Answer / Ram Pravesh Kumar
A spin lock is a synchronization primitive in embedded systems that allows multiple threads to wait for access to a shared resource. Unlike mutexes, which can sleep and wake up when the resource becomes available, spin locks loop continuously (spin) until the resource is acquired. Spin locks are often used in low-level kernel programming due to their fast response time but may consume significant CPU cycles.
