: The register capable of shifting information either to the right or to the left is termed as shift register. A register in which data can be SHIFTED only in one DIRECTION is called UNIDIRECTIONAL shift register, while if data can shifted in both directions, it is known as a bidirectional shift register.
