Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transfer time in disk performance parameters is time that positioning the head of disk then read and write operation will have performed as the sector moves under the head.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -What is Transfer Time in Disk Scheduling? Transfer time is the time taken to transfer the data from the disk. It varies on the rotational speed of the disk. The faster a disk rotates, the faster we can read data, and the number of bytes on one track can also be called the density of the disk.

Detailed explanation-2: -Seek Time is defined as the time required by the read/write head to move from one track to another.

Detailed explanation-3: -The main measures of the qualities of a disk are capacity, access time, data transfer rate, and reliability, access time: the time from when a read or write request is issued to when data transfer begins.

Detailed explanation-4: -(computer science) Random-access time: the time required to move the hard disk arm to the desired cylinder (seek time) and for the desired sector to rotate under the disk head (rotational latency).
