或许你只是一位计算机的使用者,对于计算机的硬件知识懂得很少。那么你是否会在安装你的计算机的鼠标、键盘、打印机等等外设的时候为复杂的安装过程而烦恼?你是否为安装外设时为合理的配置系统的资源而大伤脑筋呢?现在,已经有了一种新的输入/输出接口标准——USB问世了。有了它,您就再也不会为这些事而犯愁了。 随着Windows 98操作系统的推出,USB的软件系统支持得到了解决,使得我们可以在PC上使用USB端口了。那么,什么是USB,USB有那些特点,如何使用USB呢?这些都成为我们在选择使用USB之前必须了解的问题了。USB是“Universal Serial Bus”的缩写,意思是“通用串行总线”,但要注意的是它并不是一种新的总线标准,而是电脑系统连接外围设备(如键盘、鼠标、打印机等)的一种输入/输出标准。由于现在电脑系统的外围接口没有统一的标准,例如键盘插口为圆形的、连接打印机的则为9针或25针的并行接口、而鼠标用的则是9针或25针的串行接口,从而给外
Perhaps you are just a computer user, little knowledge of the computer hardware. Would you be annoyed by the complex installation process when installing your computer’s mouse, keyboard, printer, and other peripherals? Are you bothering with the proper configuration of system resources when installing peripherals? Now , There is already a new input / output interface standard - USB came out. With it, you no longer have to worry about these things. With the introduction of the Windows 98 operating system, USB’s software system support has been fixed, allowing us to use USB ports on our PCs. So, what are USB, USB have those characteristics, how to use USB? These have become we have to understand before choosing to use USB. USB is an abbreviation for “Universal Serial Bus,” meaning “universal serial bus,” but beware that it is not a new bus standard. Instead, a computer system connects peripherals (such as keyboards, mice, printers, etc.) An input / output standard. As the computer peripheral interface is not uniform standards, such as the keyboard socket is circular, connected to the printer is a 9-pin or 25-pin parallel interface, while the mouse is used 9-pin or 25-pin serial interface, To the outside
