A computer peripheral device is a hardware component that is connected to a computer system to add functionality and enhance its capabilities. It is an auxiliary device that works in conjunction with the central processing unit (CPU) to provide input, output, and storage capabilities.
Peripheral devices can be classified into various categories based on their functions. Input devices are used to send data and instructions to the computer. Examples of input devices include keyboards, mice, scanners, and digital cameras. Output devices are used to display or present the processed information from the computer. Common examples of output devices include monitors, printers, and speakers.
Storage devices are used for storing data and software programs. They provide a means to save and retrieve information, such as hard disk drives, floppy disks, and USB flash drives. Other types of peripheral devices include networking devices like routers and modems, which facilitate communication between computers in a network.
These devices are connected to the computer through various interfaces such as USB (Universal Serial Bus), HDMI (High-Definition Multimedia Interface), or Bluetooth. They are typically plug-and-play devices, meaning they can be easily connected or disconnected from the computer without requiring any complex setup processes.
In summary, a computer peripheral device is an external hardware component that extends the functionality of a computer system by enabling input, output, storage, and communication capabilities.
