What is a DNS (Domain Name System) server? Differentiate between an authoritative DNS server and a caching DNS server.

 Explain the step-by-step process of configuring a user's machine to obtain an IP address automatically from a DHCP server. Describe the four-step DORA (Discover, Offer, Request, Acknowledge) process.

Differentiate between a "workgroup" and a "domain" model in a Windows networking environment. List two advantages of using a domain model over a workgroup for a medium-sized organization.

Describe the purpose and logical structure of Active Directory in a Windows Server environment. Explain the roles of a Domain, Tree, and Forest in organizing network resources.

Write a shell script in Linux that takes a directory name as a command-line argument. The script should count the number of files and sub-directories within the given directory and display the counts separately. It should also display an error message if the argument is not a valid directory.

Explain the structure of an Inode in a Linux/UNIX file system. What key information does it store about a file? Why is the Inode-based approach efficient for managing file metadata?

What is "thrashing" in the context of virtual memory? Explain why it occurs and describe two methods an operating system can use to prevent or handle thrashing.

A system uses a paging memory management scheme with a page size of 4 KB. The logical address space of a

process is 64 KB. (i) How many pages are in the logical address?

(ii) If the physical memory size is 128 KB, how many frames are in the physical memory?

For the logical address 20500, calculate the page number and the offset.

 Differentiate between pre-emptive and non-pre-emptive scheduling algorithms. Provide one example for each and explain a scenario where one would be more suitable than the other.

Consider a system with three processes (P1, P2, P3) and three resource types (R1, R2, R3). At a particular instance, the system state is as follows:

Total instances of R1-10, R2-5, R3-7.

Using the Banker's Algorithm, determine:

(i) The content of the 'Available' and 'Need' matrices.

(ii) Is the system in a safe state? If yes, provide a safe sequence. Justify your answer.

Explain the concept of a system call in an operating system. Describe the sequence of steps that occur when a user program makes a system call to read data from a file. Use a diagram to illustrate the transition between user mode and kernel mode.

 Compare and contrast a Network Operating System (NOS) with a Distributed Operating System (DOS). Highlight their key differences in terms of resource management, user perception (transparency), and fault tolerance. Provide one example for each type of OS.
