What is SPAM ?

 Spam email is a form of commercial advertising which is economically viable because email is a very cost-effective medium for the sender.

How does Email works ?

Email Sender  have to use mail software called client , to compose document with attachments like pictures , audio and video files, System software called  TCP divides the message into packets and adds information about how each packets should be handled.

Internet mail address attached to each message in the form of   noah@noahfranklin.in

Mail box server converts the domain name  of the recipient's email into the numeric IP (Internet Protocol ) address .

  • First request from the "root" name server the whereabouts of other servers that store information about ".in" domains.
  • It can then interrogate the ".com" name server for the location of the specific "noahfranklin.in" name server.
