What type of network allows devices to share resources without a dedicated server?
(A) Peer-to-Peer (B) Mesh (C) Client-Server (D) Ring
The correct answer and explanation is:
The correct answer is (A) Peer-to-Peer.
In a Peer-to-Peer (P2P) network, devices (or “peers”) are connected in such a way that they can share resources, such as files, printers, or internet access, directly with one another without the need for a dedicated server. Each device on the network can act both as a client and a server, meaning that any device can request resources from another device, or provide resources to others.
A key characteristic of a P2P network is its decentralized nature. Unlike Client-Server networks, where a central server handles requests and resources, a Peer-to-Peer network allows all devices to be equally responsible for both providing and receiving data. This makes it cost-effective because no central server is required to manage the network. Peer-to-Peer networks are often used in smaller setups, such as home or small office environments, where the need for complex server management and centralized control is minimal.
In a P2P network, there is no single point of failure, which can increase reliability. However, this also means that the management of resources is often more distributed and less controlled. Security concerns can also arise, as each device is directly accessible by other devices, which can expose the network to potential threats if not properly managed.
On the other hand, Client-Server networks are centralized and require a dedicated server to manage resources and requests, Mesh networks involve interconnected devices, and Ring networks involve devices connected in a circular fashion, both of which are distinct from P2P networks.
