Programming Languages

1. IDE

   • Debugger
     • Allows the end user to enter the program code. It can colour code keywords and may even autocomplete words as you type.
   • Interpreter
     • Translates source code into machine code one line at a time.
   • Compiler
     • Translates the entire source code into machine code.
   • Editor
     • Highlights errors in the code and may suggest possible solutions
   • Stands for Integrated Development Environment and can consist of the following: Debugger, interpreter, compiler, editor. The word DICE can help you remember this!

2. Translator

   • Needed to either compile or interpret the source code so that the computer (CPU) can understand it.

3. High level Programming languages

   • Python
   • Scratch
   • Javascript

4. Low level Programming languages

   • Machine code (binary)
   • Assembler
     • A low level programming language which uses a small instruction set. These instructions are translated into machine code.

5. Mnemonic

   • hortened command words which are used in assembly language. For example, “Little Man Computer” used mnemonics such as “LDA”, “DAT”, “ADD” and “OUT”.

6. Opcode

   • The instruction that the computer (CPU) needs to carry out.

7. operand

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

8. machine code

   • The data or register needed for the instruction.
