Programming languages.

Programming languages.

1. Low level (machine code) programming languages.

   • Designed to be under stood by computers.
   • Examples:Binary, assembly language & Little man computer.
   • shortened command words are used in assembely language an example would be little man computer.
   • It is binary code which is designed to be understood by computer systems.

2. High level programming languages.

   • IDE.
     • Editor.
       • Write/edit code and colour code keywords.
     • Debugger.
       • Identifies errors in your code and can highlight the location of the error .
     • Interpreter.
       • Allows you to translate source code line by line when testing your code.
     • Compiler.
       • converts the source code into machine code so that it can be exacuted as a stand alone program file.
     • Stands for Integrated Development Environment.
   • Under stood by humans.
   • Examples:Python, Scratch & Javascript.

3. Operand.

   • a term used to describe any object that is capable of being manipulated. For example, in "1 + 2" the "1" and "2" are the operands and the "+" is the operator.

4. opcode

   • It is the portion of a machine language instruction that specifies the operation to be performed.

5. Mnemonic

   • Mnemonic is shortend command words like LDA to be better understood by humans than machine code but not as understandable as high level coding.
