4 Is Plug and Play, that is when we connect a printer or scanner via the USB interface, is not necessary to shut down the computer so that the new hardware is detected as the system automatically recognizes the connected device and installs the appropriate drivers, which allows it to be Hot Pluggable, it is saying that the user can connect and disconnect USB devices as often as you want without having to turn off and turn on the machine. 5 Is of great benefit for people with less experience in the world of computing, and to connect certain devices such as for example a network or a modem, plate years ago they had to if or if recourse to open the CPU to install the device, all this is much more easy and simple because now these devices are connected externally via USB. 6. USB technology allows connections in operation, so that users can easily incorporate a printer and when they need it, in USB, it is possible to connect up to 127 devices to our computer.
