How are OSI and ISO related to each other? ISO is the organization (International Standards Organization), and OSI (Open Systems Interconnection) is its model. Match the following to one or more layers of the OSI model: a. o!te determination " determination " #etwor$ %. &low control control " 'ransport and ata in$ c.

'he physical destination address of the frame is corr!pted d!ring the transmission. 1hat happens to the frame? How can the sender %e informed a%o!t the sit!ation? If the corr!pted destination address does not match any station address in the networ$, the pac$et is lost. If the corr!pted destination address matches one of the stations, the frame is deli+ered to the wrong station. In this case, howe+er, the error detection mechanism, a+aila%le in most data lin$ protocols, will find the error and discard the frame. In %oth cases, the so!rce will somehow %e informed !sing one of the data lin$ control mechanisms disc!ssed in -hapter 22. S!ppose a comp!ter sends a pac$et at the networ$ layer to another comp!ter somewhere in the Internet. 'he logical destination address of the pac$et is corr!pted. 1hat
happens to the pac$et? How can the so!rce comp!ter %e informed of the sit!ation? 3efore !sing the destination address in an intermediate or the destination node, the pac$et goes thro!gh error chec$ing that may help the node find the corr!ption (with a high pro%a%ility) and discard the pac$et. #ormally the !pper layer protocol will inform the so!rce to resend the pac$et. S!ppose a comp!ter sends a pac$et at the transport layer to another comp!ter somewhere in the Internet. 'here is no process with the destination port address r!nning at the destination comp!ter. 1hat will happen? Most protocols iss!e a special error message that is sent %ac$ to the so!rce in this case. If the data lin$ layer can detect errors %etween hops, why do yo! thin$ we need another chec$ing mechanism at the transport layer? 'he errors %etween the nodes can %e detected %y the data lin$ layer control, %!t the error at the node (%etween inp!t port and o!tp!t port) of the node cannot %e detected %y the data lin$ layer.
