A mobile phone and a desktop computer are two examples of devices that may be linked together using the USB standard. A cable with connectors on either end makes the connection. All USB cables have the same one end that goes into the computer, while the other end that plugs into the mobile device might have a proprietary connection, microUSB, miniUSB, or another variety.
The present USB version 2.0 is about 40 times faster than USB version 1.1, which has a maximum speed of 1.5 MB/s. The slower gadget limits the speed, and the versions are backwards compatible. Drivers may need to be installed on the desktop computer in order to transfer data, however certain phones include “mass storage” mode, which allows the phone to connect to the computer like a thumb drive without the need for additional drivers.
Several mobile phones can be charged via their USB connection, and USB cables not only convey data but also carry an electric charge that may be used to power accessories like USB mice and keyboards.
