Peer to Peer Networking (P2P) is a distributed application in Information Systems which has become increasingly popular over the past few years. It occurs when two or more PCs are connected and simply allows users to easily share resources such as files with one another without the need of third parties being involved (i.e without going through a central server). Below is a diagram which may help you visualize the process of a P2P Network:
One example of a P2P network which some of you may be familiar with is Bit-Torrent. This allows many users to share files such as movies, e-books and music with one another quickly and efficiently. Skype is another example of P2P Networking as it allows people to communicate with each other over the internet through instant messaging and video calls.
Essentially P2P networking is a highly effective and efficient way of sharing resources with one another online, and is a trend in I.S which will continue to evolve in the future.
Eternal Sunshine of the IS Mind 
nice and interesting, especially the diagram
Really interesting:) great use of diagrams:) I like how you picked one aspect of trends in IS
I also liked the way you choose one trend in information systems instead of giving a broad overview, very clear and well written, good use of a diagram.
