Chapter 10 - Programming language translators

translates low level assembly language (source code) into machine code (object code that is executable, but is dependent on hardware) or an intermediate, byte code

translates high level languages to machine code; scans source code to build up information to translate to object code (different compilers needed for different hardware) • No need to recompile unless if error is spotted • Runs faster than interpreter • Can be distributed without source code

scans one line at a time and if it contains no syntax errors, executes it Can be run on any computer with appropriate interpreter

• Intermediate between compiling the interpreting • Translated by byte code interpreter • Platform independence – byte code can be translated to any specific machine code • Extra security layer – protects against malicious software
