                  E-mail

                  An Electronic mail or e-mail can be defined as the process of exchanging messages electronically
                  through a communication network by using computer. Although, an e-mail is usually associated
                  with the Internet, it is not necessary to have an Internet connection to send and receive e-mails.
                  Many organisations have e-mail facilities within their own networks, without having an Internet
                  connection.
