Compiler, Interpreter and Assembler Comparison

Translators comparison diagram showing three translation methods: Compiler takes entire high-level source code and produces a standalone executable file (translated all at once, fast execution), Interpreter takes high-level source code and executes it directly line by line (no output file, slower execution, stops at first error), and Assembler converts assembly language mnemonics to machine code in a near one-to-one translation, with examples of when each is used
