A USB port is a point of connection between a computer and other electronic devices such as tablets, smartphones, pen drives, card readers, printers and scanners. The USB port allows the transfer of data from one device to the other.
The abbreviation USB stands for Universal Serial Bus. It was first developed in the 1990s. Special cables and communication protocols are required for this data transfer to take place through a USB port. Not all USB ports transfer data at the same rate. For instance, a USB 3.0 port transfers data faster than a USB 2.0 port. In addition to standard USB connection types, there are also micro and macro connector types.
