Peripheral Control
Peripheral control is a method of communication between the central processing unit (CPU) and peripheral devices. Peripheral devices include input devices (such as keyboards, mice, and sensors), output devices (such as displays, speakers, and lights), and devices that require control signals or data transfers.
How it works:
Data is read from peripheral devices: When a peripheral device generates data, it sends it to the CPU through a data line.
CPU requests data: The CPU identifies the peripheral device responsible for the data.
Data transfer: The CPU sends the requested data to the peripheral device through the data lines.
Data is displayed or acted upon: The peripheral device receives the data and performs the necessary operations, such as displaying it on a display or playing a sound.
Examples:
Input: When you press a key on a keyboard, the peripheral device sends the data (the key press) to the CPU.
Output: When a printer finishes printing a document, it sends the data (the printed content) to the CPU.
Control: A device like a mouse allows you to control the computer's cursor movement and selection
