Exploring Computer Network Models

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.

Which wireless protocol is commonly used for home networking?

• NFC

• Bluetooth

• Zigbee

• Wi-Fi

What is the main advantage of using ZigBee® in IoT applications?

• Limited device compatibility and proprietary protocols.

• High data transfer rates and long-range connectivity.

• Complex setup and high maintenance costs.

• Low power consumption and mesh networking capabilities.

How does Bluetooth® differ from Wi-Fi in terms of range and use cases?

• Bluetooth® has a longer range (over 30 meters) and is used for internet access.

• Wi-Fi is primarily for personal device connections and has a shorter range (about 10 meters).

• Bluetooth® has a shorter range (about 10 meters) and is used for personal device connections, while Wi-Fi has a longer range (over 30 meters) and is used for internet access and networking.

• Bluetooth® can connect to multiple devices simultaneously, while Wi-Fi cannot.

What are the key features of GSM technology in cellular networks?

• No support for SMS

• Key features of GSM technology include digital transmission, TDMA, FDMA, SMS support, security encryption, and roaming capabilities.

• Analog transmission

• CDMA only support

What advancements does 5G technology bring compared to 4G?

• 5G provides faster speeds, lower latency, greater device capacity, and improved support for IoT and advanced applications.

• 5G has slower speeds than 4G

• 5G does not support IoT devices effectively

• 5G reduces device capacity compared to 4G

What is the role of Ethernet in wired networking?

• Ethernet facilitates communication and data transfer in wired networking.

• Ethernet is a type of software for managing networks.

• Ethernet only connects devices to the internet.

• Ethernet is used for wireless communication.
