- You want to transfer a document from one computer to another, and you want the document to be encrypted. The destination computer is on another network, so you know data has to travel through one or more routers. The network technology on your network is Ethernet, but the technology on the destination network is Wi-Fi. From what you have learned about networking, should this document transfer work? Why or why not? Which layers of the OSI model are involved in the italicized parts of this description?Q2.Part A: Suppose COMPUTER-A send a message “I will work hard in Finals” on internet to COMPUTER-B. How that communication takes place according to OSI 7 layers model? Write very short description of each of 7 layers DIAGRAM for your answers on both computers. Part B: Mentioned differences and similarities between term “TCP/IP” and “OSI Model” in your own words?1) Consider a reliable data transfer protocol that uses only negative acknowledgments. Suppose the sender sends data only infrequently. Would a NAK-only protocol be preferable to a protocol that uses ACKs? Why? 2) Besides network-related considerations such as delay, loss, and bandwidth performance, there are other important factors that go into designing a CDN server selection strategy. What are they? 3) What are the five layers in the Internet protocol stack? What are the principal responsibilities of each of these layers? List five tasks that a layer can perform. 4) Why do HTTP, SMTP, and POP3 run on top of TCP rather than on UDP? 5) List six access technologies. Classify each one as home access, enterprise access, or wide-area wireless access, and then describe how they fundamentally operate.
