鼠标英文名称为 Mouse,它是一种移动光标和实现选择操作的计算机输入设备。鼠标于1968年12月9日在美国加州斯坦福大学诞生,它的发明者是 DouglasEnglebart 博士。当时的鼠标是一只小木头盒子,工作原理是由它底部的小球带动枢轴转动,而带动变阻器改变阻值来产生位移信号,信号经计算机处理,屏幕上的光标就可以移动。根据鼠标与电脑主机之间连接的接口方式或类型来分,鼠标接口有串口、PS/2和 USB 三种类型。

The Mouse English name is Mouse, which is a computer input device that moves the cursor and performs selection operations. The mouse was born on December 9, 1968 at Stanford University in California, USA. Its inventor was Dr. Douglas Englebart. At that time, the mouse was a small wooden box. The working principle is that the ball at the bottom of the mouse drives the pivot to rotate, which causes the rheostat to change the resistance to generate a displacement signal. The signal is processed by a computer and the cursor on the screen can be moved. According to the connection between the mouse and the computer host interface or type to points, the mouse interface has a serial port, PS / 2 and USB three types.
