Ad-hoc Mode : An Ad-hoc network is a local area network
or other small network, especially one with wireless or
temporary plug-in connections, in which some of the
network devices are part of the network only for the
duration of a communications session.  Users in the
network can share files, print to a shared printer, and
access the Internet with a shared modem.  In this kind
of network, new devices can be quickly added; however,
users can only communicate with other wireless LAN
computers that are in this wireless LAN workgroup, and
are within range.
