Which device is commonly used to connect multiple devices to a network?

• A. Router
• B. Hub
• C. Switch
• D. All of the above

Answer: (D)

The correct response highlights that all listed devices serve the purpose of connecting multiple devices within a network. Each device plays a different but essential role in network operation and management. A hub is a basic networking device that connects multiple Ethernet devices, making them act as a single network segment. It is often used in small networks. However, hubs broadcast data to all connected devices, which can lead to collision and inefficiencies. A switch is more advanced than a hub, operating at the data link layer. It connects devices more intelligently by filtering and forwarding data only to specific devices, thus reducing collisions and improving network efficiency. A router connects multiple networks and directs data packets between them. It can manage traffic between home networks and the internet, assigning IP addresses and providing firewall capabilities. Since routers, hubs, and switches all facilitate connections among multiple devices, the selection of all three as the correct answer reflects their collective relevance in constructing and maintaining network infrastructures.
