Briefly explain how an email is used as a means of communication.

What will be an ideal response?

Answers will vary. An email message is a message sent between individuals over a network-usually the Internet. Email is one of the most widely used Internet applications-Americans alone send billions of email messages daily-and email sent via a mobile device is growing at an astounding rate. You can send an email message from any Internet-enabled device, such as a desktop computer, portable computer, or smartphone, to anyone who has an Internet email address.?To contact someone using the Internet, you most often use his or her email address. An email address consists of a username (a unique identifying name), followed by the @ symbol, followed by the domain name for the computer that will be handling that person's email (called a mail server). Please see the section "Computer Networks and the Internet" for more information.
