Every computer on a network is called a node, a workstation, a PC or a network computer. While there are many names for a computer, computers and other devices communicate using the TCP/IP protocol. Simple put, computers use a language much like we do in order to communicate with one another.
The primary language for computers is a protocol known as TCP/IP. TCP, or Transmission Control Protocol, insures that packets of data get to their destination and IP, or Internet Protocol, routes the packets of data to their destination. This can be compared to the pilot of a plane and a navigator.
Where do you get your IP address? Servers and devices issue IP addresses based on numbers that a network administrator puts in a DHCP server. DHCP Servers can be complex computers that give out numbers for your computer or simple devices such as routers in your home that are set up to give out numbers so your computers can communicate.
While there are millions of combinations of numbers that are given out based on the complexity of a network, home users may only receive a number from their internet service provider or a number given by their home router.
