This article mainly introduces what is the most commonly used type of mouse interface in the computer, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

At present, the most commonly used mouse interface type is USB interface. USB is the abbreviation of "Univer Serial Bus" in English, which means "Universal Serial bus" in Chinese. The most transmission rate of big data is 12Mbps and 480Mbps, which is a kind of high-speed general interface.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

USB is the abbreviation of Univer Serial Bus in English, which means Universal Serial bus in Chinese. The common USB interfaces before 2013 can be divided into USB1.1 and USB2.0 according to their versions, and their highest big data transmission rates are 12Mbps and 480Mbps respectively, which is a high-speed general-purpose interface. This is a new type of mouse interface, many new mouse products before 2013 have adopted the USB interface, compared with the first two interfaces, its advantage is a very high data transfer rate, can fully meet a variety of mouse refresh rate and resolution requirements, can make a variety of high-grade mouse to give full play to its performance, and support hot plug. And with the popularity of the BTX specification, this will be the only mouse interface in the future.

Extended data:

There are three types of mouse interface: serial port, PS/2 and USB.

Serial port is the serial interface, that is, COM interface. This is the oldest mouse interface, a 9-pin or 25-pin D-type interface that can be used when the mouse is connected to the serial port of the host computer. Its advantage is that the scope of application and models are the most, from the ancient computers without PS/2 interface and USB interface to the latest computers, but the disadvantage is that the data transfer rate of serial communication is too low, the medium and high-grade mouse can not play its high performance advantages, and does not support hot plug. Serial port has been cancelled in the latest BTX motherboard specification. With the popularity of BTX specification, serial port mouse has been very rare.

PS/2 interface is a mouse interface introduced by IBM Company in 1987, commonly known as "small mouth". This is a special interface for mouse and keyboard, and it is a 6-pin round interface. However, the mouse only uses four of these pins to transmit data and power supply, and the other two are empty feet. The transmission rate of the PS/2 interface is slightly faster than that of the COM interface, and it is the standard interface of the ATX motherboard. Although the PS/2 interface has been widely used, it does not support hot plug and can not make the high-grade mouse give full play to its performance. Now it has been basically replaced by the USB interface. This is also the interface that is about to be eliminated in the BTX motherboard specification.
