About
A device is any machine or component that can perform an operation.
It is built upon logic gates and therefore only (accept|understand) a series of 0 and 1.
The first device was a transistor.

Interface
The interface of a device is its pins.
The following interfaces are the only software interface:
Writing device drivers is essentially learning the functionality of each register and how to use them properly to control the device.
Example
Chip
The 74HC00 is a chip device composed:
- internally of four 2-input NAND gates
- and externally of 14 pins:
- 8 input pins (red)
- 4 output pins (green)
- 1 pin for connecting to a voltage source (Vcc brown)
- 1 pin for connecting to the ground. (GND brown)
The chip comes with 4 gates that can be combined to create other logic gates (ie logic function)
