| Submission Guidelines | · Submit a word document that contains the screen shots of the answers to all the questions in section 2 (Unix exercises) along with the answers for questions in section 1. All screen shots submitted on Moodle must carry your unique id such as MITID, names etc. · All work must be submitted on Moodle by the due date along with a completed Assignment Cover Page. · The assignment must be in MS Word format, 1.5 spacing, 11-pt Calibri (Body) font and 2 cm margins on all four sides of your page with appropriate section headings. · Reference sources must be cited in the text of the report, and listed appropriately at the end in a reference list using IEEE Transactions on Networking referencing style. · Students must ensure before submission of final version of the assignment that the similarity percentage as computed by Turnitin has to be less than 10%. Assignments with more than 10% similarity may not be considered for marking. |
| Extension | If an extension of time to submit work is required, a Special Consideration Application must be submitted directly through AMS. You must submit this application within three working days of the assessment due date.

| Academic Misconduct
| Academic Misconduct is a serious offence. Depending on the seriousness of the case, penalties can vary from a written warning or zero marks to exclusion from the course or rescinding the degree. Students should make themselves familiar with the full policy and procedure available at: http://www.mit.edu.au/about-mit/institute-publications/policies-procedures-and-guidelines/Plagiarism-Academic-Misconduct-Policy-Procedure. For further information, please refer to the Academic Integrity Section in your Unit Description. |
Purpose of the Assignment:
The assignment focuses on two aspects, the role of OS as an interface between the user and the computer hardware, and the use of command line interface. It helps the students to understand the different types of OS and their relative performances. Also it assists the students to gain competency in using UNIX/LINUX commands in performing simple OS administration.
By doing this assignment, students will get to learn to research and comprehend the basic concepts of OS and how differently or similarly they play the interfacing role on various computing and communication devices. Also, they will appreciate the ease of using GUI over CLI.
Assignment 1 Specifications
_________________________________________________________________________________
Section 1: Operating Systems(OS) (30marks)
I. The Operating system acts as an interface between the user and the computer hardware. Compare and contrast the Unix OS with Window OS in terms of the following:
Stability
Performance
Compatibility
Reliability
Justify your statements with suitable examples and references. 12 marks.
II. Short Answer Questions
a. Is Open Source OS really more secure? Justify your answer 5 marks
b. In a multiprogramming and time-sharing environment, several users share the system simultaneously. This situation can result in various security problems.
a. What are two such problems?
b. Can we ensure the same degree of security in a time-shared machine as we have in a dedicated machine? Explain your answer. 7 marks
c. What is the purpose of having a kernel and What is the least functionality a kernel has to provide usually (Hint: Usually a minimal kernel provides three properties)? 4 marks
d. Where does the rest of the system reside and how does the rest of the system interact with the kernel? 2 marks
Section 2: OS Administration using Command Line Interface (CLI) (20 marks)
_________________________________________________________________________________
Refer to the man command to understand the syntax and parameters for the commands that you would be using in this section.
This section is divided into 2 sections: Security related commands and Unix networking commands. You all have to demonstrate the following Unix/Linux commands in the lab to your tutor before week 6 and paste the screen shots of the execution in the same word file that has section 1 of the assignment.
I. Security related commands 8 marks
On a Unix/Linux system, each file and directory is assigned access rights for the owner of the file, the members of a group of related users, and everybody else. Access rights can be assigned to read a file, to write a file, and to execute a file (i.e., run the file as a program).
1) Create a file in your home directory, name it with your MITID?
2) What are the default file permissions assigned to the newly created file?
3) Change the default permissions to group, read & write access and verify the same
4) Create a directory with your name and store the file with your id in it.
5) Check the default setting of the directory created and change them to all with RWX permissions and verify the same.
6) Reset the user password
II. Unix networking Commands 12 marks
Run through the following commands and discuss the outputs you get. Also, paste the screen shots of the output obtained in the same word file used for above question and section 1 of the assignment.
1) Ping
2) Ifconfig
3) netstat
4) nslookup (Hint: You have an IP address in your network how will you find hostname and vice versa?)
5) hostname
6) ARP
