Two types of input

1. User input: When a user interacts with a software application, they may provide input through a keyboard, mouse, touch screen, microphone, or other input devices. This input can include text, numbers, commands, or other data that the program can process and respond to.

2. Sensor input: Many digital tools and devices, such as smartphones, smartwatches, and IoT (Internet of Things) devices, can receive input from sensors. These sensors can detect various environmental conditions, such as temperature, light levels, motion, proximity, and more, and provide this data as input for the device to use in its operations.
