What does machine code look like and how is it different from high-level programming languages?

Machine code is a low-level programming language that consists of binary code that can be directly executed by a computer's central processing unit (CPU). It is made up of sequences of 0s and 1s that represent specific instructions for the CPU to carry out. Machine code is specific to the hardware architecture of a computer and is difficult for humans to read and write.

On the other hand, high-level programming languages are designed to be easier for humans to understand and write. They use more human-readable syntax and are closer to natural language. High-level languages need to be translated into machine code before they can be executed by a computer, usually through the use of a compiler or interpreter. This translation process allows high-level languages to be more portable across different hardware platforms compared to machine code.
