(including whether it is an input or output pin) can be controlled (programmed)

through software. It is a flexible software-controlled digital signal. They are provided

from many kinds of chip, and are familiar to Linux developers working with embedded

and custom hardware. Each GPIO represents a bit connected to a particular pin.

Board schematics show which external hardware connects to which GPIOs. Drivers
