Suppose that a disk drive has 5,000 cylinders, numbered 0 to 4999. the drive is currently serving a request at cylinder 2150, and the previous request was at cylinder 1805. the queue of pending requests, in fifo order, is:

2069, 1212, 2296, 2800, 544, 1618, 356, 1523, 4965, 3681

starting from the current head position, what is the total distance (in cylinders) that the disk arm moves to satisfy all the pending requests for each of the following disk-scheduling algorithms?

a. fcfs

b. sstf

c. scan

d. look

e. c-scan

f. c-look

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer.  for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate.  for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !

The correct answer is d
