ITPEC IP October 2021 Question 11
ITPEC IP October 2021 — Question 11 of 100
A compatible CPU can execute the operating system and application software that ran on the original CPU. Compatibility means preserving the relevant instruction set and software-visible behavior, even if the new processor has a different internal design or higher performance.
Answer (a)
Why not others:
- identical clock speed does not guarantee that the same instructions can run
- using the same physical socket alone does not establish software compatibility
- equal power consumption is unrelated to whether programs can execute
Key rule: CPU compatibility is determined by the software interface, especially the supported instruction set, rather than by speed, shape, or power use.
