To be clear from the outset, it is actually the memory management work that takes up bulk of the work in assembly programming, not the instruction sequences themselves, which can be taken as enablers or the core vocabulary. Each instruction sequence is atomic, and like a set of symbols that have a singular meaning and purpose, very linear. Each instruction in the text form above is called a mnemonic, where each assembly instruction can be taken as a function with a certain requirement and output.
Each assembly line is directly mapped to an opcode sequence consisting of byte patterns that are unique to a particular architecture, for our purposes, the 80x86 family of Intel microprocessors. This mapping is done by an assembler (having dual meaning of both the language and the software used to generate the machine object code), which creates object code from assembly text, which is then processed by the linker to get the final executable.
