Hypertext - the organization of information units into connected associations. An instance of such an

association is called a "link," "hypertext link," or "hyperlink."

Internet - a worldwide system of computer networks - a network of networks in which users at any one

computer can get information from any other computer.

Internet mail address - a string of bytes containing the character @. Basically, the address is in the

format: mailbox@domainname The mailbox part is everything before the @ symbol and the domain name

part of an address is everything after the final @. For example, the address: [email protected].

Some domains have owners. It is up to the owner to say how mail messages will be delivered to

addresses within the domain. If you are administering your server as a LAN with other users, here are

some suggestions on choosing mail addresses for the Internet:

• Do not use non -ASCII characters.

• Do not use ASCII control characters such as: \0 , \012 and \015.

• Avoid spaces, backslashes, double quotes, <, >, brackets, parentheses, semicolons, commas,

and colons.

• Do not use @ in the mailbox part.

• Do not use two consecutive dots, a dot at the beginning, or a dot at the end in the mailbox part.

• Do not use an empty mailbox part.

• Do not use two consecutive dots, a dot at the beginning, or a dot at the end in a domain name.

• Avoid mailbox parts longer than 64 characters.

• Avoid uppercase letters in box parts.

• Avoid the following characters: $ & ! # ~ ' ^ * |

• Avoid underscores as many hosts have trouble with other them.

• Avoid domain names longer than 64 characters.

• In domain names, stick to letters, digits, dashes, and dots.

• As for Global box parts and the use of Postmaster, consult RFC 822 and RFC 1123 for detailed

information.

computers on the Internet.

ISP; Internet Service Provider - a company that provides individuals and companies access to the

Internet and other related services such as Web site building and virtual hosting. An ISP has the

equipment and the telecommunication line access required to have POP (point -of-presence; an access

point to the Internet) on the Internet for the geographic area served.

IMAP; Internet Message Access Protocol - a protocol for receiving email. An IMAP Server is an

application that runs the IMAP service. With IMAP the email messages remain stored on the server when

they are delivered to the client computer, allowing you to access the same message from many locations

even after reading it. Contrast POP (first definition).

Jabber - an open standard instant -messaging protocol, which allows two or more people to type

messages to each other across the Internet at a faster pace than email allows. Each person needs a
