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.
     
    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 grief).
