                  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. It's considered a reliable and legal method
                  of communication. 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.
