7. What is meant by HTTP and HTPPS in website URL's?

http (Hypertext Transfer Protocol) is a system for transmitting and receiving information across the Internet. It is a simple request, and a response procedure is followed on the internet so that information can be easily, accurately and quickly exchanged between servers and software's which are trying to access it.

For clients who exchange confidential information with a server, a need for security was felt to prevent unauthorized access hence, https, or secure http, was developed by Netscape Corporation to allow authorization and secured transactions.

As you see the main difference between http:// and https:// is added security. The 's' stands for "Secure" in the url. Check your bank website or any transaction site and it will most likely begin with: https://.

Therefore make sure that you never ever enter your credit card details in an http website! If the url begins with an https:// it means you are connected to the website in a secure mode and your data is safe.
