CHAPTER 5: Networking Your Computer Introduction to networking Making sure your broadband connection works Important If you do not have a broadband connection already installed, make the necessary arrangements with your ISP. Be sure to find out how soon after the installation the line will be activated. Broadband Internet settings differ from ISP to ISP. Before you begin setting up your network, you should contact your ISP for any specific instructions they have for setting up a network. Before you change anything about your home setup, make sure that your broadband connection is working correctly. To test the connection, log onto the Internet using your current setup. If the connection is not working, contact your Internet service provider. Networking terms you should know DHCP-Dynamic Host Configuration Protocol (DHCP) lets a router temporarily assign an IP address to a computer on the network. IP Address-Internet Protocol (IP) address is a number that uniquely identifies a computer on the network. Subnet Mask-Subnet mask is a number that identifies what subnetwork the computer is located on. This number will be the same on all computers on a home network. Wired Ethernet networking An wired Ethernet network consists of two or more computers connected together through an Ethernet cable. This connection type is commonly used in offices around the world and can be used to build computer networks in the home. Ethernet, Fast Ethernet, or Gigabit Ethernet Important Check local code requirements before installing Ethernet cable or other wiring in your home or office. Your municipality may require you to obtain a permit and hire a licensed installer. Ethernet is available at three different speeds. Standard Ethernet runs at 10 Mbps, Fast Ethernet runs at 100 Mbps, and Gigabit Ethernet runs at 1000 Mbps. Most home networks are built using Standard or Fast Ethernet components. Business networks are typically built using Fast or Gigabit Ethernet components. To create a wired Ethernet network, you or your electrician must install special Ethernet cables in your home or office. Using a router The most common way to set up a wired Ethernet network is Dynamic Host Control Protocol (DHCP) using a router. A DHCP network configuration uses a router to automatically assign IP addresses to each computer or network device. For information on setting up a router, see the router's documentation. Example router-based Ethernet network The following is an example of a wired Ethernet network. The network is made up of a router, a cable or DSL modem, your computers, and cables connecting each of these components. The router is the central control point for the network. 48
