1. What are the types of Operating System? Discuss the application areas of Real-time software.
Ans: Types of Operating System:-
Personal Computer Operating Systems
The main mode of use of a PC (as its name implies) is by a single user. Thus Os for PCs were designed as a single user single task operating system, that is, it is assumed that only one user uses the machine and runs only one program at a time. The operating system of PCs consists of two parts. One part is Its Half solved only

2. What is Preemptive and Non-preemptive Scheduling? Discuss any three CPU scheduling algorithms.
Ans: Scheduling can either be pre-emptive or non-pre-emptive. If pre-emptive, then an executing process can be stopped and returned to ready state to make the CPU available for another ready process.
But if non-preemptive
3. Discuss the use of semaphores. What are monitors?
Ans: Semaphores are the classic method for restricting access to shared resources (e.g. storage) in a multi-processing environment. They were invented by Dijkstra and first used in T.H.E operating system.
A semaphore is a protected variable (or abstract data type) which can only be accessed using the following

4. a. What is a Process Control Block? Explain its use.
Ans: Every process has a number and a process control block (PCB) represents a process in an operating system. The PCB serves as a repository of information about a process and varies from process to process. The PCB contains information that makes the process an active entity. A PCB
b. What is Thrashing? What are its causes?
Ans: Thrashing: When a process does not have enough frames or when a process is executing with a minimum set of frames allocated to it which are in active use, there is always a possibility that the process will page fault quickly. The page in active use becomes a victim and hence
5. a. Discuss the different File Access Methods.
Ans: Information is stored in files. Files reside on secondary storage. When this information is to be used, it has to be accessed and brought into primary main memory. Information in files could be accessed in many ways. It is usually dependent on an application. Access methods
b. What are I/O Control Strategies?
Ans: Several I/O strategies are used between the computer system and I/O devices, depending on the relative speeds of the computer system and the I/O devices. The simplest strategy is to use the processor itself as the I/O controller, and to require that the device follow a strict order of events under direct program control, with the processor waiting for the I/O device at
6. Explain the different Multiprocessor Interconnections and types of Multiprocessor Operating Systems.
Ans: The nature of multiprocessor interconnections has an effect on the bandwidth for communication. Complexity, cost, IPC and scalability are some features considered in interconnections. Basic

Assignment Set – 1
1. a. Explain the advantages of linked list over arrays.
Ans: Let us see how stack is implemented using linked list. As we have seen in previous section the advantages of linked list over array is that, it is not necessary to declare the size of linked list a-head and the size can be changed dynamically. So, at any point we can expand or shrink the stack size.

2. Define and explain the structure of AVL tree.
Ans: AVL tree: An AVL tree is another balanced binary search tree named after their inventors, Adelson-Velskii and Landis. An empty binary tree is an AVL tree. A non empty binary tree T is an AVL tree if given TL and TR to be the left and right subtrees of T and h(TL) and h(TR) to be the heights of subtrees TL and TR respectively. TL and TR are AVL trees and h(TL)-h(TR) ≤ 1. h(TL) – h(TR) is known as the balance factor. AVL tree is referred in the figure.
3. a. Define and explain the concept of binary search tree and discuss the algorithm for insertion in BST.
Ans: Concept of Binary Search Tree T is a binary tree. Then T is called binary search tree if each node of n of T has the following property. The value at n is greater than every value in the left sub tree of n and is less than every value in the right sub tree of n. We can say one of the most important data structure is binary search tree. This enables one to search for and find an element with an average running

4. a. What is static memory allocation and dynamic memory allocation?
Ans: Static memory allocation: It is a memory allocation strategy in which the operating system allocates a predetermined amount of memory during build time and manages it using a data structure called stack.
For example, th
b. Give algorithm/pseudocode for DFS. Demonstrate DFS using suitable example?
Ans: Depth First Search (DFS) In this tutorial, you will learn about depth first search algorithm with examples and pseudocode. Also, you will learn to implement DFS in C, Java, Python, and C++. Depth first Search or Depth first traversal is a recursive algorithm for se
5. a. Write an algorithm to implement Bubble sort with suitable example.
Ans: Bubble sort Bubble sort:- Itis a straightforward and simplistic method of sorting data that is used very commonly. The algorithm starts at the beginning of the data set. It compares the first two elements, and if the first is greater than the second, then it swaps them. It continues doing this for
6. Explain how Dijkstra’s algorithm is used to find the shortest path of Directed weighted graph.
Ans: Weighted Shortest Paths – Dijkstra’s Algorithm This algorithm is used to find the shortest path between the two vertices in a weighted directed graph and it is also very popular and efficient to find each and every path from starting (source) to terminal vertices. Let w(vi , vj ) be the weight associated

b. What are the major goals of SONET design?
Ans: SONET were designed to transmit circuit mode communications (e.g., DS1, DS3) from a variety of different sources, but they were principally meant to enable real-time, uncompressed, circuit-switched audio encoded in PCM format. Prior to SONET/SDH, the main challenge was that the synchronization sources of these multiple circuits were all different. This

6. Discuss symmetric key and asymmetric key cryptography in detail.
Ans: Symmetric Key Cryptography
Symmetric Key Cryptography, or Symmetric Encryption, uses a secret key for both encryption and decryption. This approach is the inverse of Asymmetric Encryption, which uses one key to encrypt and another to decrypt. Data is translated to a format that cannot be interpreted or inspected by someone who does not have the secret key used to encrypt it during this phase.
