大家都知道,PC中每个设备都有它自己的一套连接的接口。但是,随着现在外设逐渐的增多,外设接口的规格不一,有限的接口数量,已经无法满足众多外设连接的迫切需要。惟一能解决这个问题的方法就是提供一个设备的共享接口来解决个人计算机与周边设备的通用连接。随之而来的,就是USB技术的诞生。USB技术可以说是计算机外设连接技术的重大变革。现在,随着众多设备比如键盘、鼠标、游戏杆、扫描仪、显示器、数字相机以及MODEM等对USB接口的支持,USB接口也变得越来越重要起来。那么,什么是
Everyone knows that every device in a PC has its own set of connected interfaces. However, with the gradual increase in peripherals nowadays, peripheral interfaces have different specifications and the limited number of interfaces can not meet the urgent needs of many peripherals. The only way to solve this problem is to provide a device’s shared interface to solve the common connection between personal computers and peripherals. Followed, is the birth of USB technology. USB technology can be said that the computer peripheral connection technology major changes. USB interfaces are also becoming more and more important nowadays with the support of USB devices such as keyboards, mice, joysticks, scanners, monitors, digital cameras, and MODEMs. So what is it?
