Which term refers to a low-level programming language that uses mnemonic opcodes such as mov, sto, and load to interact directly with a computer's CPU and registers?

• A. Bytecode
• B. Assembly Language
• C. Code
• D. C

Answer: (B)

Working with instructions that map directly to the processor and involve explicit use of registers is assembly language. In this style of programming, each human-readable mnemonic like mov or load stands in for a specific machine instruction, and you control which registers and memory locations are used. An assembler translates these mnemonics into the binary opcodes the CPU can execute, producing code that runs with very little abstraction from the hardware. This direct relationship to the CPU’s instruction set is what defines it as low-level.

Bytecode is intended for a virtual machine and is not executed directly by the processor. C is a high-level language that hides many hardware details from the programmer, even though it can compile down to efficient machine code. So the described term is assembly language.
