ITPEC IP April 2021 Question 8
ITPEC IP April 2021 — Question 8 of 100
Only statement B is correct. A compiler translates source code into lower-level code and, ultimately, machine instructions that the CPU executes. Statement A is false because machine language and assembly language depend on a particular processor instruction set. Statement C is false because any high-level operation must ultimately be expressible as executable machine instructions.
Answer (c)
Why not others:
- options containing A incorrectly claim CPU independence for low-level code
- options containing C incorrectly claim high-level languages can perform calculations impossible in machine language
Key rule: High-level languages improve abstraction and portability, but execution ultimately occurs as CPU-specific machine instructions.
