Access Point -
A device that allows wireless-equipped computers and other devices to
communicate with a wired network. Also used to expand the range of a wireless network.
Ad-hoc Network -
An ad-hoc network is a group of computers, each with a wireless adapter,
connected as an independent IEEE 802.11 wireless LAN. Ad-hoc wireless computers operate on
a peer-to-peer basis, communicating directly with each other without the use of an access point.
Ad-hoc mode is also referred to as an Independent Basic Service Set (IBSS) or as peer-to-peer
mode, and is useful at a departmental scale or SOHO operation.
