WebA hub serves as a central point to which all of the hosts in a network connect to. A Hub is an OSI Layer 1 device and has no concept of Ethernet frames or addressing. It simply receives a signal from one port and sends it out to all other ports. Here is an example 4-port Ethernet hub (source: Wikipedia): Web27 Dec 2024 · A Hub works on the physical layer (layer 1) of the OSI model, so, it cannot process layer-2 or layer-3 traffic and it cannot process information based on MAC or IP addresses. The Unmanaged switch is a data link layer device (layer 2). It records the MAC addresses of the computers connected to it in a tabular format.

WebIt works at the Physical layer (layer 1) of the OSI model. It is not an intelligent device because it does not have any memory to store device information. If a computer wants to send information to another computer, the hub broadcasts information to all the other computers, connected to the hub, that’s why it is not an intelligent device. WebThe key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2. Hubs …

WebThis first layer of the OSI model is where physical circuits are made.
