What common feature distinguishes a network switch from a hub?

The distinctive feature that sets a network switch apart from a hub is its ability to filter and forward data to the correct device. This capability is rooted in how switches manage data traffic within a network. When a switch receives a data packet, it examines the destination address contained in the packet. Using its MAC address table, the switch can identify which device is associated with that address and forward the packet specifically to that device. This targeted approach reduces unnecessary network traffic and enhances overall efficiency, making it an essential component in modern networking.

In contrast, hubs operate on a more basic level by broadcasting incoming packets to all connected devices regardless of the intended recipient. They do not have the intelligence to direct packets where they need to go, leading to more collisions and congestion on the network.

The other options point to features that do not accurately characterize a switch. For instance, a switch does not lack reliability compared to a hub; in fact, it is generally considered more reliable because of its ability to manage traffic effectively. Lastly, switches can operate over wired connections and, in some cases, alongside wireless connections, contrary to the implication that they are limited to wireless operations. Thus, the ability to filter and forward data accurately defines the advanced functionality of a switch compared to a basic
