Consider the following page reference string: 1,2, 3, 2, 5, 6, 3, 4, 6, 3, 7, 3, 1, 5, 3, 6, 3, 4, 2, 4, 3, 4, 5, 1 Indicate page faults and calculate total number of page faults and successful ratio for FIFO, optimal and LRU

The motorway management perceives that the waiting time computed in (a) above is not acceptable and it wishes to reduce it, first, by adding an extra tollbooth assistant to help improve the service rate to 250 motorists every 8-hour-day. The tollbooth attendant will be paid a monthly salary of GH¢400. The second option is that management can add a toll-operated machine which will cost GH¢3,000 and this amount is a free gift from the Minister. This option will reduce the arrival rate to 35 motorists every 2 hours. However, management will have to pay the operator who will man the toll-operated machine a monthly salary of GH¢550. Whichever option management adopts; they avoid lost sales of GH¢1,200.00 per month for every minute that average waiting time is reduced. Advise management which option it must adopt?

Given the page request below, simulate the page replacement FIFO, LRU and optimal algorithm with 4 frames. Determine the hit ratio.7,5,3,1,2,0,3,2,7,1,0,3,2,0,1,7,5,3,6,3,2,0. Provide a handwritten solution for reference on how its done.

You and an electronic engineering student have teamed up to build a robot for detecting coronavirus patients and carriers. You have developed an algorithm for use in building and operating the robot; and you are currently analysing your algorithm. Clearly distinguish between worst-case running time and best-case running time in algorithm analysis; and give relevant practical examples to illustrate your answer. Then again, AIT has established a Help Desk at its KCC Campus; and the Officer-in-charge is using a Help Desk application to store all requests that come through from members of the University community (comprising Students, Lecturers, Deans, President, Technicians, Cleaners, etc.) and then assign them for processing as resources become available. Discuss the data structure that you would recommend for use in such a help desk application at this university; and use appropriate examples to illustrate your answer.

Alice uses Google location services provided by a cloud server, which uses the k-Anonymity technique. She does not want her routine trajectory been detected by others. Bob can easily intercept the communication data sent by Google cloud. Which of the following description is correct? Group of answer choices Bob will easily know Alice's routine trajectory. Bob will not be able to know Alice's routine trajectory. It requires a massive calculation for Bob to know Alice's routine trajectory. Bob will be able to guess Alice's routine trajectory if the k is small.

a. Based on the following data, determine the replacement algorithm use: 2 1 2 4 5 3 4 2 3 1 5 1 4 i. FIFOii. CLOCK b. If using 3 frames, which one is better the following replacements:i. LRUii. Optimal c. There is a fundamental difference between page replacement on Android, Linux and Windows. Name and explain the difference.

Suppose that I have 800 Gigabytes worth of movies on my hard drive at home, and I’d like to get them to a friend in Chicago. I could either send them over the Internet, or I could copy them to a thumb drive, drive to Chicago, and deliver them by hand. Assume that the specs for my cable connection 50 Mbps download / 10 Mbps upload, but the friend in Chicago has a cable connection which gets 25 Mbps download/5 Mbps upload. Which would be faster? Show your work. Note: you are 3 hours from Chicago

In Example 13.4 of section 13.5, we examined whether an M/M/1 system with a single fast server is better or worse than an MMs system with several slow servers. Keeping the same inputs as in the example, use simulation to see whether you obtain the same type of results as with the analytical models. Then repeat, using gamma-distributed service times with standard deviation six minutes. Example 13.4 COMPARING ONE FAST SERVER TO SEVERAL SLOW SERVERS Which system has the better steady-state characteristics such as L, W, LQ, and WQ: a single-server system where the single server can serve 30 customers per hour or a five-server system where each of the servers can serve six customers per hour? For each system, we assume that customers arrive according to a Poisson process at rate 25 per hour. Objective To see whether customers should prefer a system with one fast server or a system with several slower servers. Example 13.5 INCREASINGLY LONG LINES AT COUNTY BANK Over a period of time,…
