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.

b. 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. 

 

Question 1

Question 4 

Explain in your own words any three types of user interfaces in current devices. 

Question 5 

The following is a memory diagram of a computer system at one particular moment. The OS decides to do a memory compaction, what are the values of the base and limit registers after the compaction? Show your result on new diagram. 

Device Management and File Management(6+6+3 marks) 

Question 6 

On a hard disk, the queue of track requests is as follows: 95 180 34 119 11 123 62 64 

Assuming that the head starts at track 50, Draw the diagrams for arm movement for the seek strategies mentioned in the lecture. Calculate the total and average number of tracks travelled. 

Question 7 

Explain RAID(Level 1 to Level 10) with help of figure. 

Question 8 

On your own computer find 6 files that are stored in 6 different directories. For Each File, list both the relative filename and its complete file name. Prepared by: Sadia Aziz Moderated by: Dr Yuba Raj Kafle May, 2020
