不能給使用添堵!談?wù)劰P記本接口的重要性

在眾多有線(xiàn)接口當中，最常用的當屬USB接口了。USB是英文Universal Serial BUS(通用串行總線(xiàn))的縮寫(xiě)，USB接口是目前筆記本上最常用的接口之一，因為大多外接設備，如U盤(pán)、移動(dòng)硬盤(pán)、鼠標、手機等，都是通過(guò)USB接口和筆記本電腦連接的。

USB接口具有四大特點(diǎn)：1、USB設備大多可以可以熱插拔，在P電腦開(kāi)機時(shí)就可以將USB電纜插上使用;2、USB設備大多攜帶方便，以“小、輕、薄”設備為主，是最方便的數據交換途徑;3、USB接口標準統一、應用廣泛，移動(dòng)硬盤(pán)、鼠標、打印機等都可通用連接USB;4、可以連接多個(gè)設備。USB在PC上往往具有多個(gè)接口，可以同時(shí)連接幾個(gè)設備，如果外接一個(gè)USB HUB，那么能連接的設備就更多了。
