  • Can an industrial Ethernet switch be used as a hub

    Can an industrial Ethernet switch be used as a hub

    An Ethernet switch serves as a central hub in a network, directing data between connected devices. Network hubs (pictured above) repeat data to its ports, rather than routing data like a switch. Image used courtesy of Moxa While a switch directs the flow of traffic, a hub is simply a repeater. It has no idea where information is going. Unlike the hub, which sends data to all connected devices, an Ethernet switch works more efficiently by recognizing where each packet of information is headed. Ethernet switches essentially serve as central hubs that connect various devices within a network, ensuring that data is effectively transmitted. Hubs forward data packets they receive from a single workstation to ALL ports. It improves network efficiency by reducing congestion and enhancing communication speed. In this article, we'll explore the main differences between Ethernet switches and hubs.
