TCP/IP

This section is intended to provide information to help you gain a basic understanding of TCP/IP.

Similar to a common language that people use to communicate with each other, TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of protocols designed to define the way computers and other devices communicate with each other over a network.

TCP/IP is rapidly becoming the most used set of protocols. The main reason this is happening is the fact that the Internet is based on TCP/IP. If you have a network that you wish to connect to the Internet, you must be using TCP/IP to communicate.

This section provides information about the following topics:

• Internet Protocol (IP)
• Transmission Control Protocol (TCP)
• User Datagram Protocol (UDP)
• IP address
