Feedback
1. A low-level programming language is a programming language that provides little or no abstraction from a computer’s instruction set architecture—commands or functions in the language map closely to processor instructions. it refers to either machine code or assembly language. while high-level programming languages are those closer to human languages and further from machine languages.
2. Very hard to read or learn for the uninitiated.
- Not very self-documenting like higher level languages.
- Harder to modify and maintain.
- Less support, than high level languages, in development and debug environments.
3. Is a set of instructions executed directly by a computer’s central processing unit (CPU). Each instruction performs a very specific task, such as a load, a jump, or an Arithmetic logic unit (ALU) operation on a unit of data in a CPU register or memory.
