BJ.9 스핀락(spinlock) 뮤텍스(mutex) 세마포(semaphore) 각각 특징과 차이 설명! 뮤텍스는 바이너리 세마포가 아니에요

#spinlock #mutex #semaphore #synchronization Three types of locking mechanisms frequently used to synchronize processes or threads! Spinlock Mutex Semaphore Detailed explanation of their characteristics and differences!! Did you think mutexes and binary semaphores were the same thing? (I used to think so too, but that's not true!) Let me explain this in detail! 00:00 Opening 00:10 What are race conditions, synchronization, and critical sections? 00:51 How can we ensure mutual exclusion? 01:19 Spinlock (feat. CPU assistance) 07:08 Disadvantages of spinlocks 07:31 Mutex 11:12 Is a mutex always better than a spinlock? 13:05 semaphore 18:03 Are mutexes and binary semaphores the same? 21:47 Notes 22:13 Closing
