Email addresses are similar to URLs, but they are simpler. They consist of two parts. The first part is the name of the person. This is followed by the @ sign. The @ sign is followed by the domain name of the Internet server you use. If you have chosen marysmith as your name and you use AOL, your email address will be email@example.com. If you use a company Internet server, your address will be firstname.lastname@example.org. If you have your own website named smithfamily.com, your address would be email@example.com. As with URLs, email addresses contain no spaces, but can contain uppercase letters.
