Difference between HTTP and https

 What is HTTP??

Hypertext Transfer Protocol (HTTP) is a protocol used in networking. When we type any web address in our web browser, our 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.

HISTORY OF HTTP:                                                                                                                                           The term hypertext was coined by Ted Nelson in 1965 in the Xanadu Project, which was in turn inspired by Vannevar Bush's vision (1930s) of the microfilm-based information retrieval and management "memex" system described in his essay As We May Think (1945).Tim Berners-Lee and his team at CERN are credited with inventing the original HTTP along with HTML and the associated technology for a web server and a text-based web browser. Berners-Lee first proposed the "WorldWideWeb" project in 1989 — now known as the World Wide Web. The first version of the protocol had only one method, namely GET, which would request a page from a server. The response from the server was always an HTML page.



 What is HTTPs??   
  
  

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  and corporate sector websites are some great examples where HTTPS protocols are used.  

HISTORY OF HTTPs:
      Netscape Communications created HTTPS in 1994 for its Netscape Navigator web browser.Originally, HTTPS was used with the SSL protocol. 
 Here are some major difference between HTTP and HTTPs:

So from the above we find that both URLs are used by us but the more secured and reliable is httpsJ
