Consider computer$1,$ computer $2$ and computer$3$ that communicates via $($LAN$1,$ router$1),($LAN$2,$ Router$2)$ and $($LAN$3,$ Router$3),$ respectively.

Assuming that computer $1$ wants to communicate with computer$3.$

The frame sending by the computer $1$ was

$\backslash$table$[[C,D,48,51,$Data$]]$

The frame received by the computer $3$ was

$\backslash$table$[[K,L,48,51,$Data$]]$

The question is to specify the logical and the physical addresses of computer $1$ and computer$3.$

Now, all computers were in the same network and communicate using bus topology. Assuming that computer$1$ wants to communicate with computer$3.$

a$)$ Draw the network and show the contents of frame in each computer $($computer$1,$ computer$2$ and computer$3).$

b$)$ In this case, does computer $1$ need the logical address to communicate with computer$3?$ Why?

Note That: Computer $2$ has: Physical address$=$E$,$ Logical address$=17.$
