What is the difference between HTTP and HTTPS?

HTTP Vs HTTPS Protocol

HTTP and HTTPS both are protocol use to make request to web server for website access. The below are some simple difference between both protocol that can be easily understand by students and they can have clear concept about this both protocol, so can easily write in examination of subjects such as Network Security, Internet Basics, Networking, Fundamental of Networking etc.

HTTP Protocol	HTTPS Protocol
URL of site begins with ‘http://’ for the site which uses http protocol. Example: http://www.google.com, http://www.indiastudychanel.com	URL of site begins with ‘https://’ for the site which uses https protocol. Example: https://www.facebook.com https://www.paypal.com
HTTP stands to HyperText Transfer Protocol which is not secure means the data sent via this protocol can be hacked during transition process. HTTPs is used by sites which does not require security or other way it does not doing any secure transaction. Example of such site are business site, blog, informational site etc.	Stands to HyperText Transfer Protocol via SSL which means Secure Socket Layer. HTTPS is more secure because data is encrypted before transmitting so now one can understand the data even if it hacked during transmission. Every online banking payment system uses HTTPS protocol for secure and reliable transition. Google’s Mail system also uses HTTPS for security of your mail.
It uses port 80 for internet communication.	It uses 443 for internet communication.
It operated on Application Layer of OSI protocol stack.	It operated on Transport Layer of OSI protocol stack because it deals with data encryption and decryption.
No certificate required for HTTP protocol.	There is requirement of certificate for HTTPs protocol.
No certificates required	Certificates required

The small animation given below is very helpful to understand concept of both protocol. The animation shows you how data travels on internet via physical medium in both protocol, what can be happened with data i.e hacked, destroyed, stalled and other known issues like phishing. I recommend all students who have interest in networking must see this video. The credit for this video creation goes to NetworkingForAll.
