Peer-to-Peer

Refers to a class of systems and applications that employ distributed resources to perform a critical function in a decentralised manner. The resources encompass computing power, data (storage and content), network bandwidth, and presence (computers, human, and other resources). The critical function can be distributed computing, data/content sharing, communication and collaboration, or platform services. Decentralisation may apply to algorithms, data, and metadata, or to all of them. This does not preclude retaining centralisation in some parts of the systems and applications if it meets their requirements.
