Lab assignments for chapter 9we have created one lab assignment for this chapter, lab9-1. we have also included one lab report sheet, which means that each lab should be reported on a separate sheet. it is assumed that you have done the lab assignment for chapter 1, which told you how to install the wireshark software and how to use it. the assignment is about an auxiliary protocol, arp, which is part of the network layer, but it is used as a liaison between the network and the data-link layer. arpas we discussed in the textbook, arp is an auxiliary protocol that maps the ip address of the connection to the host or router to the link-layer address of that connection. in this lab, we trace and examine arp packets9.1.1 assignmentstart your web browser and clear the browser’s cache memory, but do not access any website yet. open the wireshark and start capturing. go to your browser and retrieve any file from a website. wireshark starts captur- ing packets. in the filter field of the wireshark window type arp (lowercase) and click apply. stop capturing and save the captured file. part i: arp request messagefrom the packet list pane, select the first arp request packet. from the packet detail pane, select the address resolution protocol. questionsusing the hexdump and consulting figure 9.8 in the textbook, answer the following question in your lab-report sheet. from the hexdump, determinethe hardware type.12the protocol type. the hardware length. the protocol length. the value of the operation field. what is the meaning of this field? the source hardware address. the source protocol address? the destination hardware address. the destination protocol address? using the packet detail pane, verify your answers to the first question. what is the type of the destination hardware address (unicast, multicast, broad- cast)? which hardware interface does the destination address define? checking the packet byte pane, you will notice that the arp request is followed by zero-bytes. how many 0s are there? explain the reason for the existence of these 0s. part ii: arp reply messagefrom the packet list pane, select the first arp reply packet. from the packet detail pane, select the address resolution protocol; the packet’s hexdump will be highlighted in the packet byte pane. questionsusing the hex dump answer the following question in your lab report sheet. using the hexdump, determinethe hardware type. the protocol type. the hardware length. the protocol length. the operation code. the source hardware address. the source protocol address? the destination hardware address. the destination protocol address? using the packet detail pane, verify your answers to the first question. what type of address is the destination hardware address? what network interface does the address define? 9.1.2 lab 1 report sheet9.1.3 documents to turn into d2l dropboxthe lab9 lab 1 with answered questions in pdf or word format. make sure to add a screenshot of the supporting captured arp information.

3. (6 pts) internally in the computer, with few exceptions, all numerical computation is done using binary numbers. output, however, often uses ascii, which is formed by appending 011 to the left of a bcd code. thus, an algorithm that directly converts a binary integer to a bcd integer is very useful. here is one such algorithm 1) draw lines to the left of the binary number to bound the expected bcd decades. (each decade is a group of 4 bits.) move the binary number one bit to the left. add 0011 to each bcd decade containing a binary value> 0100 repeat steps 2-3 until the last bit in the binary number has been moved into the least significant decade position. (note that when the last bit has been shifted into bcd decade, step 3 is not repeated.) read the bcd result. 2) 3) 4) 5) a) execute the algorithm for the binary number 1101101 b) execute the algorithm for the binary number 01110101110 4. (4 pts) represent the decimal number 3568 in bcd; excess-3 code; ascil; and hex.
