A peripheral is an external device connected to a computer that adds functionality or enhances its capabilities. Peripherals are not part of the core computer system (CPU, memory, or motherboard) but allow users to interact with the computer or extend its features.
Common examples of peripherals include keyboards, mice, printers, scanners, monitors, external hard drives, webcams, and speakers. They can be input devices (like keyboards and mice), output devices (like printers and monitors), or storage devices (like external hard drives and USB flash drives).
Peripherals connect to computers through various ports and interfaces such as USB, HDMI, Bluetooth, or Ethernet. They are widely used in offices, schools, homes, and data centers to improve productivity, communication, and entertainment.
Modern peripherals often support plug-and-play functionality, meaning they can work immediately after being connected without installing additional software. Understanding peripherals is essential for setting up, troubleshooting, and upgrading computer systems.
