A peripheral is a device that is connected to a computer but is not part of the essential components of the computer, such as the central processing unit, memory, or storage. The most common type of peripheral is an input/output (I/O) device, which sends information to, or receives information from, the computer.
Common examples of peripherals include keyboards, mice, printers, scanners, and digital cameras. Some peripherals, such as external hard drives and flash drives, are used for storage purposes. Others, such as modems and network adapters, are used to connect the computer to other devices or networks.
Types of Peripheral Devices :
There are two types of peripheral devices that can be attached to a computer: input devices and output devices. Input devices allow users to enter information into the computer, while output devices provide a way for the computer to communicate information to the user. Common input devices include keyboards, mice, and scanners. Output devices include monitors, printers, and speakers.

Uses of Peripheral Devices :
Peripheral devices are those devices that are external to the computer, and are used to enhance the functionality of the computer. Some of the most common peripheral devices include the following:
1. Storage devices: These devices are used to store data and information. Some of the most common storage devices include hard drives, solid state drives, and optical drives.
2. Input devices: These devices are used to input data and information into the computer. Some of the most common input devices include keyboards, mice, and touchpads.
3. Output devices: These devices are used to output data and information from the computer. Some of the most common output devices include monitors, printers, and speakers.
Conclusion :
Peripheral devices are devices that are attached to a computer in order to extend its capabilities. These devices can be external, like a printer or scanner, or internal, like a sound card or video card. Without peripheral devices, a computer would be much less functional and would not be able to perform many common tasks.
