difference between http:// and https://

both http and https protocols help exchange data or information of a particular website in between Web Server and Web Browser. the difference between http and https is that https is much more secure compared to http.

Hyper Text Transfer Protocol (HTTP) using which  data/hypertext between web server and web browser is exchanged .the data exchanged using http is not that much secure, as the hyper-text exchanged using http goes in the form of plain text . 
In HTTP, URL begins with “http://”.it uses port number 80 for communication.it Works at Application Layer. In HTTP, Encryption is absent as it sends data in the form of plain text. and it does even require any certificates .

Hyper Text Transfer Protocol Secure(HTTPs) exchanges data/hypertext between web server and web browser in a secured way. In HTTPs, URL begins with “https://”. it uses port number 443 for communication. it Works at transport Layer. In HTTPs, Encryption is present to transfer secured data. and it requires SSL certificates .

cryptographic protocols such as SSL and/or TLS convert http into https.
