""Topic: Coding""

The illustration provided shows railroad semaphores. This is a fantastic choice for illustrating "coding" because it illuminates the following facts:

1. coding does not necessarily refer to programs that are compiled or interpreted. the word can also be used to mean that messages can be transmitted using symbols. Railroad semaphores and other kinds of semaphores, in our distant past, served the purposes that we ascribe to telecommunications today. Smoke signals also deserve to be included as a coding technique.

The establishment of standard symbols and meanings is a communication protocol, which is comparable to the Internet, TCP/IP and other data network protocols.

While no longer in common use, semaphores serve a very poignant purpose in explaining the depth of the subject and its relationship to our shared history and destiny.

Semaphores also signify the clever technique invented by Dr. Edgar Djikstra who was able to offer a complete solution to concurrent access to shared data or shared resources. BRAVO TO THE GLASS PLATE GAME for creating such a comprehensively meaningful way to express quintessential matters of our existence.
