In a peer-to-peer (P2P) network, what is the primary characteristic that differentiates it from other types of networks?

• One central server manages all data and resources.

• All computers have equal permissions and responsibilities for processing data.

• Only one computer is responsible for managing network traffic.

• Data processing is controlled exclusively by network administrators.

In the client-server model, what is the main role of the server in the network?

• To ensure all clients have equal responsibilities for processing data.

• To store data, manage resources, and control user access.

• To act as a peer among all other computers with equal permissions.

• To restrict network access to only one user at a time.

Which of the following is an advantage of a peer-to-peer (P2P) network?

• Requires more hardware than client-server models.

• Easier to set up and does not require a dedicated server.

• Provides a central location for data storage.

• Offers enhanced security compared to client-server models.

What is a disadvantage of a peer-to-peer (P2P) network?

• It allows for easy scalability.

• It provides a central location for data storage.

• It typically has less security than the client-server model.

• It requires specialized hardware for setup.

Which of the following is an advantage of the client-server model?

• It requires less maintenance than peer-to-peer networks.

• Centralized servers provide better stability and security.

• All clients have equal control over data storage.

• It is typically less expensive to set up.

What is a disadvantage of the client-server model?

• It allows for easy integration of new technologies.
