Which model allows for decentralized data sharing among devices?

The peer-to-peer model is designed to enable decentralized data sharing among devices. In a peer-to-peer architecture, each device, or node, can act as both a client and a server. This means that every participant in the network can directly share resources, such as files or applications, without the need for a central server.

This model promotes a collaborative environment where devices can connect and exchange information freely, making it ideal for scenarios that require efficient data sharing among connected devices, such as file sharing applications or decentralized networks. The independence from a central authority not only enhances resilience and scalability but also allows for more fluid and egalitarian data sharing practices.

In contrast, the client-server model relies on a centralized server to manage requests and share data with clients. The extranet refers to a controlled private network allowing access to partners, vendors, or suppliers, further emphasizing its reliance on central management. A hybrid model combines elements of both centralized and decentralized approaches but does not prioritize decentralized sharing as the primary function. Thus, the peer-to-peer model stands out as the best choice for enabling fully decentralized data sharing.
