What is Mutual Exclusion?
Answer
Mutual Exclusion is the absolute mathematical guarantee that only one thread can physically execute inside a shared critical section at any given millisecond.
Mutual Exclusion (Mutex) is the absolute foundational law of concurrent programming. It physically and mathematically prevents catastrophic Race Conditions by aggressively locking a Critical Section of code, ensuring that if Thread A is modifying a shared variable, all other threads are violently blocked from entering.
