That YouTube video, however informative it may have been, was pretty hard to follow due to the fast-paced explanations and the narrator’s accent. I found it extremely interesting, but it was definitely something you’d have to watch a couple times to fully understand what exactly they are trying to say. They explained what we learned in lecture…the transition from ARPANET to the Internet that we know today. I found it amazing just how much the Internet has progressed, especially since the 1990s and the start of the century. This video was created in 2009, and even since then, so much has progressed. We take it for granted, but so much has gone into the backbone of what we know today as the Internet. It has been such a huge influence on society as a whole, and has contributed large amounts to keeping in touch with others around the world. I enjoyed learning about early systems, and the interface message processor connecting to the mainframe, showing that a small appliance connected to a bigger one, to create a whole series of networks. My favorite part of the video was all of the illustrations and diagrams, especially the ones showing how everything is connected together. Back in the day, knowledge was only transferred by people, but due to the Internet, we can now find it digitally at the click of a button.
Today we don’t even think twice about sending emails, searching the web, tweeting pics, or tagging friends but as explained in “History of The Internet” 50 years ago the Internet was just an idea. Like others in the class I found myself having a hard time following everything that was being said but after watching it again I was able to come to a better understanding. In the video we learn that the launching of Sputnik 1 during the Clod War in 1957 lead to the US creating Defense Advance Research Project Agency.
After years of advancement in computer technology computers got smaller and were more easily manufactured. Similar to what was covered in lecture the video states that TCP/IP guaranteed compatibility between networks and merged them to create the Internet. I found it interesting that countries were able to work together and through network exchange create the Internet. Finally, on February 28 1990 ARPANET hardware was removed and the Internet was up and running. This video mixed a lot of technological terms with some history and after watching it a couple times I feel like I was able to grasp key points and really understand how far the Internet has came over the past 50 years.
This video had a very good way of explaining the main concepts, and especially at showing. The images helped understand both what was happening, and what they were trying to avoid (ex: the scene about decentralization, with blowing up one tower, what that would do to the network, then displaying how they combated that threat). All of this sounded like a good review of what we went over in class.
The one thing that put me off guard though, was the part about IMPs. I am a little confused about the point of the mainframe, if they have another computer that is doing all the work, and controling network activities. Why did they need two different mechanisms for what seemed to be doing what one computer was capable of?
I suppose I’m thinking from the 21st century, with mini computers for phones, but I did have to go back over that portion of the video and try to understand a little more clearly.
To think that in just 50 years, what started out as one machine only being able to perform one task at a time is now a device that can run several operations simulateneously, is a phenomenon that did not place as strong of an impact on me until after watching this video. I knew that the computer and the capabilities of the internet had improved to a large extent, but the scientific history, complexity, and obstacles that came in the way did not come to mind as much. This video, although hard to understand at times due to myself never having a great interest in the sciences, made me realize the successes and feat that people have made, in order for the evolution of the internet to occur and result in how it works today.
After reading Alyssa’s response, the immense progression and technological advancement that the internet has made really hit me. I truly remembered typing in my screen name and password, and then waiting for the dial tone, the rings, and the connection, as if I were calling somebody on the phone. And she is certainly corrent about the impatience that many have now when it takes more than a few seconds to get onto a site. I am fascinated by the dynamics that goes beyond what ordinary users of the internet like myself already know and am very interested now in learning more about the complexity that goes into the internet.
