Why does branching control program execution flow in ARM architecture rather than sequential execution?

hard📝 Conceptual Q10 of 15
ARM Architecture - Control Flow Instructions
Why does branching control program execution flow in ARM architecture rather than sequential execution?
ABecause ARM processors cannot execute instructions sequentially
BBecause branching is faster than sequential execution
CBecause branching allows the program to make decisions and repeat code, not just run line by line
DBecause branching replaces the need for registers
Step-by-Step Solution
Solution:

  1. Step 1: Understand sequential execution

    Normally, instructions run one after another in order.

  2. Step 2: Recognize branching's role

    Branching changes this flow to allow decisions, loops, and skipping instructions, making programs flexible.

  3. Final Answer:

    Because branching allows the program to make decisions and repeat code, not just run line by line -> Option C

  4. Quick Check:

    Branching enables flexible flow, not just sequential [OK]
Quick Trick: Branching enables decisions and loops, not just straight execution [OK]
Common Mistakes:
  • Believing ARM can't run sequentially
  • Thinking branching is about speed only
