Unit I
Overview
General Overview of the System: History – System Structure – User Perspective -Operating System Services – Assumptions about Hardware – Introduction to the Kernel Architecture of the UNIX Operating System – Introduction to System Concept – The Buffer Cache – Buffer headers – Structure of the Buffer Pool – Scenarios for Retrieval of a BufferReading and Writing Disk Blocks – Advantages and Disadvantages of the Buffer Cache.
Suggested Activities:
- Flipped classroom on operating system services.
- Practical –
- Implement the system call “cat” using command line arguments and generate the executable version of the program and invoke the executable file using exec system calls (fork, wait etc).
- Implement a scenario resulting to an incorrect linked list because of context switch.
- Implement the five scenarios in the getblk algorithm by using first in first out scheme.
- Simulate the function of bread(), breada(), bwrite and brelse.
Suggested Evaluation Methods:
- Quiz on operating system services.
Evaluation of the functions implemented.

Unit III
System Calls for the File System
Open – Read – Write – File and Record Locking – Adjusting the Position of File I/O – lseek -Close – File Creation – Creation of Special Files – Changing Directory – Root – Owner -Mode – stat and fstat – Pipes – dup – Mounting And Unmounting File Systems – link -unlink.
Suggested Activities:
- Flipped classroom on file system and system calls.
- Practical –
- How does the command mkdir work? (Hint: When mkdir completes, what are the inode numbers for “.” and “..”?).
- Simulate the function of chown, chmod, stat and fstat.
- Set the whole-file lock with fcntl() and lockf().
- Write a program to print the mount table whenever an external device is connected to the Unix system.
Suggested Evaluation Methods:
- Quiz on file system calls.
- Checking the functions implemented.

Unit V
Memory Management and I/O
Memory Management Policies – Swapping – Demand Paging – The I/O Subsystem: Driver Interface – Disk Drivers – Terminal Drivers.
Suggested Activities:
- Flipped classroom on virtual memory concepts
- Practical –
- Write a program that tracks the allocation of space on a swap device.
- Write a program that verifies that the file systems on a disk do not overlap. The program should take two arguments: a device file that represents a disk volume and a descriptor file that gives section numbers and section lengths for the disk type. The program should read the super blocks to make sure that file systems do not overlap.
- Implement sty command: with no parameters, it retrieves the values of terminal settings and report them to the user.
- Encode a line disciple that writes the machine name at the beginning of each line of output.
Suggested Evaluation Methods:
- Quiz on virtual memory concepts.
- Evaluation of the functions implemented.
