Programming Languages

Programming Languages

1. IDE (Integrated Development Environment)

   • Tree
     • Translator
       • Interpreter
         • Translates and runs the source code one instruction at a time but doesn't create an executable file
       • Assembler
         • Assemblers are used to turn assembly language into machine code.
         • There are many different assembly languages to support different CPU types and each one needs its own unique assembler.
       • Compiler
         • Translates all of the source code at the same time and creates one executable file.
       • Translates source code into machine code.
     • Run Time Environment
       • Allows you to test your code quickly so you can test your code to see if it works.
     • Editor
       • Editor allows you to write and edit your code.
     • Error Diagnostics
       • Used to debug your code. It locates errors and suggests ways in which to fix it.

2. High level languages

   • One instruction of high level code represent many instructions of machine code.

3. Low level languages

   • One instruction of assembly code usually only represents one instruction of machine code.
   • machine code
     • Code designed to be understood by the computer like binary.
   • mnemonics
