The hub will create four ports out of one, giving you five total ports. For example, if your computer has two USB ports, but you want to connect five USB devices, you can connect a 4-port USB hub to one of the ports. It is designed to increase the number of USB devices you can connect to a computer. USB hubĪ USB hub is a device that allows multiple peripherals to connect through a single USB port. For this reason, switches are much more commonly used than hubs. While this ensures the data gets to the right port, it also leads to inefficient use of the network bandwidth. For example, if five devices are connected to an 8-port hub, all data received by the hub is relayed to the five active ports. Hubs are similar to switches, but are not as "smart." While switches send incoming data to a specific port, hubs broadcast all incoming data to all active ports. Each computer or device connected to the hub can communicate with any other device connected to one of the hub's Ethernet ports. It has several Ethernet ports that are used to connect two or more network devices together. Network hubĪ network hub is a device that allows multiple computers to communicate with each other over a network. There are two primary types of hubs in the computing world: 1) network hubs and 2) USB hubs.
