Social peer-to-peer processes are interactions with a peer-to-peer dynamic. These peers can be humans or computers. Peer-to-peer (P2P) is a term that originated from the popular concept of the P2P distributed computer application architecture which partitions tasks or workloads between peers.[better source needed] This application structure was popularized by file sharing systems like Napster, the first of its kind in the late 1990s. The concept has inspired new structures and philosophies in many areas of human interaction. P2P human dynamic affords a critical look at current authoritarian and centralized social structures. Peer-to-peer is also a political and social program for those who believe that in many cases, peer-to-peer modes are a preferable option.
