An Overview of USB Hubs
A USB hub is a device with multiple USB ports and connects to a computer USB port to increase the number of USB ports available. USB hubs save you from the constant struggle of plugging and unplugging USB devices if you have a shortage of USB ports. Other than increasing the number of USB ports the other common uses of USB hubs include;
- Provide a powering mechanism to USB devices
- Allows simultaneous access and use of multiple USB devices
- Allows convenient usage of shared devices such as printers
USB hubs can effectively connect multiple devices to a peripheral especially when sharing peripherals such as scanners and printers. This eliminates the need to move the peripheral device regularly from one computer or place to another.
