What is the formula to find disk access time?

35. What is the formula to find disk access time?

1. Disk Access time=Seek time +Rotational latency +transfer time
2. Disk Access time=Seek time-Rotational latency+ transfer time
3. Disk Access time=Seek time-Rotational latency-transfer time
4. Disk Access time=Seek time+ Rotational latency/transfer time

Answer: A) Disk Access time=Seek time +Rotational latency +transfer time

Explanation:

Disk Access time=Seek time +Rotational latency +transfer time
