Wireless networks typically work in one of two configurations (sometimes called topologies): ad-hoc or infrastructure. The topology or mode you choose depends on whether you want your PCs to communicate directly or with an access point . In ad-hoc mode data in the network is transferred directly to and from wireless network adapters connected to PCs. A ad-hoc network is also called a peer-to-peer network .

A technology used to transfer data wirelessly . Bluetooth is found in PDA's and cell phones and can be used to transfer data to laptop and desktop computers and printers . Like 802.11b networking equipment , Bluetooth operates in the 2.4GHZ band , does not require line of sight between components , and can pass through walls .

A firewall on your network puts a layer of protection between you and a hacker. Firewalls can be software you install on a computer, or they can be built into a router , or used as a standalone firewall hardware device. Whether you decide to install software or hardware , a firewall will help keep outsiders from accessing your network .

This hardware device is used to connect multiple wired elements of your network , including computers or routers, to your network. A hub has ports , usually four or more , into which you can plug network cables. A access point works a bit like a wireless hub , and connects a wireless network to a wired network.

You can increase the range of your wireless network by adding a access point . Wireless networks that use a access point are operating in infrastructure mode rather than ad-hoc mode , where the network adapters communicate directly with each other.
