Final answer:
The false statement about peer-to-peer software is that P2P networks rely on a central server. P2P networks are decentralized, facilitate direct communication between users, and file sharing is a common use.
Step-by-step explanation:
The statement that is not true about peer-to-peer (P2P) software is 'P2P networks rely on a central server.' P2P networks are designed to be decentralized, meaning they do not depend on a central server to facilitate the communication and sharing between users. Instead, each peer in the network acts as both a client and a server, sharing resources and communicating directly with other peers. File sharing is indeed a common use of P2P software, and one of the defining features of P2P is that it allows direct communication between users.
