1. IDE

   • IDE stands for Integrated Development Environment
   • Features of an IDE
     • TREE
       • Editor
         • Auto colour codes key command words, edit your code, auto indents when a colon is entered
       • Error diagnostics
         • Helps you debug your code by spotting errors when you run the code it might also tell you the line the errors on
       • Run-time environment
         • A place where you can run and test your code quickly because you don't need to compile your code into an executable
       • Translator
         • Turns high level code into low level code so it's easier to understand
           • interpreter
             • It translates the code one line at a time until it finds a error in the code. Doesn't create a executable file.
           • Compiler
             • It translates the entire code at the same time and creates one executable file. Returns a list of errors if there are any
   • Examples include IDLE and Pycharm

2. High level programming languages

   • Designed to be understood by humans
   • Python, Scratch, Java Script

3. Low level programming languages

   • Designed to be understood by CPU
   • Java, C++, Pascal

4. Assembly Language

   • A low level code converted by the assembler

5. Assembler

   • a program that converts low level instructions into machine code.

6. Mnemonics

   • They're shortened Command words E.g load = LDA, store= STA
