(a) The diagram shows a client-server network model.
Describe the role of the server in a client-server network.
[2]
(b) State two examples of services that the server might provide to the clients.
[2]
(c) Compare client-server and peer-to-peer network models. State two differences.
[4]
Answer Details
(a) The server in a client-server network is a central, powerful computer that manages and provides resources and services to the connected client computers. [1] It processes requests sent from clients (such as asking for a web page, a file, or authenticating a user) and sends back the appropriate responses. [1]
(b) Two examples of services a server might provide:
- File storage and sharing: the server stores files centrally and provides access to clients who need them. [1]
- User authentication: the server manages usernames and passwords, verifying the identity of users before granting them access to network resources. [1]
(c) Two differences between client-server and peer-to-peer networks:
- In a client-server network, there is a dedicated server that manages resources and handles requests; in a peer-to-peer network, all computers are equal and each can act as both a client and a server, sharing resources directly with one another. [2]
- In a client-server network, data and security are managed centrally on the server, making administration easier; in a peer-to-peer network, data is distributed across all nodes and each user is responsible for their own security, making central management difficult. [2]
