Chapter 5: Networking Your Computer

Introduction to Networking
An 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 an 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 an 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 an 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
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.
Tip
To add the ability to access a wireless Ethernet network to your wired Ethernet
network, connect an access point to the router or use a router that has a built-in access point.
