Peripheral
A peripheral is any external device that connects to a computer to expand its capabilities, such as input, output, or storage. Examples include keyboards and mice (input), printers and monitors (output), and external hard drives (storage). These devices are not essential for a computer to function but enhance its use.
Connection types
Wired: Connected via a physical cable, such as USB or HDMI. These connections are typically reliable and secure.
Wireless: Use connections like Bluetooth or Wi-Fi for convenience and flexibility, though they can be less secure and more susceptible to interference.
