What Is the Difference Between a Switch & a Hub?
Hub Network hubs are the most basic type of network device; they usually have several ports and allow multiple Ethernet clients to talk to one another. Hubs operate at the physical layer of the OSI model and require little or no setup. Connect Ethernet devices to the hub and plug it in. Unfortunately hubs inefficiently handle network transmissions, the basically repeat whatever they hear on one port to every other port. This increases the chances of two devices talking at the same time. When this happens, a collision occurs, slowing down the network. Switch Network switches are more sophisticated than hubs. They intelligently process the network clients they serve. Operating at higher layers of the OSI model, a switch knows where a packet of information came from and where it’s going. So, a conversation between two network clients will not prevent a second conversation between two other network clients. Switches can also operate in full duplex, meaning they simultaneously transmit and
