The e-mail is a fast and important means of communication.  Person A can contact Person B across the ocean using the Internet.

E-mail is the most common form of communication on the Internet. It is coded and un-coded as it traverses the distance and goes through the process which is illustrated below.527px-Email.svg

Alice at alice@a.org sends an e-mail to Bob at bob@b.org. To get there, the e-mail first goes through a the Submission Protocol (smpt.a.org) which sends it to the Domain Name System for domain name verification, which sends it back to the Submission Protocol, which gives it to the Message Transfer Agent (mx.b.org) which gives it to Bob. That is the process of the e-mail.
