    802.11n is the latest commercially available wireless networking standard as defined by IEEE. It is generally considered to have twice the range and be 2-3 times faster than the 11g standard that preceded it. 802.11 devices let you share/connect to your network resources like other iMacs, MacBooks, iPhones, AppleTV's, printers and internet connections wirelessly.

    IEEE 802.11 is a set of standards for wireless local area networks that all recent Mac's ( and lots of computer in general ) can use to communicate with each other. The 'n' designator refers to the latest/fastest version of the 802.11 standards, other older versions had the suffix 'b' and 'g'.

    If an 802.11 base station is connected to your broadband connection (DSL, Cable etc) then it can share your internet connection with any computers in range of it that have the right password.

    The 802.11n devices use different frequency depending on the device they are communicating with (typically the 2.4, 3.6 and 5 GHz frequency bands are used). Some base stations like the current AirPort Extreme Base Station can use multiple frequencies at the same time to speed up communications when there are multiple devices on a given network.
