Voorbeelden van semaphore

• By clause 6, a waiting process can synchronize with the relevant monitor and is granted access provided the corresponding semaphore is unlocked.

• Another algorithm, for proving freedom from deadlock for two transactions synchronizing with binary semaphores only was also described.

• The requirement that the semaphore remain non-negative at all times limits allocation to the available resources.

• Although it is a compound structure, it is treated as an atomic element by semaphore.

• Mutual exclusion is enforced by providing each resource with a semaphore.

• Any time a process wants to exchange data, it will wait for the semaphore.

• We focus on the interaction between processes - this interaction is through shared resources, which are given by their semaphores.

• Two important features of semaphores make them the ideal candidates for the means of synchronization for data dependency and data consistency (mutual exclusion).
