1. complier

   • translates all of the source code at the same time and creates one executable file
   • only needed one to create the executable file
   • returns a list of errors for the entire program once compiling is complete
   • once compiled the program runs quickly but compiling can take a long time

2. interpreter

   • translates and runs the source code one instruction at a time, but doesn't create an executable file
   • needed every time and want to run the program
   • the interpreter will return the first error it finds and then stop - this is useful for debugging
   • program will run more slowly because the code is being translated as the program is running

3. high level languages

   • one instruction of high level code represents many instruction of machine code
   • the same code will work for many different machines and processors
   • the programmer can easily store data in lots of different structures without knowing about the memory structure

4. low level languages
