Assembly language
- [Instructor] We have talked about the instruction set which composes the program a CPU will execute in what is known as machine language. However, when programmers deal with low-level code, they use assembly language. Assembly language is an abstraction layer directly above machine language, providing a more human-readable way to write instructions that the CPU understands. Instead of working with binary values to encode operations and operants, assembly language uses mnemonics to represent each instruction, making code easier to understand and write. Each assembly instruction directly corresponds to a single machine instruction, keeping it close to how the CPU processes tasks. Now, since assembly code is a higher abstraction than machine code, there is a special program called an assembler, which converts a text file containing a program in this human-friendly assembly language into its machine language equivalent in a binary file. This file is eventually sent to the processor's…
