Types of Clock Synchronization in Distributed System

Physical Clock Synchronization: Ensures all system clocks in a distributed system align with a real-world time standard, such as UTC. This is achieved using protocols like NTP or GPS-based time synchronization. Logical Clock Synchronization: Focuses on maintaining the logical order of events rather than aligning with real-world time. Algorithms like Lamport Timestamps and Vector Clocks are used to preserve causality in distributed systems. Mutual Exclusion Clock Synchronization: Ensures orderly access to shared resources by synchronizing clocks or timestamps to resolve conflicts in resource requests. This is commonly achieved using token-based or timestamp-based algorithms, ensuring mutual exclusion and fairness.
