USB ports are ubiquitous, with many newer motherboards offering up to 10 USB connections. USB is available in two common versions-version 1.1, which has a maximum data transfer rate of 12 Megabits per second, and version 2, which tops out at 480 Megabits per second.

Besides speed, USB also allows up to IJ6 compatible devices to be connected in a daisy~hain into a single port, and it also supports hot-swapping (the system would detect the newly onnected device without requiring a restart).
