Universal serial bus ( usb ) is new technology about interface in computer application usb has been used widely since the windows operation system supported the usb interface in computer the major goal of usb was to define an external expansion bus which makes adding peripherals to a pc as easy as hooking up a telephone to a wall jack the program ' s driving goals were ease - of - use and low cost these were enabled with an external expansion architecture universal serial bus （ usb ） is one of the most important developments in pc peripheral interconnect technology since the introduction of serial and parallel ports in the early 1980 ' s the benefits of usb ， such as ease of use ， plug and play ， high performance ， and reduced overall system cost ， are just a few of the reasons this technology has gone from specification to product development in less than 2 years
通用串列總線（ usb ）是應用在pc領域中的新型介面技術，自從windons98操作系統全面對usb介面支持后， usb逐漸進入實用階段。利用usb可以實現較傳統方式更有效、更經濟、更多擴展的pc外設與pc相連。通用串列總線（ usb ）作為一種新興的計算機外設總線標準，從標準的出現到大規模的應用，僅用了短短幾年的時間，這一切都得益於它易用、真正的熱插拔、高性能和系統造價低廉等憂點。 -
