Programming Languages

1. IDE

   • Features of an IDE
     • Editor
       • Allows you to write and edit code
         • Auto colour codes key command words
         • Line numbering
     • Error diagnostics
       • Helps find and fix errors in a program by telling the user the location of the error
     • Translator
       • Translates the higher level code into lower level code
         • This allows the computer to execute the instructions as it doesn't recognise high level programming languages
       • Two main types of translator:
         • Interpreter
           • Translates the code line by line until an error is found
         • Compiler
     • Run-time environment
       • Allows the code to be ran within the IDE so that you are able to test your program
   • IDE stands for Integrated Development Environment
   • Examples include IDLE and Pycharm

2. High level programming languages

   • Designed to be understood by humans
   • Examples include Python,Javascript and Scratch

3. Low level programming languages

   • Designed to be understood by computers
   • Examples include binary and assembly language
   • Otherwise known as machine code

4. Assembly language

   • Mnemonics
     • Mnemonics are shortened command words
     • LDA - Load
     • STA - Store
     • ADD - Addition
     • SUB - Subtract
     • DAT - Data
   • Assemblers are used to turn assembly language into machine code
