Q. What are the advantages of token(with rings) passing approach ?

i) One processor as coordinator which handles all requests
ii) No starvation if the ring is unidirectional
iii) There are many messages passed per section entered if few users want to get in section
iv) One processor as coordinator which handles all requests
v) Only one message/entry if everyone wants to get in

Q. What are the characteristics of fully distributed approach ?

i) When responses are received from all processes, then process can enter its Critical Section
ii) When process exits its critical section, the process sends reply messages to all its deferred requests.
iii) It requires request,reply and release per critical section entry
iv) One processor as coordinator which handles all requests
