The key difference between hub and bridge is that hub works on the physical layer, but bridge runs on the data link layer of OSI model. Hubs and bridges have different uses. Hubs send data to each device connected to them, and it broadcasts data. On the other hand, the bridge is more intelligent, checking and filtering data before forwarding data. This mechanism can significantly reduce network traffic and improve security. Hubs can connect two LAN segments, while bridges can connect two different LANs. Differences between Hubs and Bridges BASIS FOR COMPARISON HUB BRIDGE Basics Used to connect a number of devices. Facilitates in the segmentation of the larger network. Types Active and Passive Transparent, translational and source route. Data filteration Not performed Conducted Uses Multiple ports Single incoming and outgoing port Links Segments of LAN Two different LAN employing same protocol. What is the hub? Hub is a basic network device because it provides a very simple function of establishing connections between several devices. In addition, the device can also be used as a connector for different LAN segments. These devices are connected to the hub by twisted pair cables. The main purpose of hubs is to transmit data packets to each device connected to them. It does not perform any filtering, which means that each block of data is transmitted to all connected terminal devices, even if it is not the target device. That's why it's considered a non-intelligent device. Hubs work in a single conflict area, which means that transmission lines should run at the same speed.…
