Chapter 7: 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.

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.
