Hubs and switches are both networking devices used to connect multiple devices in a Local Area Network (LAN). However, they differ significantly in terms of network functionality and data processing capabilities. Hubs operate at the physical layer (Layer 1) of the OSI model. They are essentially multi-port repeaters, which means they broadcast data packets to

Single core fiber optic cables can indeed operate in half duplex mode but not in full duplex mode. This limitation is due to the physical properties of the fiber optic medium itself. To understand why this is the case, it is important to delve into the concepts of half duplex and full duplex communication modes,
