Sep 18, 2022
1. Can be hot-swappable
This allows users to use external devices without repeating the action of "shutdown, connect the parallel port or serial port cable and then power on", but directly plug in the USB cable when the computer is working.
2. Easy to carry
Most USB devices are known for being "small, light and thin".
3. Standard unification
Before the introduction of the USB interface, the hard disks with the IDE interface, the mouse and keyboard with the serial port, and the printer and scanner with the parallel port were commonly used. With USB hard disk, USB mouse, USB printer and so on.
4. Can connect multiple devices
USB often has multiple interfaces on personal computers, which can connect several devices at the same time. If a USB HUB with four ports is connected, four USB devices can be connected. And so on, connect as much as possible, and connect all the devices in your home to one PC at the same time without any problem (note: up to 127 devices can be connected).
