Define HTTPS. How is it different from HTTP?

HTTPS or Hypertext Transfer Protocol Secure is the secure version of HTTP which is the only primary protocol browsers use to connect to web servers and display web pages to us. HTTPS uses asymmetric encryption to secure the data in transit between webserver and the client.

HTTPS is particularly favourable where privacy is more relevant. These can be situations where we are making online transactions, logging into our bank or other tasks which would include the usage of sensitive document.
