Covers high level programming languages and low level programming languages, plus the difference between compilers and interpreters, for Edexcel topic 4.5 but also useful for other exam boards.

A clear explanation of the differences between the many programming languages available. Near the beginning of the video is an excellent diagram that shows machine code, low level languages, high level languages, and human languages on the same continuum, to help you understand how they differ. It then goes into more detail about the benefits and drawbacks of each language type.

A good follow up to this video is Translators (Assembler, Compiler & Interpreter), created by the same person.

The CS Field Guide has a very comprehensive guide to different types of programming languages. These range from very high level graphical languages such as Scratch, down to assembly language and machine code. The differences between each language type are clearly explained. There are also lots of interactive elements to try, including a MIPS assembler and simulator to allow students to try assembly language without risk of damage to their machine.

The relationships between translators, compilers, and interpreters confuses many students. Throw in assemblers and it can be hard to understand anything about this topic. This video tries to address that confusion, with clear explanations and lots of clear examples.

I'd recommend watching the video Machine, Assembly & High-Level Programming Languages (from the same creator) first, particularly if you're unclear about the difference between assembly language and higher level languages like Python.
