Wireless Adaptor

A wireless adaptor, which contains a built-in radio transmitter and receiver, enables a computing device to join a wireless local area network. It supports one or more of the 802.11a, 802.11b, 802.11g, and 802.11n WiFi standards.

Traditional PCI wireless adaptors are add-in cards which are installed inside a desktop with a PCI bus. The USB wireless adapter is connected to the external USB port of a computer. In addition, the so-called PC Card or PCMCIA wireless adapter is inserted into a narrow open bay on a laptop. Each of the above wireless network adapters is small, generally less than 0.15 meters in length. Each provides equivalent wireless capabilities according to the WiFi standard it supports.

Many laptops today are manufactured with built-in wireless networking modules. Small chips inside the laptop provide the equivalent functions of a network adaptor. For these laptops, installing a separate wireless network adapter is obviously unnecessary.
