computing languages - Coggle Diagram

- - - - hard to find errors
      - have to wait until the whole program is perfect to run
    - - High level language commands are like a predefined English sentence and machine code instructions are like predefined words.
      - they can build their own complex sentences or keep programs very short and simple.
      - doesn't need translating
      - quick to run
- - - - If the programmer wants a program to do something, but a statement does not exist to do so, the task cannot be done.
      - they are restricted to the number of statements built into them
    - - They allow the programmer to focus on what needs to be done, rather than on how the computer actually works.
      - Programmers write in high-level languages because they are easier to understand and are less complex than machine code.
- - - - Additionally, the program has to be translated every time it is run
      - Interpreted programs run slowly as the processor has to wait for each instruction to be translated before it can be executed.
    - - Errors can be quickly spotted - once an error is found, the program stops running and the user is notified at which part of the program the interpretation has failed.
      - Instructions are executed as soon as they are translated.
- - - - Source code compiled on one platform will not run on another - the machine code is specific to the processor's architecture.
      - The source code must be re-compiled every time the programmer changes the program.
    - - Compilers optimise code. Optimised code can run quicker and take up less memory space.
      - Compiled programs run quickly, since they have already been translated.
