TCP/IP essays TCP/IP is one of the most important elements of Internet technology 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 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 the second two numbers (017.009) identify a particular host on this network. Subnetting enables the network administrator to further divide the host part of the address into two or more subnets. A part of the host address is reserved to identify the particular subnet. This is easier to see if you show the IP address in binary format or not. The full address is: 10010110.11010111.00010001.00001001 The Class B network part is: 10010110.11010111 and the host address is 00010001.00001001 Every machine on the Internet has a unique identifying number, called an IP Address. A typical IP address looks like this: 216.27.61.137 To make it easier for us to remember, IP addresses are normally expressed in decimal format as a dotted decimal number like the one above. But computers communicate in binary form. Look at the same IP address in binary: 11011000.00011011.00111101....
