Explanation
|
|
| USB master (A-type) |
USB slave (B-type) |
USB is a user friendly I/O-interface for connecting peripherals to your PC.
A distinction is made between
- USB 1.1 (transfer rate 12 mbit/sec)
- USB 2.0 (transfer rate 480 mbit/sec)
USB 2.0 devices are backward compatible (with slower transfer rate) with USB 1.1 devices.
An USB connection consists of a shielded cable and two unequal plugs: One for the master (A-type) and one for the client port (B-type).
On phones USB master ports are used to connect additional devices like keyboard or USB memory stick. USB slave ports are used to establish a connection to a PC to use First Party CTI.

Der USB ist eine anwenderfreundliche I/O-Schnittstelle zum Anschluss diverser Peripheriegeräte an einen PC.
Man unterscheidet zwischen
- USB 1.1 (Übertragsrate 12 mbit/sec)
- USB 2.0 (Übertragsrate 480 mbit/sec)
USB 2.0-Geräte sind, mit langsamerer Übertragungsgeschwindigkeit, normalerweise abwärtskompatibel zu USB 1.1-Geräten.
