High level

• Closer to the semantics of spoken language
• Each line of high level language translates in to multiple lines of machine code
• Identifiers can be long and meaningful
• Modules can be re-used throughout the program

Low level

<aside> 🏗️ i.e. assembly code

</aside>

• Reflect the design of the processor on which they are to run much more closely than their high-level equivalent
• Use mnemonics (assembly)
• Each line of low level language is translate into one machine code instruction
• Developer can manipulate the memory registers and CPU
• Much more efficient than high level, as translates to machine code much quicker
