2.5 translators

1. language translators

   • used to translate language into a form that can be directly executed
   • examples include
     • compiler
     • interpreter
     • assembler

2. high level language

   • aka source code
   • advantages
     • close to English language
     • aimed at humans
     • programming language using English like language an mathematic symbols
     • code is portable
       • can be used on any computer
   • has to be translated using a compiler or interpreter

3. compiler

   • doesn't reveal source code
   • faster
   • program that translates a program written in a high level language to the machine language of a computer
   • entire source code has to be completed when complied
   • turns source code into machine code
     • inputs are processed when program is running

4. IDE

   • Integrated Development Environment
   • Error diagnostics
   • Runs Time Environment
   • Translators
   • Debugging

5. Interpreter

   • more flexible
   • translates line by line
   • interprets inputs at the same time as source code
   • An analogy would be interpreting a speech line by line

6. low level language

   • machine language
     • no need for translators
     • 1st generation
     • written in the language of the computer
   • assembly language
     • 2nd generation
     • translated by an assembler
