Networked-Systems-Programming

This repository provides example implementations of client-server applications in both C and Java. The C code demonstrates a low-level approach using standard POSIX socket programming libraries, while the Java application is built with Spring Boot and integrates with MongoDB along with several additional features.

Note: Each folder contains its respective track file detailing the exercise instructions and progress.

Overview

This project is divided into two main parts:

1. C Implementation:
   The C programs implement a basic client-server model using low-level socket programming. The following libraries are used:

   • <sys/socket.h>
   • <netinet/in.h>
   • <arpa/inet.h>
   • <stdio.h>
   • <string.h>
   • <unistd.h>

2. Java Implementation (Spring Boot):
   The Java application leverages the Spring Boot framework to create a robust server. It integrates with MongoDB for data persistence and includes features such as RESTful API endpoints and security configurations.
