Compilers, Interpreters, Assemblers & Translators

Keyword Definition
Assembler A program that translates assembly language code into machine code.
Code Generation The process of producing executable machine code or intermediate code from the analyzed source code.
Compiler A program that translates source code written in a high-level programming language into a lower-level language, such as machine code.
Interpreter A program that directly executes instructions written in a high-level programming language without the need for prior translation.
Lexical Analysis The process of breaking down the source code into a sequence of lexemes (tokens) that can be processed by the compiler or interpreter.
Linker A program that combines object code generated by the compiler with external libraries to create an executable program.
Optimization The process of improving the efficiency and performance of the generated machine code.
Semantic Analysis The process of analyzing the meaning of the source code and checking for semantic errors.
Syntax Analysis The process of analyzing the grammar of the source code to determine its syntactic structure.
Translator A program that converts code from one programming language to another without necessarily changing the underlying logic.
