    Hiya,
    I apologise for what may seem as a daft question...I'm working through the ECDL and don't understand LAN / WAN ??
    I've goggled for information but remain befuddled...is LAN a computers network shared within a building - does this exclude the internet? and computers connected to the internet on WAN?
    Sorry all...I feel stupid asking but trying to find an answer is driving me bonkers.
    Thanks x

    LAN is a local area network,which would be something like your
    personal home network or an internal network at a business.

    WAN is a wide area network.
    The internet is actually a wan.
    A wan can connect to other networks outside the LAN.
    Businesses can have their own wan that connects to other locations
    outside their LAN.
    This is a basic description,not comprehensive,but should give you
    the basic idea.
