I thought the video was a nice little recap of how the Internet came to be. The visuals were really cool and helped me understand what he was talking about when he was talking about them. I liked how he split up the topics based on the major areas of concentration, such as military, science and consumer.
I liked that he didn't go into detail on certain things that led to other more efficient things, like the NCP. I disliked that he didn't touch on RAND at all after bringing it up. And I didn't get why ARPANET was science and not military when it was created by DARPA.
I got confused when he talked about time sharing. Did that lead to the creation of an IMP subnet or are they separate connection types? It was kind of weird that when he started talking about atomic conflict, the audience was to assume to have known there was a centralized architecture within the network. Where was the center, at an IMP?
The Cyclades stuff confused me, too. The physical layer in the hardware in which the computers "didn't intervene but served as a transfer node" was hard to make sense of with the information given before that. The term "computer" was used so loosely and I didn't know what it applied to. Was it the mainframe, an IMP, or something similar to a modern computer? And the description of the OSI and how it merged with the TCP protocol seemed to be for within a network, since that's when the TCP protocol was described, but it's supposedly an inter-networking system? Does each computer on the diagram represent a network then? And what are the layers that the channel was divided into?
So yea, I'm a bit confused, haha. I hope I wasn't the only one.
I wasn't initially confused about the use of the word 'computer' but when I read your post I realized that the whole time I was picturing a modern laptop every time the narrator said computer which I know is probably not what he meant.
ReplyDeleteThe narrator should have been more careful with their terminology. Maybe the video would have been more interesting or clear if they had specifically talked about the physical computers...because in my opinion, that would be just as interesting as learning about the networking!
