What are memory models in distributed systems?

Memory models define how operations on shared data are perceived in distributed systems, ensuring consistency and correctness.

Can you explain the difference between sequential and eventual consistency?

Sequential consistency ensures that operations appear to be executed in some sequential order, while eventual consistency guarantees that, given enough time, all updates will propagate to all nodes.

What are some common challenges with implementing these models?

Common challenges include handling network partitions, ensuring data consistency, and managing latency across distributed nodes.

How do different programming languages handle memory models?

Different languages have varying abstractions and guarantees; for example, Java has a well-defined memory model, while C++ allows more flexibility but requires careful management.
