electronic device, communicating with each other via
the Internet, or
 A server running on a computer device, listening for
requests at a particular port over a network, serving
web documents.

web service between clients and servers.

 Electronic mail is a method of exchanging messages between
people using electronic devices.
 The most commonly used feature of the networks in the field of
communication is e mail.
 Invented by Ray Tomlinson, email first entered limited use in
the 1960s and by the mid 1970s had taken the form now
recognized as e-mail.
 More plainly e mail is a message that may contain text, files,
images, or other attachments sent through a network to a
specified individual or group of individuals. We can add images
and documents in the form of PDFs, videos or other
attachments.
 In order to have successful communication, each user should
have a unique email address, where each post is sent to persons
with a unique home address.
