Q. Define Optimistic Synchronization?
Optimistic Synchronization: This method too updates atom by requester process however sole access is granted after atomic operation by abortion. This scheme is also termed as post synchronisation. In this method any process can secure sole access after first finishing an atomic operation on a local version of atom and then executing global version of atom. The second operation guarantees concurrent update of first atom with updation of second atom.
