Computer communications & Networks - Lab Report ExampleIn order to test connectivity of the Internet fellowship, ping command is penalise from the command prompt of the operating system. The sentence structure will be ping (space) ( conclusion address), moreover, in order to follow-up hops and delays in accessing the X stream server, the tracert command can be executed from the command prompt. The syntax for this command will be tracert (space) (destination address). The ping command utilized Internet Control Message protocol (ICMP) to check the connectivity of the destination by move ICMP echo request on periodic basis. Moreover, the tracert command demonstrates either the hops and delays that are in the way of that particular destination. Likewise, it is not necessary that only routers are twisting in the process of establishing and exchanging information from the required host. The Ethernet is the first device that initiates and constructs a request datagram from the home figurer, as it is considered to be the most popular Local Area Network technology that is implemented globally (Ethernet. 2007). The connectivity of the Ethernet organizer is established by both wired and wireless meshworks. However, in terms of wired connectivity, twisted pairs of product line are connected in to the Ethernet RJ45 socket. The other end of the wire is terminated to the router, switch or hub. In this scenario, home user will use a DSL router that will connect the home computer with the Internet Service Provider (ISP). Likewise, the Ethernet construct the datagram consisting of six parameters i.e. destination address, source address, preamble, type, CRC and data. The preamble parameter is prudent for clock synchronization of the data packets from the source and destination. Likewise, the addresses... This report approves that home Internet users do not consume DNS configured. ISP is responsible to resolve the URL into IP addresses. In order to do so, the request from the home network will terminate on the ISP Network that will resolve the URL and sends the request to the relevant destination accordingly. After resolving the DNS for the URL, the router checks for the shortest and robust path for processing the quest with the help of routing protocol. Some popular routing protocols hold Routing Information Protocol, Open Shortest Path First, Border Gateway Protocol. After identifying the most suitable path for the request, the connection to the X stream server will be established. Encapsulation of User datagram protocol, IP and Ethernet takes place before sending it to the router for resolving DNS query.This essay makes a conclusion that the first section covered mandatory requirements as wellhead issues that occur on physical layer connectivity. Likewise, we birth discussed the Ethernet packet header along with its purpose in details. The next discussion was about CSMA/CD, as the request needs space to fulfill the execution. Next we pee- pee discussed the ARP command along with the discussion of a MAC address packet. Moreover, in the next section we have discussed the network layer connectivity and router functionality. We have also put some light on routing protocols and their functions. Furthermore, in the net section, DNS query construction is discusses along with socket connections by incorporating HTTP, TCP/IP, UDP and ARP for opening the X stream web foliate on the home user browser.
