Home communication involves controlling systems such as heating, cooling, and security.

Gifford's quorum consensus replication is in use at servers X, Y and Z which all hold replicas of data items A and B. The initial values of all replicas of A and B are 100 and the votes for A and B are 1 at each of X, Y and Z. Also R = W = 2 for both A and B. A client reads the value of A and then writes it to B.

(i) At the time the client performs these operations, a partition separates servers X and Y from server Z. Describe the quora obtained and the operations that take place if the client can access servers X and Y. (ii) Describe the quora obtained and the operations that take place if the client can access only server Z. (iii) The partition is repaired and then another partition occurs so that X and Z are separated from Y. Describe the quora obtained and the operations that take place if the client can access servers X and Z.
