Answer :
Final answer:
Switches analyze and route data packets to specific devices using MAC addresses, while hubs simply broadcast the data to all connected devices. Hubs do not perform any computing functions, whereas switches do. This key difference makes switches more efficient in managing network traffic.
Explanation:
Difference Between Switches and Hubs
In computer networking, switches and hubs are both crucial devices for connecting multiple computers within a network, but they operate in fundamentally different ways.
Switches are intelligent devices that operate at the data link layer (Layer 2) of the OSI model. They analyze the MAC (Media Access Control) addresses in the packets they receive and use this information to route data specifically to the intended recipient on the network. This means that switches can manage traffic efficiently, reducing the chance of collision and enhancing the overall performance of the network.
In contrast, hubs are simpler devices that operate at the physical layer (Layer 1) of the OSI model. Hubs broadcast data to all connected devices in the network, which means they do not have the ability to filter or direct traffic. As a result, all data packets received by a hub are sent out to every port, leading to potential network congestion and inefficiencies.
To summarize, the main difference between these two devices is that hubs do not engage in any kind of computing while switches do. This helps explain why switches are preferred in more complex networking environments.
