Hypertext Transfer Protocol (HTTP) is a protocol used in networking. When you type any web address in your web browser, your browser acts as a client, and the computer having the requested information acts as a server. When client requests for any information from the server, it uses HTTP protocol to do so. The server responds back to the client after the request completes. The response comes in the form of web page which you see just after typing the web address and press “Enter”.

Hypertext Transfer Protocol Secure (HTTPS) is a combination of two different protocols. It is more secure way to access the web. It is combination of Hypertext Transfer Protocol (HTTPS) and SSL/TLS protocol. It is more secure way to sending request to server from a client, also the communication is purely encrypted which means no one can know what you are looking for. This kind of communication is used for accessing those websites where security is required. Banking websites, payment gateway, emails (Gmail offers HTTPS by default in Chrome browser), and corporate sector websites are some great examples where HTTPS protocols are used.

--URL begins with “http://”
--It uses port 80 for communication
--Operates at Application Layer
--No encryption
--No certificates required

--URL begins with “https://”
--It uses port 443 for communication
--Operates at Transport Layer
--Encryption is present
--Certificates required

The Hypertext Transfer Protocol :It is a network protocol for distributing, hypermedia information system. HTTP is the foundation of data communication for the World Wide Web.
