What is the difference between http and https?

What is the difference between http and https ?
Time to know this with 32 lakh debit cards compromised in India.
Many of you may be aware of this difference, but it is
worth sharing for any that are not.....
The main difference between http:// and https:// is all
about keeping you secure 
HTTP stands for Hyper Text Transfer Protocol
The S (big surprise) stands for "Secure".. If you visit a
Website or web page, and look at the address in the web browser, it is likely begin with the following: http:///.
This means that the website is talking to your browser using
the regular unsecured language. In other words, it is possible for someone to "eavesdrop" on your computer's conversation with the Website. If you fill out a form on the website, someone might see the information you send to that site.
http and https 
This is why you never ever enter your credit card number in an
Http website! But if the web address begins with https://, that
means your computer is talking to the website in a
Secure code that no one can eavesdrop on.
You understand why this is so important, right?
If a website ever asks you to enter your Credit/Debit card
Information, you should automatically look to see if the web
address begins with https://.
If it doesn't, You should NEVER enter sensitive
Information....such as a credit/debit card number.
PASS IT ON (You may save someone a lot of http and https grief).
