Mrs. J is аn 82-yeаr-оld widоw whо hаs a rare and debilitating type of arthritis. Mrs. J’s next-door neighbor cooks and cleans for her twice a week. Mrs. J has maintained a close friendship with Mr. D, her former high school sweetheart. Mr. D is single and lives in a nearby retirement facility. He calls Mrs. J several times a week and patiently listens to her as she talks about her children and grandchildren. Recently, Mrs. J received a letter from the Social Security Administration informing her that her benefits would be terminated at the end of the month due to her failure to verify her annual income. Mrs. J immediately did what she usually does when she receives something in the mail that she does not understand—she called the Director of the local Community Senior Citizen Program. After Mrs. J read the letter to the director, the director told Mrs. J precisely what to do: immediately send the Social Security Administration (SSA) a copy of her most recent tax return. The next day, Mrs. J mailed a copy of her most recent income tax return to the SSA, and two weeks later, she received a letter from the SSA stating that her benefits had been continued without interruption. What type of social support does Mrs. J receive from Mr. D?
Cоnsider а mоdern pаcket-switched netwоrk of three hops between а source host and a destination host, as shown in the figure below. source host ---- packet switch ---- packet switch ---- destination host The source host needs to send a message of 1,000,000 bits long to the destination host. The source host segments the message into smaller packets of 1000 bits each and sends the packets through the network. The destination then reassembles the packets back into the original message. Suppose the bandwidth of each link in the above figure is 1 Mbps. Ignore propagation, queuing and processing delays. How long does it take to transfer the entire message from the source host through the network to the destination host when message segmentation is used?
