Using a wired Ethernet network
A 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
Install an Ethernet card in each of your desktop computers (if your 
computers do not already have built-in Ethernet jacks)
Install an Ethernet PC Card in each of your notebooks (if your notebooks 
do not already have built-in Ethernet jacks)
Install an Ethernet routerswitch, or hub
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.
Tips & Tricks
If you are connecting just two computers, you can eliminate 
the router, switch, or hub and use a special crossover 
cable.
