Defining the Peer-to-Peer (P2P) Model
What is the P2P Model?
- Definition: The Peer-to-Peer (P2P) network model is a decentralized architecture where each device (peer) functions as both a client and a server, directly sharing resources like files, printers, or internet bandwidth without a central server.
- Characteristics:
o No dedicated servers; all devices are equal peers.
o Direct communication via IP addresses or protocols (e.g., SMB, BitTorrent).
o Typically used in small networks (e.g., 2–10 devices).
- Operation:
o Peers discover each other via network protocols or manual configuration.
o Resources are shared locally (e.g., shared folders) or globally (e.g., P2P file-sharing apps).
- Example: Two PCs in a home share a printer via a P2P network, with one PC hosting the printer and the other accessing it.
Key Components
- Devices: PCs, laptops, or IoT devices acting as peers.
- Network Protocols: SMB/CIFS for file sharing, UPnP for device discovery.
- Software: P2P applications (e.g., BitTorrent, Windows file sharing).
- Connectivity: Ethernet, Wi-Fi, or ad-hoc wireless for peer communication.
- Example: A small office uses Windows file sharing over Ethernet to create a P2P network for document exchange.
Exam-Relevant Definition
- Advantage: Cost-effectiveness—P2P networks require no dedicated server hardware or complex administration, reducing setup and maintenance costs.
- Incorrect Options:
o High scalability: Better suited for client-server models.
o Centralized management: Not applicable to P2P’s decentralized nature.
o Enhanced security: P2P lacks robust centralized controls.
- Example: A study group sets up a P2P network to share lecture notes, avoiding the cost of a server.
N10-008 Relevance: Questions may test P2P definitions or advantages. Study4Pass flashcards emphasize cost-effectiveness for quick recall.
