Data Communication and Networks

Question: Discuss about the Data Communication and Networks. Answer: Introduction In this report, the researcher has identified that Cisco Packet Tracer is a network monitoring and implementation tool. Now the researcher implementing a network diagram for the given scenario. In this report, every success of evidence is address with the justification. Here the researcher, use four types of devices to implement this network architecture such as Cisco router 1841, switch, server and PCs. This research report also includes the important functionality of the Cisco packet tracer. The identification of network monitoring tool The Cisco packet tracer is one of the best network design and monitoring tool for networking. In this application, a user can draw a network architecture by the available tools in this application (Hua and Lucas 2015). There are many Cisco product, which needs to drag and drop onto the canvas and connect them via the available connecting wires. These wires are used according to their requirements such as a switch and PCs connect through a copper cable connection. Figure 1: Cisco Packet Tracer Interface (Source: Created by author) Figure 2: Cisco Packet Tracer Simulation Tool (Source: Created by author) These devices contain CLI, CMD, simulation and GUI form that is used to configure as configured in real word configuration (Mohammadi and Murray 2013). Here a user can configure a demo of their real world network architecture where without any a headache they can test their network architecture plan. Key Features of Cisco Packet Tracer The Cisco packet provides supplements genuine hardware and empowers amplified learning opportunities past physical classroom difficulties. Underpins addresses, gathering and individual labs, homework, appraisals, contextual analyses, recreations, and rivalries. Reproduces consistent, continuous redesigns of hidden system rationale and exercises. Makes educating less demanding by giving a free, multiuser environment for educators to effortlessly show specific complex ideas (Hua and Lucas 2015). Engages understudies in investigating ideas, conduct analyses and testing their comprehension. It provides writing of learning exercises, undertakings, labs, and complex evaluations. Advances social learning through a system proficient (shared) application with open doors for the multiuser rivalry, past substitute teacher collaborations, long range interpersonal communication, and gaming (Wang and Chen 2014). Figure 3.0: Showing the supported protocols (Source: Hua and Lucas 2015) Now come the integrated functionality of Cisco packet tracer where two types of works space available such as logical and physical (Mohammadi and Murray 2013). In this application, the users can draw logical network topology by clustering the network tools. The physical workplace allows a graphical presentation of logical network topology. By this physical dimension, the users can get the sense, how the network devices such as a switch, router, firewall and hosts works and looks in the real environment. Figure 3: Server (Server: Created by author) The Network Implementation Now using this network-monitoring tool the researcher implement the logical topology of a city, where an ISP is used to provide the IP address to the hosts (Elias and Ali 2014). The ISP has a range of IP 172.16.1.1 to 172.16.1.125. Here this ISP cannot provide any IP address out of this range. In the below figure 4, showing this configuration. Figure 4: Showing the DHCP configuration of server device (Source: Created by author) Now the researcher configures this server as the DNS server, where a host can browse a website through the web browser (Archana 2015). Here this functionality is showing in few figures underneath. Figure 5: DNS Configuration (Source: Created by author) Figure 6: Functionality of Cisco PC Desktop (Source: created by author) Figure 7: Cisco Web Browser (Source: Created bu author) Figure 8: The logical topology (Source: Created bu author) Conclusion In the report, the researchers find that Cisco packet tracer is one of the useful network monitoring application. This application is used in the above all implementation and definition the tools. Here the researchers provided documentation for a huge range of supportive protocols, device, command prompt and GUI forms. The researcher implemented a network diagram for the given scenario. However, in this report, every success of evidence are addressed with the justification. After all assumption the feature of Cisco packet tracer, it can be concluded that this application includes all networking concept including physical and logical structure.
