What is an example of Peer-to-Peer (P2P)?
Correct Answer
Skype
Explanation
Skype is an example of Peer-to-Peer (P2P) technology because it allows users to communicate directly with each other without the need for a central server. In a P2P network, each participant can act as both a client and a server, sharing resources and information with other users.
