Question 1

True or false: ARM chips consume more power than x86 chips in equivalent performance scenarios.

Accepted Answer

False. ARM chips are typically more power-efficient than x86 at similar performance, which is why they dominate mobile devices.

Question 2

True or false: ARM chips can run x86 software without any modification or emulation.

Accepted Answer

False. ARM uses a different instruction set than x86, so software must be recompiled or emulated to run.

Question 3

True or false: ARM stands for Advanced RISC Machines, originally Acorn RISC Machine.

Accepted Answer

True. ARM was originally Acorn RISC Machine, later renamed Advanced RISC Machines after the company split from Acorn.

Question 4

True or false: ARM processors are exclusively used in smartphones and tablets, not in servers.

Accepted Answer

False. ARM is increasingly used in servers, like AWS Graviton chips, due to energy efficiency and performance gains.

Question 5

True or false: The ARM architecture uses a load-store model where only load and store instructions access memory.

Accepted Answer

True. This is a defining RISC feature: data must be loaded into registers before being operated on, then stored back.

Question 6

True or false: Apple's M1 chip is based on the ARM architecture but uses a custom instruction set extension.

Accepted Answer

True. Apple's M1 uses ARMv8-A with custom extensions like its own GPU, Neural Engine, and memory controller.

Question 7

True or false: The ARMv9 architecture introduced Scalable Vector Extensions (SVE) for enhanced AI workloads.

Accepted Answer

True. ARMv9 added SVE2, building on SVE from ARMv8, to improve vector processing for AI and machine learning tasks.

Question 8

True or false: ARM processors have a built-in hardware random number generator in all Cortex-A cores.

Accepted Answer

False. Not all Cortex-A cores include a hardware RNG; it's optional and varies by implementation from chip makers.
