What Is USB Splitter

USB splitter is a hardware device that splits one USB port into two or more USB lines. It increases the number of devices that can be connected to one USB port, which allows multiple external devices to run in parallel on the same computer simultaneously. 

With USB splitter, you can attach the USB end to your computer's USB interface and then connect other peripheral ports to external devices like mice, keyboards, printers, scanners, USB hard drivers, etc. 

Another distinguishing feature of a USB splitter is to prevent your PC's overload, ensuring a smooth performance.

What Is USB Hub

USB hub, also known as USB port hub and multiple adapter. Unlike the splitter, the USB hub looks like a mini power strip. One end is the USB interface for connecting to the computer host, the other is the HUB, and the port is expanded into multiple ports. All devices share the bandwidth available to that hub. It allows interaction with multiple USB devices simultaneously, such as mice, keyboards, printers, USB drives, and portable storage drives. In addition to USB ports, a hub can have ports like USB to HDMI adapter, to Ethernet, or mini USB for a wired internet connection and better screen display effect.
