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 router, switch, 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 (known as a
peer-to-peer wired Ethernet network), you can eliminate
the router, switch, or hub and use a special crossover
cable.
