Practice

1. What is the main purpose of ARM architecture?

easy

A. To build large data centers

B. To design high-power desktop CPUs

C. To develop software applications

D. To create efficient and low-power processors

Solution

1. Step 1: Understand ARM architecture goal

   ARM architecture focuses on making processors that use less power and work efficiently.

2. Step 2: Compare options with ARM's purpose

   Options B, C, and D do not match ARM's focus on low power and efficiency.

3. Final Answer:

   To create efficient and low-power processors -> Option D

4. Quick Check:

   ARM = efficient, low-power processors [OK]

Hint: ARM is known for low power use and efficiency [OK]

Common Mistakes:

• Confusing ARM with high-power desktop CPUs
• Thinking ARM is for software development
• Assuming ARM is for large data centers

2. Which of the following best describes the instruction set used by ARM processors?

easy

A. Reduced Instruction Set Computing (RISC)

B. Complex Instruction Set Computing (CISC)

C. Very Long Instruction Word (VLIW)

D. Explicitly Parallel Instruction Computing (EPIC)

Solution

1. Step 1: Identify ARM instruction set type

   ARM uses a simple and efficient instruction set called RISC.

2. Step 2: Match options with ARM's instruction set

   CISC, VLIW, and EPIC are different instruction set types not used by ARM.

3. Final Answer:
