What is diference between http and https?

HTTP(Hpertext Transfer Protocol) is a protocol used in application layer for transmitting and retrieving information across internet.Http request could be sent and you get a response for that..

HTTPS(hypertext Transfer Protocol Secure) works by transmitting normal http interactions through an encrypted system and the information cannot be accessed by any party other than the client and end server. Two types of encryption layer available are Transport Layer Security (TLS) and Secure Sockets Layer (SSL), both of which encode the data records being exchanged.
