Network adapters overview

A network adapter is a device that connects your computer to a network.

External network adapters do not require opening up your computer or installing special network cables in your home. You can plug an external network adapter into a USB port on your computer. External network adapters are the fastest and easiest way to set up your home network. They are available for Ethernet, home phoneline network adapter (HPNA), or wireless technology.

Internal network adapters are installed in an expansion slot inside your computer. Most computers come with several PCI expansion slots.
