A telegraph symbols or code is one way that characters are encoded so that information can be sent by telegraph. Morse code is the one that most people know about. Telegraphy usually refers to the electric telegraph, but the optical telegraph was used before the electric telegraph.
A code is made up of a number of code points, each of which stands for a letter, number, or other character. Codes that are meant for machines, not people, need code points for control characters like carriage return to control how the mechanism works. Each code point is made up of a few parts that are put together in a way that is unique to that character.
In a binary code, there are usually only two types of elements, but some codes that were not made for machines used more types of elements. For example, American Morse code had about five parts, while International Morse code only had two (the dot and the dash).
A telegraph code is one of the ways that telegraphs encode characters. Morse code is the one that most people have heard of.
Invention Of Morse Code
Telegraphy is usually used to talk about the electrical telegraph, but there were also optical telegraph systems in use before the electrical telegraph.
A code is made up of a number of code points, each of which is a letter, an integer, or another character.
Morse code is used in telegraphy, an old way to send messages over long distances. At first, electrical impulses were sent through wires. Later, radio transmissions were used instead.

2. Electrical telegraph codes
3. Automatic telegraph codes
