📝 Computation speedup in distributed system

Q1. What is the term used to describe the reduction in execution time when a task is divided among multiple processors in a distributed system?

💡 Difficulty: easy | ✅ Correct: C

Q2. Why does adding more nodes to a distributed system not always result in proportional computation speedup?

💡 Difficulty: medium | ✅ Correct: D

Q3. Given total time \(T_{\text{total}} = (1-p)T + \frac{pT}{N} + \alpha\log(N)\) with \(T=1200\) s, \(p=0.9\), and \(\alpha=5\) s, which number of nodes minimizes execution time?

💡 Difficulty: hard | ✅ Correct: C
