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.
Setting Up a Smart Classroom :
You are tasked with setting up a smart classroom where different devices like projectors, smart lights, speakers, and sensors need to communicate wirelessly. The projectors will stream high-definition content, the smart lights should respond to voice commands, and the sensors will monitor temperature and motion. Considering the characteristics of Wi-Fi, Bluetooth®, and ZigBee® protocols, which communication protocol would you choose for each device in the classroom setup, and why? How would factors such as data speed, range, and power consumption influence your decisions?
Deploying a Citywide Emergency Communication System
The local government wants to establish a citywide emergency communication system that allows citizens to send distress messages and receive real-time alerts in both urban and rural areas. You need to choose between GSM (3G/4G) and 5G cellular networks. Given the differences in data speed, coverage area, and reliability, which protocol would be most suitable for urban and rural deployment? How would you ensure that the system works efficiently in both densely populated and remote areas?
Connecting Office Networks and Remote Devices In your company, office computers are connected using Ethernet for high-speed internet access. However, you need to establish a wireless connection with some remote devices located in another part of the building where running Ethernet cables is impractical. You also need to connect a few devices that communicate using infrared for short-range, line-of-sight data transfer. Based on the requirements for speed, reliability, and range, how would you combine Ethernet, infrared, and Wi-Fi protocols to ensure seamless network communication in the office? Which protocol would be most appropriate for each situation, and why?
