Memory Consistency

Memory consistency refers to the rules that govern how multiple processors in a computer system see and interact with shared data stored in memory. When different processors perform operations, memory consistency ensures that they agree on the order of those operations. This is important for maintaining accurate and predictable behavior in programs. Without proper consistency, one processor might read outdated or incorrect data, leading to errors and unexpected outcomes. Essentially, it helps coordinate how information is shared and accessed across multiple parts of a system, ensuring reliability in computing tasks.
