- One that compiles: a compiler of anthologies.
- Computers A program that translates another program written in a high-level language into machine language so that it can be executed.
compiler - Computer Definition
A computing science term, the compiler transforms human readable source code into binary code that computers understand.
See Also: Code or Source Code.
(1) Software that converts a set of high-level language statements into a lower-level representation. For example, a help compiler converts a text document embedded with appropriate commands into an online help system. A dictionary compiler converts terms and definitions into a dictionary lookup system.
(2) Software that translates a program written in a high-level programming language (C/C++, COBOL, etc.) into machine language. A compiler usually generates assembly language first and then translates the assembly language into machine language. A utility known as a "linker" then combines all required machine language modules into an executable program that can run in the computer. See optimizing compiler. The following is a conceptual example of source code being converted to assembly language and machine code by the compiler: Source Code IF COUNT=10 GOTO END-OF-JOB ELSE GOTO COMPUTE-AGAIN ENDIF Assembly Language Machine Language Compare A to B Compare 3477 2883 If equal go to C If = go to 23732 Go to D Go to 23119 Machine Code 10010101001010001010100 10101010010101001001010 10100101010001010010010
