LEARNING SWITCHES $-$ BASIC

Consider the LAN below consisting of $10$ computers connected by two self$-$learning Ethernet switches. $($You may want to re$-$read section $6\mathrm{.}4\mathrm{.}3$ in the

$8$th edition textbook$).$ At $t=0$ the switch table entries for both switches are empty. At $t=1,2,3,$ and $4,$ a source node sends to a destination node as

shown below, and the destination replies immediately $($well before the next time step$).$

Assume that the following transmissions occur $($the transmissions in reply occur but are not shown in the list below$)$:

$t=1$:$GI$

$t=2$:$AC$

$t=3$:$EA$

$t=4$:$IB$

$1.$ At t$=1,$ what is the source entry for switch $1?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$2.$ At t$=1,$ what is the destination entry for switch $1?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$3.$ At t$=1,$ what is the source entry for switch $2?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$4.$ At t$=1,$ what is the destination entry for switch $2?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$5.$ At t$=2,$ what is the source entry for switch $1?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$6.$ At t$=2,$ what is the destination entry for switch $1?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$7.$ At t$=2,$ what is the source entry for switch $2?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$8.$ At t$=2,$ what is the destination entry for switch $2?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$9.$ At t$=3,$ what is the source entry for switch $1?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$10.$ At t$=3,$ what is the destination entry for switch $1?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$11.$ At t$=3,$ what is the source entry for switch $2?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$12.$ At t$=3,$ what is the destination entry for switch $2?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$13.$ At t$=4,$ what is the source entry for switch $1?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$14.$ At t$=4,$ what is the destination entry for switch $1?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$15.$ At t$=4,$ what is the source entry for switch $2?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

$16.$ At t$=4,$ what is the destination entry for switch $2?$ Format your answer as letter,number or $\text{'}$n$/$a$\text{'}$

Can I have an explaination on how to solve this problems.
