摘   要
USB是英文Universal Serial Bus的縮寫，中文含義是“通用串行總線”。它是一種應用在PC領域的新型接口技術。早在1995年，就已經有PC機帶有USB接口了，但由于缺乏軟件及硬件設備的支持，這些PC機的USB接口都閑置未用。1998年后，隨著微軟在Windows 98中內置了對USB接口的支持模塊，加上USB設備的日漸增多，USB接口才逐步走進了實用階段。
這幾年，隨著大量支持USB的個人電腦的普及，USB逐步成為PC機的標準接口已經是大勢所趨。在主機(host)端，最新推出的PC機幾乎100%支持USB；而在外設(device)端，使用USB接口的設備也與日俱增，例如數碼相機、掃描儀、游戲桿、磁帶和軟驅、圖像設備、打印機、鍵盤、鼠標等等

Abstract
English USB Universal Serial Bus acronym, Chinese meaning is 'Universal Serial Bus.' It is a PC application in the field of new interface technologies. As early as 1995, there was already a PC with a USB interface. However, the lack of software and hardware support, PC USB interface were inactive. After 1998, with the Microsoft Windows 98 built-in USB interface for the support module, USB devices with the increasing number of USB gradually entered the practical stage. In recent years, with substantial support USB PC penetration. USB PC gradually become the standard interface is the general trend. The host (host) side, the newly introduced PC - almost 100% support Apple In Peripherals (device) end, the use of USB interface equipment is growing, such as digital cameras, scanners, joysticks, tapes and floppy
