TCP/UDP client-server programs use Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) to transport data between a client and a server. I have used the concept of Socket Programming in C Language. Check the README file to know more info.

# Client and Server Program using both TCP and UDP
A Client and Server Program using TCP ensures reliable, connection-oriented communication. The server listens on a specific port and waits for client requests, establishing a connection to exchange data with guaranteed delivery. Conversely, a UDP based program offers connectionless, faster communication, where the server receives and processes datagrams from clients without establishing a dedicated connection, making it suitable for applications where speed is prioritized over reliability. Both protocols serve distinct needs based on the application's requirements for data integrity and transmission speed.
## Installation
### TCP Client Server Program
* **Step 1**: Complie The Program
```bash
gcc tcpServer.c -o tcpServer # after compiling tcpServer.c, It instructs the compiler to output the compiled executable with the name tcpServer.
gcc tcpClient.c -o tcpClient # after compiling tcpClient.c, It instructs the compiler to output the compiled executable with the name tcpClient.
```
* **Step 2**: Run the Program
```bash
./tcpServer
./tcpClient # run it in another terminal window
```
### UDP Client Server Program
* **Step 1**: Complie The Program
```bash
gcc udpServer.c -o udpServer
gcc udpClient.c -o udpClient
```
* **Step 2**: Run the Program
```bash
./udpServer 5566 # send the port number through argument
./udpClient 5566 # run it in another terminal window
```
## What is Socket Programming?
Socket programming is a way to connect two nodes on a network to communicate with each other. It uses socket APIs to establish communication links between local and remote processes. Sockets are a combination of an IP address and software port number that allows communication between multiple processes.
## What is Socket?
* A socket is effectively a type of file handle.
* A file handle in C is a pointer to a file. It is a data structure that holds information about the file
* You can read and write it (mostly) like any other file handle and have the data go to and come from the other end of the session.
* The specific actions you're describing are for the server end of a socket.
* A server establishes (binds to) a socket which can be used to accept incoming connections.
* Upon acceptance, you get *another* socket for the established session so that the server can go back and listen on the original socket for more incoming connections.
* A socket allows an application to "plug in" to the network and communicate with other applications that are also plugged in to the same network.
* Information written to the socket by an application on one machine can be read by an application on a different machine, and vice versa.

## TCP vs UDP
| Basis | TCP | UDP |
| ------------------------ | ------------------------------------------------- | ------------------------------------------------------ |
| Connection | Connection Oriented | connectionless |
| Usage | High reliability, critical-less transmission time | fast, efficient, small queries, huge number of clients |
| Ordering of data packets | rearranges packets in order | No inherent order |
| Reliability | Yes | No |
| Streaming od Data | Read as a Byte Stream | Sent and read individually |
| Error Checking | Error Checking and Recovery | Simply error checking, no error recovery |
| Acknowledgement | Acknowledgement segments | No acknowledgment |
