Protocol dictates the correct way to address a foreign dignitary, such as "Her
Excellency the Right Honorable…" These strict rules of etiquette ensure
that no one is inadvertently offended when meeting people of different cultures.
In the online world, protocols make it possible for different types of computers
- Macintosh, PC, UNIX - to communicate with each other as well. They are standards or
rules that enable one computer to understand messages sent from another and then act on
those messages. There are many protocols for communicating on the Internet.
Some common ones are:
- Simple Mail Transfer Protocol (SMTP) - send and receive email
- File Transfer Protocol (FTP) - transfer files between computers
- Hypertext Transfer Protocol (HTTP) - transmit information on the Web
Without protocols, computers would have no idea what to do with our email messages
or how to display a Web page.
