Most laptop computers and many desktop computers are sold with a wireless adaptor built-in. The wireless adaptor enables the computer to access a wireless network by receiving the radio signal from the network's wireless router. If you are not sure if your computer has a wireless adaptor installed, you can use the "Device Manager" utility in Windows to view if there is one installed, before purchasing an external wireless adaptor to access your network.
