Wireless (Wi-Fi)

Routers are better known as intermediary devices that enable computers and other network components to communicate or pass information between two networks e.g. between your home network and the Internet. The most astounding thing about routers is their capability to direct network traffic. Routers can be wired (using cables) or wireless. Routers also typically provide built-in security, such as a firewall.

Access points provide wireless access to a wired Ethernet network. An access point plugs into a hub, switch, or wired router and sends out wireless signals. This enables computers and devices to connect to a wired network wirelessly. You can move from one location to another and continue to have wireless access to a network. When you connect to the Internet wirelessly using a public wireless network in an airport, hotel or in public, you are usually connecting through an access point. Some routers are equipped with a wireless access point capability, in this case you don’t need a wireless access Point.
