What's the difference between a mechanical mouse and an ordinary mouse?

According to the principle, the mouse can be divided into mechanical mouse and photoelectric mouse.

Advantages and disadvantages of photoelectric mouse compared with mechanical mouse;

Mechanical mouse, also known as roller mouse, is mainly composed of roller ball, roller column and grating signal sensor. The mouse is connected to the host through ps/2 port or serial port. The photoelectric mouse completely gets rid of the ball mechanical structure of the mechanical mouse and is replaced by a high-precision optical sensor, thus getting rid of the shackles of the mouse pad and can be used on various surfaces.

Without the wheel of the mechanical mouse, the photoelectric mouse will generally not roll the dirt on the desktop into the mouse when it is used, so that the mouse is no longer a place to shelter evil people and shelter evil practices. The closed structure of the photoelectric mouse makes the mouse still sensitive and smooth after long-term use, and the life of the mouse is greatly prolonged.

Mouse is the input device of computer, which can be divided into wired and wireless, and it is also the indicator of vertical and horizontal coordinate positioning of computer display system. It is named "mouse" because it looks like a mouse.

The standard name of "Mouse" should be "mouse" and the English name is "mouse". The use of the mouse is to make the operation of the computer simpler and faster, instead of the tedious instructions of the keyboard.

The mouse is Douglas's 1964? Engelbarth invented it. At that time, DouglasEngelbart worked at Stanford Research Institute (SRI), an institution sponsored by Stanford University. DouglasEngelbart has long been thinking about how to make the operation of the computer easier and what means to replace the tedious instructions entered by the keyboard.
