FILE SHARING
Exchanging files and other data has become very common among internet users. All kind of files ans software applications are being shared all the time.
To do this, users normally use Peer2Peer (P2P) programs such as eMule, Ares or BitTorrent.

SOCIAL NETWORKS
Social networks are virtual spaces where users with common needs, interests or concerns can participate,communicate and share resources.
Members of these sites can invite people they know to join the network, and, in turn, these new members can invite their family, friends and colleagues to join too. In this way, the number of participants can grow very quickly.
You have to be invited to join some networks, but others are open to everyone.
