Question

what is peer - to - peer architecture?
a system where one central server controls all data
a system where every device can act as both a client and a server
a type of internet connection used only by large corporations
a method of encrypting data

Explanation:

Peer - to - peer architecture is a distributed network model. In this model, there is no central server. Each device (peer) has equal capabilities. It can request resources (act as a client) and also provide resources (act as a server).

• Option A: A system with a central server controlling all data is a client - server architecture, not peer - to - peer.
• Option B: In peer - to - peer architecture, every device can act as both a client and a server. For example, in a peer - to - peer file - sharing network, one user can download a file (client) and also share their own files (server).
• Option C: Peer - to - peer is not just an internet connection for large corporations. It can be used in various scenarios like small - scale local networks or global file - sharing.
• Option D: Encrypting data is a security measure, not the definition of peer - to - peer architecture.

Answer:

B. A system where every device can act as both a client and a server
