Computer and Internet (Q&A)

Answer:

An ad-hoc network is a sort of temporary LAN that is built spontaneously as devices connect. Instead of relying on a base station to coordinate the flow of messages to each node in the network, the individual network nodes forward packets to and from each other. It is generally established for a single session and does not require a router  or a wireless base station. For example, if you need to transfer a file to your friend's laptop, you might create an ad hoc network between your computer and his laptop to transfer the file. This may be done using an Ethernet crossover cable, or the computers' wireless cards to communicate with each other. If you need to share files with more than one computer, you could set up a multi-hop ad hoc network, which can transfer data over multiple nodes.
