In machine code, operations need to be specified exactly. For example, if a piece of information needs to be retrieved from memory, the machine code will need to tell the computer where in memory to find it.computer science computer science computer science computer science computer science
Writing directly in machine code is possible, but very difficult.
Low-level programming languages add a bit of abstraction to the machine code. This abstraction hides specific machine code instructions behind declarations that are more human readable. Assembly languages are the lowest-level languages next to machine code.
In machine code, you might write something like “10110000 01100001” — but an assembly language might simplify that to “MOV AL, 61h“. There’s still an almost one-to-one correspondence between what’s written in the assembly language and the instructions passed to the machine.computer science computer science computer science computer science computer science

Moving into more popular programming languages, you’ll come to something like C. While not as low as an assembly language, there’s still a strong correspondence between what’s written in C and the machine code. Most operations written in C can be completed with a small number of machine code instructions.
