Fundamentals of Operating Systems and Programming

Assignment-1: Role of Operating Systems and Command Line Interface (CLI)

Purpose of the assessment (with ULO Mapping) This assignment assesses the following Unit Learning Outcomes; students should be able to demonstrate their achievements in them.

a. Describe the role of Operating Systems (OS) and its different subsystems in controlling computer hardware
b. Demonstrate competency in the use of a command line interface to operate and perform simple OS administration

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)

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.
II. Short Answer Questions
a. Is Open Source OS really more secure?
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.

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)?

d. Where does the rest of the system reside and how does the rest of the system interact with the kernel?

Section 2: OS Administration using Command Line Interface (CLI)

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
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

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

Assessment - Ethical issues arising from use of ICT technologies

Purpose of the assessment (with ULO Mapping) The purpose of this assignment is to develop skills in research, critical analysis and academic writing of high standard. In this assignment students will:
• Identify potential ethical and social issues related to IT administration ethics.
• Discuss ethical and social issues pertaining to IT systems-administration.
• Interpret professional codes of ethics developed by various industry bodies.
• Discuss ethical behaviour in accordance with professional codes.
• Explain ethical solutions to ensure that the society benefits.

Students must be able to generate ideas at abstract levels and support their arguments with strong reasoning. Students must strengthen critical thinking skills

by answering the assignment.

Assignment Description

Smart technologies are on the rise. There is a body of literature discussing the key benefits of Smart Technologies; however smart technologies also introduce many ethical issues.

0) Social media is becoming addictive for many people. Some people are constantly haunted by the Fear of Missing out (FoMo)? Explore the extent to which the FoMo syndrome is now prevalent in the society and its ethical impacts.

1) Cyberbullying has been a significant issue globally over the past few years. Cyber-technology has exacerbated this problem due to proliferation of mobile applications in the marketplace. You receive notification from a third party through one of the Apps that you use inviting you to participate in an event. You are not sure how they received your details. Discuss what security issues arise due to sharing of too much personal information on social media Apps.

2) Smart phones are being used by nurses for clinical communications and workflow in hospitals. Using smart phones to record patient data introduces ethical issues involving patient privacy. Identify what privacy risks arise in such a context and explain the risks in detail.

3) Technologies such as google glass and smart watches are coming into workplace. Given the intrusive natures of these technologies it is easy for employees to take video or photographs of other people at work and share it with others. What ethical issues arise from use of wearable technologies in workplace?

4) There are many apps available for download for consumers (for example, health monitoring, booking taxi, banking apps). While these Apps are user friendly and improve user experience, there is also a security concern that hackers can use some loopholes in such apps to modify or delete customer information. Discuss an App that you have used recently and if there have been privacy breaches? Is it ethical for companies to introduce Apps with only basic level of security?

Investigate and reflect upon one of the above scenarios using Ethical Guidelines published by organisations such as: EA and ACS.
