Wi-Fi Device

Short for Wireless Fidelity, Wi-Fi utilizes one of the IEEE 802.11 wireless standards to achieve a wireless connection to a network. A home wireless network uses a wireless access point or router to broadcast a signal using WAP or WEP encryption to send and receive signals from wireless devices on the network. The picture shows a Wireless access point with two antennas and an example of how most home users connect to the Internet using a wireless device.

If the desktop computer or laptop does not have wireless it requires a wireless adapter in order to connect to the wireless network. Below are examples of the different Wi-Fi adapters that can be used with a computer to connect to a wireless network.

In the picture above, the first image is of a Linksys desktop Wi-Fi card that connects to a PCIslot on the motherboard. Next, the SMC wireless PC Card is used with older laptops that do not have a wireless option. Finally, the far right picture is of a Cisco USB Wi-Fi adapter that can be used on any computer with a USB port
