What is a primary difference between a hub and a switch?

• A. A hub forwards data only to specific devices
• B. A switch broadcasts data to all ports
• C. A hub broadcasts data to all ports
• D. A switch only connects devices without forwarding data

Answer: (C)

The primary difference between a hub and a switch lies in how they manage and direct data traffic on a network. A hub functions as a basic networking device that simply receives incoming data packets and broadcasts them to all connected devices without determining the destination. This means that any device connected to the hub receives all the data being transmitted, regardless of whether or not it is the intended recipient. This characteristic can lead to network inefficiencies and increased collisions, as multiple devices may attempt to communicate simultaneously. In contrast, a switch is designed to intelligently manage data traffic. It examines the incoming data packets and directs them specifically to the intended device based on its MAC address. This targeted approach ensures that only the relevant recipient receives the transmitted data, optimizing network performance and reducing potential data collisions. Therefore, the statement about a hub broadcasting data to all ports accurately represents its fundamental function. A switch operates differently by forwarding data only to specific devices, enhancing network efficiency and security.
