Given that it takes 0.08 ms to travel from one track to the next of a hard drive; that the arm is originally positioned at Track

15 moving toward the low-numbered tracks; and that you are using the LOOK scheduling policy: Compute the total seek time to satisfy the following requests-4, 40, 35, 11, 14, and 7. Assume all requests are initially present in the wait queue. (Ignore rotational time and transfer time; just consider seek time.)

Answer:

Time taken to travel from one track to the next = 0.08ms

Initial track= 15     0

4      (15-4)*(0.08)= 0.88

40     (40-4)*(0.08)= 2.88

35      (40-35)*(0.08)= 0.4

11       (35-11)*(0.08)= 1.92

14       (14-11)*(0.08)= 0.24

7         (14-7)*(0.08)= 0.56

----------------------------------------------

Total seek time=0.88+2.88+0.4+1.92+0.24+0.56=6.88ms

Explanation:

We caculate the seek time for each request, and then add them together to find the total seek time. The final track number for the current request becomes the current track of next request, and this process is repeated till the last request is processed.

If you want a user to enter exactly 20 values, which loop would be the best to use?
Hitman42 [59]

Answer: For loop

Explanation:

Using the for loop we can get the exact number of values/outcomes we require.

For example:    printf(enter 20 numbers");

                               for(int i=0; i<20;i++)

                               {

                                       scanf("%d", &number);

                                }

So, this is an implementation of for loop in C. Using it we can enter exact 20 numbers not less or more than that.

Therefore, for loop is the answer.

What subnet mask can be used to segment the 172.16.0.0 network to allow for a minimum of 6 subnets while maximizing the number o
marishachu [46]

The subnet mask can be utilized to segment the 172.16.0.0 network to qualify for a minimum of 6 subnets while maximizing the numeral of broadcasters per subnet is 255.255.224.0

<h3>What do subnet masks mean?</h3>
  • A subnet mask is a 32-bit numeral formed by setting keeper bits to all 0s and developing network times to all 1s.
  • In this way, the subnet mask divides the IP speech into the network and host addresses.
  • A subnet mask is used to separate an IP address into two pieces. One element defines the host (computer), and the different part identifies the network to which it belongs.
  • To better comprehend how IP lessons and subnet masks work, look at an IP speech and see how it's managed.
