USB...................

通用串行總線
Universal Serial Bus（USB）是連接外部設備的一個串口總線標準，在計算機上使用廣泛，但也可以用在機頂盒和遊戲機上，補充標準On-The-Go（OTG）使其能夠用於在便携設備之間直接交換數據。

USB is the intial of Universal Serial Bus.

It is a serial bus standard to interface devices. A major component in the PC, USB was designed to allow peripherals to be connected using a single "standardized interface socket" and to improve "plug-and-play" capabilities by allowing devices to be connected and disconnected without rebooting the computer.

Other convenient features include providing power to low-consumption devices without the need for an external power supply and allowing many devices to be used without requiring manufacturer specific, individual device drivers to be installed.

手指 is not = USB. 手指 should = portable memory stick But the design of the portable memory stick is usually connected with USB to the computer. So many people simply named it as USB. In fact USB should only refer to the design of the connection pluy but not the memory stick itself.

USB姐係人稱手指既電子零件,可以插落電腦度之後copy番裡面既資料,做個副本(back-up.)

USB 係手機與電腦連接的工具
讓電腦可以讀取手機的資料
