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.

How do u know when a website doesnt like u?
stira [4]
Honest answer a website does not have feelings so therefore there is no way to tell if a website likes you or not!! The reason it may not load is because your IT provider or maybe to firewalls that are set up on your modem. Sometimes its not that and you just need to keep you computer up to date that way it can get on the websites! Hope i helped

Give an example of an outdated memory or storage device what do you think they are outdated
andreev551 [17]

Answer:

HDD technology

Explanation:

You will find that there is a big difference between the SSD and the HDD. The SSD lists out the technical advantages as well as the disadvantages related to HDD, and this has led to the wide use of the SSD rather than the HDD, which is supposed by many being an outdated product. You will find that the SSDs last longer, and they are faster. However, the SSD is more prone to damages as compared to HDD. However, SSD looks like being more advanced considering the above-mentioned advantages, and fewer number of disadvantages. And hence, many people shifted to the SSD from HDD. Remember, SSD stands for solid state drives. And HDD means hard disk drive.

You manage a small LAN for a branch office. The branch office has three file servers and few client workstations. You want to us
lana66690 [7]

You manage small LAN for a branch office. The branch office has three file servers and few client workstations. You want to use Ethernet device and offer guaranteed bandwidth to each server. You design the network by <u>connecting all network devices to a switch. Connect each server to its own switch port.</u>

<u></u>

Explanation:

  • A local-area network (LAN) is a computer network that spans a relatively small area.
  • Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.
  • The LAN is the networking infrastructure that provides access to network communication services and resources for end users and devices spread over a single floor or building.
  • Designing a LAN for the campus use case is not a one-design-fits-all proposition.
  • If there is a single 48-port switch, 47 devices can be supported, with only one port used to connect the switch to the rest of the network, and only one power outlet needed to accommodate the single switch
