Introducing 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 also be used to build computer networks in the home.
Ethernet, Fast Ethernet, or Gigabit Ethernet
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.
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.
Example router-based Ethernet network
The following is an example of an Ethernet network. The network is made up
of a router, your computers, and cables connecting each of these components.
The router is the central control point for the network. Attached to the router
are all of your computers or Ethernet-ready devices. Also connected to the
router is a cable or DSL modem that provides access to the Internet.
