What is the primary function of a client-server model?

• To separate client requests from server responses, enabling resource sharing and management.

• To combine client and server functions into a single application.

• To eliminate the need for resource management in networked applications.

• To enhance server performance by reducing client requests.

In a peer-to-peer network, how do devices communicate with each other?

• Devices use email to send messages to each other.

• Devices communicate through a central server.

• Devices require a dedicated network cable to connect.

• Devices communicate directly with each other using peer-to-peer protocols.

What is an ad hoc network and when is it typically used?

• A permanent network established using routers and switches.

• A network that only allows wired connections between devices.

• A type of network that requires a central server to function.

• An ad hoc network is a temporary wireless network formed by devices connecting directly to each other, typically used when no fixed infrastructure is available.

What is tethering and how does it work in mobile devices?

• Tethering is the process of sharing a mobile device's internet connection with other devices.

• Tethering is the process of transferring files between mobile devices.

• Tethering is a method of charging mobile devices.

• Tethering refers to connecting multiple mobile devices to a single charger.
