Programming Language

Programming Language

1. IDE - (Integrated Development Environment)

   • Debugger
     • Highlight errors in the code.
     • Suggests possible solutions
   • Interpreter
     • A translator that turns the source code into machine code one line at a time and runs it one instruction at a time.
   • Complier
     • A programming tool to translate source code into machine code.
   • Editor
     • Allows the end user to enter the program code. It can be colour code keywords and may even autocomplete words as you type.

2. Translator

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

3. Assembler

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

4. Mnemonic

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

5. Opcode

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

6. Operand

   • The data or register needed for the instruction.

7. Low level programming language

   • Instructions use binary code or mnemonics.
   • A programming language designed to be understood by computers. For example, machine code (binary).
   • It's specific to a particular machine (computer)

8. High level programming language

   • Instructions are coded using words.
   • A programming language designed to be understood by humans (e.g. Python, Scratch and JavaScript).
   • It's portable and can be used on other machines (computers).
