    What i know is http is hyper text transfer protocol which is responsible for transmitting and receiving information across the Internet where as https is secure http, which is used exchanging confidential information with a server, which needs to be secured in order to prevent unauthorized access.

    So when you are attempting to do some secure transaction over internet use https.

    HTTP is Hyper Text Transport Protocol and is transmitted over the wire via PORT 80(TCP). You normally use HTTP when you are browsing the web, its not secure, so someone can eavesdrop on the conversation between your computer and the web server.

    HTTPS (Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a Web protocol developed by Netscape and built into its browser that encrypts and decrypts user page requests as well as the pages that are returned by the Web server. HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer under its regular HTTP application layering. (HTTPS uses port 443 instead of HTTP port 80 in its interactions with the lower layer, TCP/IP.) SSL uses a 40-bit key size for the RC4 stream encryption algorithm,new-age browsers use 128-bit key size which is more secure than the former, it is considered an adequate degree of encryption for commercial exchange.HTTPS is normally used in login pages, shopping/commercial sites.

    Although it may be encrypted does not mean its safe, there are tools out there to decrypt the information being sent over the wire, although its more difficult to do so.

    HTTP stands for HyperText Transport Protocol, which is just a fancy way of saying it's a protocol (a language, in a manner of speaking) for information to be passed back and forth between web servers and clients.

    You really don't need to know what it all stands for; the important thing is the letter S which makes the difference between HTTP and HTTPS. The S (big surprise) stands for "Secure". You probably didn't need me to tell you that, because you already knew it had something to do with security.

    https is secure, where as http is not. simple as that

    HTTP tends to hyper text transfer protocol which is important for safely broadcasting information over the World Wide Web(WWW) and HTTPS tends to Hypertext Transfer Protocol over Secure Socket Layer or HTTP over SSL.

    HTTPS is the standard protocol used for securely transmitting data over the internet, in this case web pages. It addresses the issues with HTTP but at the same time it operates in exactly the same way, apart from the fact that all data is sent encrypted. When you visit a website with the https:// prefix you are telling the web server that you want to establish a secure communication path. HTTPS will use a different port (number 443) to ensure that all secure and non secure communications are kept separately.
