Implementing Menu-Driven Programs for Data Structures in C
1. Circular Singly Linked List Operations
Develop and implement a menu-driven program in C for the following operations on Circular Singly Linked List (CSLL):
- Insertion at front of SLL
- Deletion at end of SLL
- Display the status of SLL
- Exit
#include
#include
struct Node {
int info;
struct Node* link;
};
typedef struct Node* NODE;
NODE last = NULL;
NODE getnode() {
NODE newNode = (NODE)malloc(sizeof(struct Node));
if (newNode == NULL) {
printf("Memory allocation failed\n");
Database Concurrency, Locking, and Optimization Techniques
Concurrency Control in Databases
Concurrency control addresses issues arising when multiple transactions access a shared database simultaneously. Key problems include:
- Lost Update Problem: Occurs when two transactions update the same record concurrently, leading to one update being overwritten.
- Uncommitted Dependency: Happens when a transaction reads data modified by another uncommitted transaction.
- Inconsistent Analysis: Arises when a transaction reads multiple values, and another transaction modifies
Requirements Engineering: Key Concepts and Practices
Single Statement of Need (SSON) and Non-Functional Requirements (NFR)
SSON (Single Statement of Need) | (Invariant) Forbidden transformations (failure description). NFR: Qualities a system must have: Usability, International, Performance, Environmental, Legal, Security.
Clear, concise, system’s overall goal. Must have: Usability, International, Performance, Environmental, Legal, Security.
How it will accomplish. Stakeholder: Development, Deployment, Maintenance. NFR has two parts:
Source of knowledge.

Bellman-Ford Algorithm in Java
This code implements the Bellman-Ford algorithm, which is used to find the shortest paths from a single source vertex to all other vertices in a weighted directed graph. It can handle graphs with negative edge weights.
import java.util.Scanner;
public class BellmanFord {
private int distances[];
private int numberofvertices;
public static final int MAX_VALUE = 999;
public BellmanFord(int numberofvertices) {
this.numberofvertices = numberofvertices; Read More
Multiplexing, Routers, Modems, and Gateways: A Comparison
Multiplexing Techniques
Multiplexing is a technique used in data communication to combine multiple signals (analog or digital) into a single communication channel. This allows efficient use of bandwidth, reducing the need for multiple transmission lines.
Importance of Multiplexing
- Efficient Bandwidth Utilization: Maximizes the use of the available channel capacity.
- Cost-Effective: Reduces the need for separate channels for each signal.
- Improved Scalability: Enables multiple users or devices to share

LIDT and SLDT Instructions
SLDT (Store Local Descriptor Table) Instruction:
- The SLDT instruction retrieves information about the Local Descriptor Table (LDT) and stores it in a register or memory location.
- Syntax:
SLDT operand - The operand can be a register or a 6-byte memory location where the LDT information will be stored.
- Purpose and Functionality: The SLDT instruction enables the program to obtain details about the LDT, which is a data structure used for managing segment descriptors at the local
