Introduction

This lab is all about socket programming, plus point would be to study about HTTPS also to get a better understanding between the socket programming and https

Socket Programming

<aside> 💡 HTTPS : slow yet it need connection from both side … lets see about what is socket programming

</aside>

Socket programming is a way of connecting two nodes (server to server connection) on a network to communicate each other using sockets.

• one socket node will listens on a particular port at an IP
• other sockets reaches out to the form a connection
• There are server and client in the socket programming, server send the message and client receive the message

Sockets are an interface that programs use to send and receive message across a network.

There are two types of Sockets : TCP and UDP

TCP vs UDP

• TCP don't transfer until all the packets are not connected, data is slow but secure, chances of data, loss is less i.e. message
• UDP will directly share the packet , it don't create package, its fast data transfer i.e. live video streaming.

Code in python

socket() —> default will follow the IPv4 (there are difference in protocols)

bind() —> with which client you will bind first parameter (Ip address , port number)

listen() —> how many clients we will listen i.e. listen 5 means conversation with 5 clients

accept() —> message accept request or reject
