medium📝 Analysis Q13 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate data transfer rate for 32-bit bus
Data rate = bus width x frequency = 32 bits x 100 MHz = 3200 Mbits/s.Step 2: Calculate data transfer rate for 64-bit bus
Data rate = 64 bits x 50 MHz = 3200 Mbits/s.Final Answer:
Both have the same transfer rate -> Option AQuick Check:
32x100 = 64x50 = 3200 Mbits/s [OK]
Quick Trick: Multiply width by frequency to compare rates [OK]
Common Mistakes:
- Assuming wider bus always faster
- Ignoring clock frequency
- Choosing based on bus width alone
