Transfer rate of a disk drive can be no faster than the bit density (bits/track) times  the rotational speed of the disk. Figure 7.15 gives a data transfer rate of 112GB/sec.  Assume that the average track length of the disk is 5.5 inches. What is the average bit density of the disk?

Q: Describe the four areas (in order) of a 1.44 MByte diskette

A: Four areas of 1.44MB diskette are: Boot record File allocation table Root directory Data area.

Q: capacity of the drive?

A: Given :- A disk drive has the following characteristics mention in the above given question as,…

Q: If the radius of a CD-ROM is 6 cm, what is the average number of bits per cm2 if the total number of…

A: average number of bits per cm2 = total area/total bits

Q: Compare the bit-map and hole-list methods for keeping track of free space on a disk with 800…

A:

A:

Q: Assume that the average access delay of a magnetic disc is 7.5 ms. Assume that there are 250 sectors…

A: SOLUTION - Given, Average access delay = seek time = 7.5 ms Rotational speed = 7500 rpm 7500…

Q: For a 5,000 RPM disk, assume its average seek time is 7 msec, and it has 100 MB/sec bandwidth;…

A: To answer these questions, we will use the following formulas: Average access time = Average seek…

Q: (2) How is capacity of a 12XCD-ROM given bit rate 150 KB/second, 80 minutes play time?

A: The capacity of CD-ROM = bit rate * Playtime here bit rate = 150 KB/second playtime = 80 minutes =…

Q: A disk drive has 1000 cylinders, 8 tracks per cylinder, 32 sectors per track, and 512 bytes per…

A: Average time = seek time + average rotational latency+ data transfer time.  Here since data transfer…
