Submission Format You should take the screenshot of your computer display while solving the exercises and paste the image in the doc\docx file. You should also write briefly at the end of each screenshot explaining its purpose and finally summarize your understanding of the whole task (what you have done and how) that you completed. Your name, ID and course code and name should be there in the coversheet of your document. Submit the document in PDF format, in case you can’t find anyway to convert it to PDF, then submit in doc\docx format. Remember submitting in PDF, keeps the formatting\fonts etc. of your document in place and the overall presentation remains nice and intact. Online research are allowed for all the tasks. Lab Assessment 03 PART-01: Process Scheduling Draw the Gantt chart and find the average waiting time of the following processes using Priority scheduling (Highest Priority Integer denotes the highest priority): Process Burst Time Priority P1 6 3 P2 3 2 P3 1 4 P4 3 1 PART-02: BASH Scripting Task 1: Write a program using ‘While Loop’ that will accept 6 integers from user within the range of 6 to 60 and will calculate Sum of all the inputted numbers. If the user enters any other value that doesn’t fall into the range of 6-60, an appropriate error message should be shown and the program should ask for an input again. Attach the clear screenshots showing the complete code for each of the programs. PART-02: Windows Task 1: Open up Windows 10 Performance Monitoring toolkit and complete the following sub-tasks with clear screenshots and summary. First clear all existing counters. a) Add any 3 counters (1 from each category) from ‘FileSystem Disk Activity’, ‘GPU Process Memory’ and ‘IPv4’. b) Change the colour and line width of any of the added counter, as well as add a Title. c) The default graph style is Line graph, alter it to Histogram. d) Save the image of the graph as .gif file and the settings as HTML file.

The following list shows the policies. Configure these in any of the VMs. Note: execute the command ‘secpol’ from run dialog box to open up the relevant dialog box, all of the below policies can be configured there. Passwords has to be at least 9 characters. A user may change their password once a day. Passwords must be changed every 105 days. User will have to provide a unique password for a minimum of 5 changes of the password. Users will be locked out of the computer after 4 failed attempts and must delay any further attempt for at least 15 minutes for the lookout counter to reset. User will automatically be logged out after 20 minutes of inaction Users will be reminded to alter the current password 7 days prior its expiry.

Lab Assessment 03
PART-01: Process Scheduling
Draw the Gantt chart and find the average waiting time of the following
processes using Priority scheduling (Highest Priority Integer denotes
the highest priority):
Process Burst Time Priority
P1 6 3
P2 3 2
P3 1 4
P4 3 1
PART-02: BASH Scripting
Task 1:
Write a program using ‘While Loop’ that will accept 6 integers from user
within the range of 6 to 60 and will calculate Sum of all the inputted
numbers.
If the user enters any other value that doesn’t fall into the range of 6-60,
an appropriate error message should be shown and the program should
ask for an input again.
Attach the clear screenshots showing the complete code for each of the
programs.
PART-02: Windows
Task 1:
Open up Windows 10 Performance Monitoring toolkit and complete the
following sub-tasks with clear screenshots and summary.
First clear all existing counters.
- a) Add any 3 counters (1 from each category) from ‘FileSystem Disk
Activity’, ‘GPU Process Memory’ and ‘IPv4’.
- b) Change the colour and line width of any of the added counter, as
well as add a Title.
- c) The default graph style is Line graph, alter it to Histogram.
- d) Save the image of the graph as .gif file and the settings as HTML
file. Both cases use your StudentID as the file name.
Task 2:

(Enterprise edition) computers at one of divisions in your company; the
computers each need to be configured according to the security policy
for the organization. The following list shows the policies. Configure
these in any of the VMs.
Note: execute the command ‘secpol’ from run dialog box to open up the
relevant dialog box, all of the below policies can be configured there.
