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?

Question 1: True or False: [ F ] Telephone network is an example of Packet Switching network. [ F ] It is the network layer’s responsibility to forward packets reliably from the source to the destination [. T ] Flow control is required to assure that the source does not overwhelm the destination by sending data faster than they can be processed and absorbed. [ ] The key elements of a Protocol are syntax, semantics, and error control [ ] User Datagram Protocol (UDP) can guarantee data delivery. [ ] Routing decision is always required for every packet of a message at each node in packet switched network. [ ] In OSI model data link layer provides for the reliable transfer of information across the physical link; sends blocks (frames) with the necessary synchronization, error control, and flow control. [ ] The transport layer is responsible for hop-by-hop communication. [ ] Because the boundaries between layer are well defined change in standard in one layer effect already existing…
Scenario: your kid logs into the school's wireless LAN, puts in "www.google.com," and starts browsing the web (Or any other website you can think of). Clearly stating the recommended sequence for using the various routing protocols would help eliminate any ambiguity.
