A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code.Telegraphy usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that.
Names of many computer terms, especially computer applications, often relate to the function they perform, e.g., a compiler is an application that compiles (programming language source code into the computer's machine language).

Elaborate commercial codes which encoded complete phrases into single words were developed and published as codebooks of thousands of phrases and sentences with corresponding codewords. Commercial codes were not generally intended to keep telegrams private, as codes were widely published; they were usually cost-saving measures only.
In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in that language. This applies both to programming languages, where the document represents source code, and to markup languages, where the document represents data.
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
