Sequential Consistency

Sequential consistency is a way of ensuring that multiple processes or computers sharing data see and follow the same order of operations. It guarantees that the results of operations appear as if they occurred one after another in some sequence that all processes agree upon, even if they happen simultaneously. Think of it like reading a book: no matter who reads it, everyone agrees on the order of the chapters. This makes system behavior predictable and reliable, preventing conflicting or confusing results when multiple users or processes access shared data at the same time.
