Review Questions

• How did Leslie Lamport's work on logical clocks contribute to solving synchronization issues in distributed systems?
  • Leslie Lamport's introduction of logical clocks allowed processes in distributed systems to keep track of the order of events without relying on synchronized physical clocks. By assigning a timestamp to each event based on local counters, his approach helped to establish a consistent order for message passing. This innovation was key in addressing challenges such as race conditions and ensuring that distributed processes could effectively coordinate their actions.
• In what ways did Lamport's development of the Paxos algorithm enhance fault tolerance in distributed computing?
  • The Paxos algorithm, developed by Leslie Lamport, provides a robust method for achieving consensus among distributed processes even when some nodes fail or exhibit faulty behavior. By using a quorum-based approach, it allows a majority of nodes to agree on a value despite failures, thus enhancing reliability. This framework is essential for maintaining system integrity and ensuring that distributed applications can operate correctly in the face of failures.
