Computer instructions have exactly defined and limited vocabulary, syntax, and grammar {formal language, programming} {programming language}| {computer language}, with no ambiguities or connotations.
parts
Programming languages have alphabet {character set} that makes numbers and words in formats. They have mathematical functions, logical operations, and string manipulations {operator, programming}. They have processing instructions {executable}. They have sentences {declaration, programming} {non-executable declaration} that name, set up arrays, or create symbols.

Machine uses machine-dependent binary code {machine language}. Assembler uses machine-dependent three-letter codes {assembly language} for instructions and addresses and has one statement for each instruction. People use higher-level languages {compiler language} {high-level language}, with one statement for several instructions, such as BASIC, FORTRAN, COBOL, UNIX, and DOS.
