Review Questions

• How did Leslie Lamport's concept of logical clocks change the way we understand event ordering in distributed systems?
  • Leslie Lamport's concept of logical clocks introduced a way to order events in a distributed system without relying on synchronized physical clocks. This framework allows processes to assign timestamps to events based on their interactions, thus creating a partial ordering of events. It significantly enhances our understanding of causality and enables more reliable communication and coordination among distributed processes.
• Discuss the significance of Lamport's Paxos algorithm in achieving consensus in distributed systems, particularly in unreliable networks.
  • Lamport's Paxos algorithm is crucial for achieving consensus in distributed systems, especially where network reliability can be uncertain. The algorithm ensures that multiple nodes can agree on a single value even if some nodes fail or send conflicting information. This capability is vital for maintaining consistency and reliability across various applications, including databases and fault-tolerant systems, making it one of the cornerstones of modern distributed computing.
• Evaluate how Leslie Lamport's contributions have impacted both theoretical and practical aspects of distributed algorithms in today's technology landscape.
