CHAPTER 9: Networking Your Computer

Introduction to Networking
Making sure your broadband connection works
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
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.
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
.
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.
