1) General Purpose Inner Outer Propeller
2) General Purpose Interested Old People
3) General Purpose Input Output Pins
4) General Purpose Input Output Processor

Answer 1

GPIO stands for General Purpose Input Output Pins, which are versatile pins on a microcontroller or similar device that can be set as input or output for interfacing hardware with software.

Step-by-step explanation:

GPIO stands for General Purpose Input Output Pins. These are physical pins on a circuit board like a microcontroller or a Raspberry Pi that can be programmed to function as either an input or an output. For example, you can use a GPIO pin as an input to read the state of a button or as an output to control an LED light. GPIO pins are essential for interfacing hardware with software. When a pin is set as an input, it can be used to read values from sensors, such as temperature or light, while pins set as outputs can be used to drive actuators like motors, lights, or even other circuits. This functionality makes GPIO pins very versatile and important in computer and electronics projects
