Case 1:

What is a characteristic of a peer-to-peer application?

• Each device using the application provides a user interface and runs a background service.
• Each device can act both as a client and a server, but not simultaneously.
• The resources required for the application are centralized.
• One device is designated a server and one device is designated a client for all communications and services.

Explanation: Peer-to-peer networks exist directly between client devices, with no centralized resources or authentication. Hybrid peer-to-peer systems also exist that decentralize resource sharing but can use centralized indexes to point to the resource locations.

Case 2:

What is a characteristic of a peer-to-peer application?

• Both host devices load a user interface and the same background service during the communication.
• It can only be used on a peer-to-peer network.
• Peer-to-peer application developers typically provide their own transport layer protocol for their applications.
• The host who initiates the communication becomes the client and the other host becomes the server.

Explanation: A peer-to-peer (P2P) application requires that each end device load a user interface and run the same background service. In P2P, a host acts as both a client and a server within the same communication. Every client can initiate a communication and both sides are considered equal in the communication process. P2P can be used on peer-to-peer networks, client/server networks, and across the Internet.
