please solve this with extra explanation. tnx Task $($ARQ$)$: Using the one$-$way stop$-$and$-$wait protocol, how long will the transmitter at least wait for the acknowledgment of a sent frame of size $20$ kbit $,$ with a transmission speed of $\backslash (10\backslash$mathrm$\{$Mbit$\}/\backslash$mathrm$\{$s$\}\backslash )$ and a propagation delay of $1$ mas between the locations where the transmitter and receiver of the frame are lgated $3$ Ignore the confirmation size when calculating.

Task $($OSI$/$TPC$/$IP model, PDU$)$: The figure shows an example of a data link layer frame implemented by the Ethernet standard. What is the MTU $($Maximum Transmission Unit$)$ value for the given local network, assuming the frame is full length?

Task $($IPv$4)$: PC $4$ wants to check the availability $($ping$)$ of PC $1,$ which requires sending an ARP request first. PC $4\text{'}$s default router is Router $2.$ What is the destination address of the ARP request sent from PC$4$ and what is requested by this request?

Task $($fragmentation$)$: We want to transmit $9910$ octets of data on a link from point $\backslash ($ A $\backslash )$ to point $\backslash ($ B $\backslash ),$ which are $600$ kilometers apart. The maximum frame size is $2118$ octets, with the size of the data field in the frame being $2100$ octets. The communication infrastructure over which the communication takes place includes a transmission medium with a bandwidth of $\backslash (8\backslash$mathrm$\{$Mbit$\}/\backslash$mathrm$\{$s$\}\backslash )$ and a propagation speed of $\backslash (2^\{*104\}8\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ How long does it take in total $($in seconds$)$ to transfer data between points $\backslash ($ A $\backslash )$ and $\backslash ($ B $\backslash )?$

Task $($routing protocols$)$: For the networks in the figures, fill in the routing tables for routers R$1,$ R$2,$ and R$3.$ Fill in the routing tables when the immediate router realizes that the connection has been lost. The routers use the RIP protocol.
