PC Card – Wireless functionality can be added to notebook computers through the use of a removable network card which is inserted into a type 2 or 3 cardbus slot.

MiniPCI- Wireless functionality that is embedded onto the motherboard of the computer, typically installed at the factory, and is not removable or upgradeable.

PCI Card - Wireless card that is installed in the PCI bus slot inside desktop PCs.

USB – Universal Serial Bus (USB) interface cards connect notebook and desktop computers to wireless networks via the client’s USB port, rather than utilizing either embedded mini-PCI or removable PC cards.

Access Point (AP) – Wi-Fi enabled computers typically connect to wired networks by means of an access point, a wireless device whose primary function is to consolidate multiple wireless connections, serving as an intermediary between wireless devices and high-speed wired networks. Access points are connected to a wired network with an Ethernet cable..

Router – Wireless routers provide the same functionality as access points, but include the added features of allowing multiple users to share a wide area connection to a broadband modem-providing multiple IP addresses, firewall capabilities, and hub and switching functionality.

Print Server – A wireless print server allows multiple computers and other Wi-Fi enabled devices to share a printer without the use of cables. Print servers are typically connected via parallel or USB port to the printer, and allows files to be transferred wirelessly for printing.

Broadband Modem – Broadband modems act as gateways for high speed network access in the home and small business, facilitating a broadband connection through cable or DSL connection. Some broadband modems are beginning to incorporate Wi-Fi capabilities, replacing the need for an access point or router.

Wireless Ethernet Transceiver (WET) or Bridge - Allows you to convert an Ethernet- based device into a wireless device by connecting the wireless transceiver/bridge to an Ethernet Port.

Repeater – A wireless repeater increases the range of a wireless network by receiving signals from an access point or router, amplifying them, and then re-broadcasting them with more power.
