Question

CLV stands for, in terms of rotation of the optical disk ___

(a) Concurrent lines value

(b) Constant Linear velocity

(c) constant linear value

(d) concurrent linear velocity

This question was addressed to me in an online interview.

My enquiry is from Optical Disks in chapter Secondary Storage Devices of Computer Fundamentals

Answer 1

Correct answer is (a) Concurrent lines value

The explanation: It stands for constant linear velocity. The optical disk uses the CLV encoding scheme. Rotation speed depends on the radius of the disk.
