What does a mouse belong to in a computer?

In computers, the mouse is an input device; an input device is a device that inputs data and information to the computer, and is a bridge for communication between the computer and the user or other devices. Input devices are also one of the main devices for information exchange between users and computer systems; keyboards, mice, cameras, scanners, light pens, voice input devices, etc. are all input devices.

#The operating environment of this article: Windows 7 system, Dell G3 computer.

The mouse is an input device in the computer.

Currently commonly used input devices include keyboards, mice, scanners, etc.

Input device: A device that inputs data and information to the computer. It is a bridge between computers and users or other devices. Input devices are one of the main devices for information exchange between users and computer systems. Keyboards, mice, cameras, scanners, light pens, handwriting input tablets, joysticks, voice input devices, etc. are all input devices. Input device (InputDevice) is a device for human or external interaction with the computer. It is used to input raw data and programs for processing these numbers into the computer. Computers can receive a variety of data, which can be numerical data or various non-numeric data, such as graphics, images, sounds, etc., which can be input into the computer through different types of input devices for processing. Storage, processing and output.

The symmetry of "output device" is a device that inputs data and information to the computer. It is a bridge between computers and users or other devices. Input devices are one of the main devices for information exchange between users and computer systems. Keyboards, mice, cameras, scanners, light pens, handwriting input pads, joysticks, voice input devices, etc. all belong to input devices. It is a device for humans or external devices to interact with computers, and is used to input raw data and programs for processing these data into the computer. A device that converts input information into a data form that can be processed by a computer. The information input by the computer comes in the form of numbers, analog quantities, text symbols, voices, graphics and images. For these information forms, computers often cannot process them directly. They must be converted into corresponding digital codes before they can be processed. The transfer rates of input information also vary greatly, and they do not match the rate at which the computer works. One function of input devices is to coordinate these two aspects and improve computer work efficiency. There are many types of input devices. In addition to text and digital input devices, input devices for analog signals include digital-to-analog and analog-to-digital conversion devices; input devices for graphics and images include mode information input and output devices; data preparation for offline input information The device has data preparation equipment, etc.

Today’s computers can receive a variety of data, which can be numerical data or various non-numeric data, such as graphics, images, sounds, etc., which can be processed through different types of data. Input devices provide input to the computer for storage, processing, and output.

Computer input devices can be divided into the following categories according to their functions:

Character input device: keyboard;

Optical reading device: optical mark reader, optical character reader ;

Graphic input devices: mouse, joystick, light pen;

Image input devices: cameras, scanners, fax machines;

Analog input devices: language analog-to-digital conversion recognition system. Output device:

Outputs data or information from the computer to the user. Output device (OutputDevice) is a component for interaction between humans and computers, used for data output. It expresses various calculation result data or information in the form of numbers, characters, images, sounds, etc. Common ones include monitors, printers, plotters, image output systems, voice output systems, magnetic recording equipment, etc.

is both an input device and an output device: storage devices include internal memory and external memory. Floppy disks, hard disks, optical disks, U disks, mobile hard disks, etc. are external memories. Internal memory is divided into RAM and ROM. RAM is Random access memory, ROM is read-only memory, and the memory stick is RAM. ROM refers to the chip on the motherboard that stores the BIOS.
