Communications and Networks

Essay:

Since the past until now the technology has been updated from day to day specifically from the bottom to the top. 

For this assignment it makes me become like an architecture since I can know how to create a diagram with many different types and styles which related to our daily life.

Back to this essay, I will talk deeply about the diagram that I created. First of all, the component that I use for communications in network are router, access point, Ethernet switch, ISP, firewall, phone, PC, notebook, printer and iPad. Moreover, I chose router as my communication device to connect to my ISP because router is very popular for home or business network and it can connect to multiple computer plus many other router all along together. Needless to say, router is also available on any size of network. Furthermore, transmission media that I use for the communication device is wireless transmission media with the reason that it would be much easier once the installation finish. Yet, it send communication signal through the air or space. On the other hand, for some reasons that i use network topology to connect to multiple device is that it can speed up the distance a signal that travel between devices and it can eliminates traffic problem in link sharing. Moreover, it has privacy and security which make me feel more comfortable to use plus point to point links make fault identification easy. Another thing is that network topology also comes with both advantages and disadvantages, the disadvantage is that entire network go down if central main part fails. The other problem is that the installation and reconnection of network topology are difficult to install or connect. Another point is that communication standard that I use in my network architecture is Ethernet switch. Back to another point is that I will talk about the advantage and disadvantage of building this network to my home. Therefore, I will talk about its advantage which I can use to surf Internet at my home whenever I want with Wi-Fi or by router that also can connect to desktop computer. Especially with the Wi-Fi in my house, I can connect to my phone, electronic devices and the other members in my family can use also. Because my house use unlimited Wi-Fi Internet, it make me feel free and comfortable to use because I don’t need to go outside for Internet. In addition, I can use my printer and fax machine which need to connect to Internet. The main advantage is that multiple users can interact with each other and share any file at the same time. In contrast the disadvantage of home network is that sometimes it make me lazy and crazy about Internet at my home. For the first day that my house connect the Internet, i usually didn’t go to school because of Internet but now I stop doing that I just play only when I have free time or at my weekend. The disadvantage is that sometime I find it hard to connect to Wi-Fi Internet so it make me curious when I can not use the Internet when I really need it. More than that sometime I find it difficult to use the Internet with my Wi-Fi because of the weather, I usually notice that when it is raining, the Wi-Fi connection usually fail. By the way, the network fail can cause to lose my data or resource that I really need so I need to be careful of it. The final point is that the communication software that I might use to transfer data is email because it can send message or any files through Internet to each other and it is very popular for many users. Instant message also the one that I like to use because it is real time messaging that we can exchange file, message, audio, picture or video with the other online user by using Internet. The last communication software that I use to transfer data is FTP (File transfer protocol), it is the most common one that we usually use because it can upload or download file on the computer through Internet.
All in all, by writing this essay and doing this assignment I can understand and know a lot about communications and network which I am not so clear with it since I was young. Thus I think it make every student know more about it. We can and we will understand every chapter because the instructor always give us an assignment for each chapter.
Reflection Paragraph:
This assignment teach me a lot by show how to create many kind of diagram by our own or using template. Creately.com provide us various categories to create a diagram, so it make us easy to create because it has template to follow. We can add picture, text, line, color or many others to create a diagram as we want. To conclude this I like that website very much and it is very important for me to use and know not only in the present but also in the future. I will recommend it to others. Compare to the other network diagram of my friend, I think all of us has a similar structure of creating a network. In addition, I think my network diagram is not good enough. It is just the simple one, but one of my friend, he created the diagram that he will use in the future and it look like a large home network to me. So I think i will need to add or change some part like him because it is necessary for me to know from now on. I will try to improve and develop it to become much better.
