TCP/IP
TCP/IP is one of the most important elements of Internet technology an and is the element that makes intranets so easy to set up and use. The TCP/IP is actually a whole family of protocols, which provides the foundation to the Internet. TCP, meaning Transmission Control Protocol, and IP, meaning Internet Protocol, is the first thing that you can do before you can connect to the Internet or do anything with your workstations. The TCP/IP protocol was first proposed in 1973 but was not until the year 1983 when the first standardized version was developed and adopted for the wide area use. TCP/IP is made up of various but limited addresses, are set up in different classes, and can add more host addresses and separate segments in a given network by using a thing called subnet mask. A mask used to determine what subnet an IP address belongs to. An IP address has two components, the network address and the host address. The IP address is 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215) represent the Class B network address, and thesecond two numbers (017.009) identify a particular host on this network.
