Consider an anonymous ring of size n. Each node v stores an input boolean value i(v). When the algorithm terminates, then every node is to store the output in its private variable. Every node knows n, in that n can be a part of code. (a) Give a deterministic algorithm to compute the global Boolean OR of all input values on the ring. (b) Show that any such algorithm requires (n2) messages. Hint: There is no need to be formal, just give convincing intuitions. Observe that if there is a leader in the network then O(n) messages can suffice.

Refer to the section on Access Controls. What is the difference between "authorization" and "authentication"? What do we use to perform each of these access control functions? What are the advantages and limitations of the different approaches?
One more requirement, from time to time words become obsolete. When this happens, such word must be removed from the dictionary. Your program must account for this also.
design a circuit that takes two 3-bit binary numbers A2A1A0 and B2B1B0 as inputs and that has single output L that is "one" if and only if A2A1A0 is less than B2B1B0. Your design can make use of NOT gates, XNOR gates, AND gates and OR gates as requir..
