TCP/IP defines the language that your computer uses to communicate with other computers. We recommend using automated Dynamic Host Configuration Protocol (DHCP) to automatically assign Internet Protocol (IP) addresses to the computers on your network, if your network supports it. If you use DHCP, then you don't have to change your settings if you move your computer to another location, and DHCP doesn't require you to manually configure settings such as Domain Name System (DNS) and Windows Internet Name Service (WINS).
