What is a feature of a hub that can contribute to data collisions?

A hub operates at the physical layer of the OSI model and is designed to connect multiple devices within a network. One of the primary characteristics of a hub that can lead to network issues, including data collisions, is its multiple ports.

When data is transmitted across a hub, any signal sent from one device is broadcasted to all other connected devices through its ports. This means that if two devices try to send data simultaneously, the signals can collide, resulting in a data collision. Since a hub does not have the ability to manage or separate the traffic directed toward each connected device, it inherently leads to increased chances of collisions, especially as more devices are added to the network.

In contrast, features like smart capabilities, packet filtering, and isolation of traffic are associated with more advanced networking devices such as switches and routers. These functions help manage data flow and reduce collisions by directing data packets specifically to their intended destinations or segmenting traffic, thus providing a more efficient network environment.
