Logical clocks are useful in computation analysis, distributed algorithm design, individual event tracking, and exploring computational progress.

Type of Logical Clocks

• Lamport Clocks - which are monotonically increasing software counters
• Vector Clocks - allow for partial ordering of events in a distributed system.
• Version Vectors - order replicas, according to updates, in an optimistic replicated system
• Matrix Clocks - an extension of vector clocks that also contains information about other processes’ views of the system
