Suppose that we have the following three 4-bit words in a packet to transmit via UDP protocol: 1101, 0101, and 0111.  Question (1) What should be the checksum to be transmitted in the packet? Question (2) If the receiver gets the checksum with no errors and the three words in the packet are, 0101, 1101, and 0111, which are in the same order as they are transmitted, then, based on our UDP or Internet checksum method, what would the receiver say about the received packet? That is, are there errors introduced into the packet?

Let Rs and Rc be the rate of each link as shown in the figure above. In case of Rs Rc, The backlog of bits at the router waiting for transmission to the client will grow and grow. Assume the throughput of this network is found to be P bps. The time it takes to transfer a file of F bits from server to client in the above network should be .  (First blank must be a relational operator like =, >, =,

There is a 0.9968 probability that a randomly selected 50-year-old female lives through the year.  A Fidelity life insurance company charges $226 for insuring that the female will live through the year.  If she does not survive, the policy will pay out $50,000 as a death benefit.  If a 50-year-old female purchases the policy, what is the expected value?
