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 functionalities on different devices. 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 in various computing and communication devices. Also, they will appreciate the ease of using GUI over CLI.

Assignment 1 Specifications


Section 1:  Operating Systems                                   (3marks X 5 features X 3 OSs = 45marks)

The Operating system acts as an interface between the user and the computer hardware. Discuss in detail the roles of the OS as a resource manager and as an extended machine on the following systems:

  • Client,
  • Server, and
  • Mobile devices.

Students may consider any of the OS for discussions, for instance, Windows, Linux, iOS, MacOS, Android, etc. Further, the students must consider any five of the following features relevant to the systems for discussions.

How does OS on a client/server/ mobile system

  • support many devices simultaneously
    • allocate resource to different users
    • share resources among users fairly, efficiently, and safely
    • resolve conflict in resource demand
    • hides the implementation details
    • Provide a stable, portable, reliable, safe, well-behaved environment
    • manage memory, processor, file etc.
  • the level of security it provides

For instance, the students may opt the following to answer section 1.

operating systems

System Type OS for the system selected Features
Client Windows  Explain any 5 features and 3 marks each  3*5 = 15
Server Linux  Explain any 5 features and 3 marks each  3*5 = 15
Mobile OS Android  Explain any 5 features and 3 marks each  3*5 = 15
45 marks

Section 2:  OS Administration using Command Line Interface (CLI)                                 (20 marks)
