Consider the following set of processes, with the length of the cpu burst given in milliseconds:

process burst time priority
p1 2 2
p2 1 1
p3 8 4
p4 4 2
p5 5 3
the processes are assumed to have arrived in the order p1, p2, p3, p4, p5, all at time 0.

a. draw four gantt charts that illustrate the execution of these processes using the following scheduling algorithms: fcfs, sjf, nonpreemptive priority (a larger priority number implies a higher priority), and rr (quantum - 2)

b. what is the turnaround time of each process for each of the scheduling algorithms in part a?

c. what is the waiting time of each process for each of these scheduling algorithms?

d. which of the algorithms results in the minimum average waiting time (over all processes)?

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl
