Programming Languages

1. IDE (Integrated Development Environment) = DICE

   • Debugger
     • Finds Bugs
     • Suggests Fixes
     • Tells you the type of error, which line the error is located even suggestions on how to fix it.
   • Editor
     • Changes the command words colours.
   • Interpreter
     • Translates the source code 1 line at a time.
   • Compiler
     • Translates source code (what youve written) into machine code (Binary)

2. High Level Programming Languages

   • Designed to be understood by humans
     • Python
     • Scratch
     • Javascript
     • HTML

3. Low Level Programming Languages

   • Designed to be understood by computers
     • Assembly Language
       • Shortened command words such as “LDA”, “DAT”, “ADD” and “OUT”.
     • Machine Code (Binary)

4. Mnemonics and Assembly Language

   • Advantages
     • Very easy to write.
     • Easier to understand than machine code.
   • Disadvantages
     • Harder to understand than high level code.

5. ·

   • Opcode
     • The instruction that the computer (CPU) needs to carry out.
   • Operand
     • The data or register needed for the instruction.

6. Translator

   • Translates the entire source code into machine code.

7. Machine Code

   • This is binary code which is designed to be understood by computer systems. It is a low level programming language.
