What is Low Level Language ?

What is machine Level Language ?

  1. Machine code is the only language a microprocessor can process directly without a previous transformation.
  2. Currently, Programmers never write programs directly in machine code, because it requires attention to numerous details which a high-level language would handle automatically.
  3. Low Level Language requires memorizing or looking up numerical codes for every instruction that is used.
  4. For this reason, second generation programming languages provide one abstraction level on top of the machine code.
