The Universal Serial Bus (USB) was developed as a standard to define communication protocols between computers and electronic devices. USB refers both to the USB ports and cables with USB connectors.
Universal Serial Bus (USB) 2.0 is a data transfer port released in 2000. It has a max transfer rate of 480 Mbps. It is commonly found on computers and specialized electronics.
USB 3.0 is ten times faster than USB 2.0. This is because there are four smaller connector wires inside a USB 3.0 cable than a USB 2.0 cable that allows for a much higher bandwidth and multiple signals to be exchanged at once.
