Write a program the implements 3 of the following disk-scheduling algorithms:

a. FCFS

b. SSTF

c. SCAN

Your program will service a disk drive with 5,000 cylinders numbered 0-4,999.

The program will generate a random series of 1,000 requests and service them according to three of the algorithms listed above. The program will be passed the initial position of the disk head as a parameter on the command line and report the total amount of head movement by each algorithm.

See the question already answered below:

Some responsibilities of having a checking account : write checks clearly and carefully.  keep an accurate record of checks written, so you can keep track of payments & deposits made to cover the check. maintain checks register with accuracy so as to avoid returned checks.

That i would call a dead end, since you can't know that it's always possible to immediately reconnect (server could be down, lines between you and the server could be down), and even if it was this would take some time slipping the packages out your wan in the meantime.the solution to this problem rather like satras says to block wan access for those hosts, and if policy routing is being used you need to use the soltion found by fastlanejb in this thread:   the link to the problem forum
