  @bill
  i also googled it out but my question is that why do only some sites have https and some has http
  
  for example when we login into orkut the site is first https but when we get completed that is we are on our home page then its http.....
  why???

  https is secure or encrypted.
  
  That means someone monitoring your message would not be able to see what you were typing.
  
  So if you are entering a password or your credit card information, you would want this to be done via https.
  
  If it is a regular http connection and you enter a password (and the password is Engineer), then it would look like this to someone monitoring your connection...
  Engineer
  
  If it is https, then it might look something like this...

  Also encrypting and disencrypting messages takes a lot of computer power.
  
  So they will have you login with https, then switch to http (less computer power) to do things which do not need to be encrypted.
  
  Or you may look at something to buy with http pages, then when you go to buy it, they switch to https so you can enter your credit card information, etc.
