3: Tute§park

The Tutespark for week 3 is to find at least three examples of digital devices that are not electronic. Preferably they should be communication technologies.
Before starting the search for digital devices that are not electronic, I have tried to find definitions of the key words in simplistic terms to help me on my quest.

Digital: Information is stored using a series of ones and zeros known as the binary system. Digital devices estimate auditory and visual signals using ones and zeros.

Analog: Information is received in a continuous transmission.

Electronic: Of, implemented on, or controlled by a computer or computer network.

Communication: The technology employed in transmitting messages.

Digital Devices That Are Not Electronic
1. Beacon: perhaps the simplest non-electronic digital signal, with just two states. It's either illuminated, or not.


2. Braille: can be seen as the world's first binary encoding scheme for representing the characters of a writing system.


3. Telegraph: relies on binary code, demonstrating the ease with which binary numbers can be translated into electrical impulses.
