Purpose of the
assessment
(with ULO
Mapping)
The purpose of this assignment is to report on some important characteristics of
Operating Systems. Students must answer Multiple Answer questions and
provide written answer about process, file and device management, deadlock,
and UNIX commands. After successful completion of this assignment, students
should be able to:
a. Report on the basics, and provide examples, of operating systems structure
and functionality, including memory allocation, virtual memory, demand
paging and process and device management.
. Describe the integration of hardware, operating systems and application
software.
c. Explain in detail the functioning of some devices such as peripherals (e.g.
printers and network connections).
d. Discuss the most common file systems structure and technology.
e. Explain the concept of user interfaces and their role in the functionality of an
OS.
f. Demonstrate competency in the use of a command line interface to
operate with and manage an OS such as UNIX, and perform simple UNIX
(Linux) administration.
g. Support and troubleshoot operating systems and applications at an
introductory level.

Introduction to operating System(5+5 marks)
Question 1
Explain with an example (any application that is not mentioned in slides) all the steps which are taken
y all the managers of operating system cooperating with each other from initiation till the complete
execution of the application. For example if you are clicking on video file how different resources are
allocated to play the video
