History & the underlying technologies


           Internet and network is the same thing. This week, I learned about the history & the underlying technologies. I don’t really understand about this topic. Even before this I already learned about this, but I still can understand. But, I will tried! Internet, no one can owns it and it has no management organization. We also can touch it and we can’t see it. But, we can know if we have it. Usually, we use internet for send e-mail, upload and download anything that we like, read newspaper online and also surfing the internet. We can open social networking, YouTube, blog and anything if we have internet. We also can connect with everyone around the world. But, internet also has underlying. Physical, data link, network, transport, session, presentation and application all this, examples for layer.  

           If we open pages or web in internet, We can see above, that must have URL. That  because is assigned address on the internet for each computer. For internet provider, there have companies with access to the internet. Examples for provider are maxis, telecom, digi and so on. HTML and HTTP also part of the internet. And we also always having problem like troubleshooting internet connection, this happened when connection too slow. This happened because they try to power-cycle the router and modem. So, even I write this, I only understand a little bit from what Mr. Azam teaches us. That because something it really hard for me to understand about IT.
