Q. Define Wait protocol?
The wait protocol is used for resolving conflicts that arise due to some multiprocessors requiring same resource. There are 2 kinds of wait protocols: sleep-wait and busy-wait. In busy-wait protocol process stays in process context register that continually attempts for processor availability. In sleep-wait protocol wait protocol process is removed from processor and is kept in wait queue. The hardware complexity of this protocol is greater than busy-wait in multiprocessor system. If locks are used for synchronization subsequently busy-wait is used more than sleep-wait.
