A Succinct Definition of the Internet?
magnamous asks: "Ever since Senator Ted Stevens used the phrase 'series of tubes' to describe his understanding of the Internet, I've noticed several stories and comments referencing how silly that is. Although I agree that that description is rather silly, each time I've found myself trying to come up with a -succinct layman's definition- of what the Internet is, and I come up short. Wikipedia has a gargantuan page describing the Internet, and Google's definitions offer pretty good descriptions of what the Internet is in a functional sense (with some throwing in terms that the layman wouldn't understand, or take the time to understand), but not really a good description of what it -is- in the physical sense that I think Sen. Stevens was trying to get at. What are your suggestions for a succinct layman's definition of the Internet?"
I know some would say that laypeople should take the time to learn the technical, more accurate meaning of what the Internet is. The problem is that they won't. We all know laypeople. I live with two of them. When you start talking about 'TCP/IP' or 'DNS', or if you get far enough to start describing those terms, their eyes glaze over. That's what makes them laypeople — they don't care about the subject enough to learn about it in-depth; if they did, they'd be computer enthusiasts. So please keep in mind that, in order for this discussion to be useful, 'succinct' and 'layman' are essential parts to any definition of the Internet given here. Also keep in mind that 'succinct' doesn't necessarily mean one sentence; a relatively short paragraph would be fine, too — the main goal is to come up with something that physically describes the Internet in a way which laypeople can actually understand."
The internet is a collection of ideas, presented to users in a vast array of increasingly easier to use methods, by a plethora of individuals, groups, small businesses, corporations and governments, for multiple purposes involving money, fact and/or opinion. No single group of aligned parties shall control the Internet, or the Internet shall be no longer valid.

How about "bunch of computers connected using phone lines"?
It's pretty much a telephone system, except that it's computers calling other computers. Most people have a basic understanding of the workings -- if not the mechanics -- of a phone system.
licet differant, aequabitur
I thougth the "tubes" analogy was fine, myself. I don't know why people got on his case about it.
Usually when i try to describe the internet I liken it to the mail system. You have "envelopes" that are addressed to someplace. Then they get picked up by someone, thrown on a truck, routed etc. It's basically the same thing that happens with packets as they get routed.
As far as the WWW goes, that's a different and distinct thing that's built on top of the Internet. I don't think it's really that hard to explain. It's just like a library or newspaper basically.
If you want to get into the finer social implications.. then that's another story, but the basics, I think, are easily understood in terms of familiar concepts.
Physical: The Internet is a collection of computers that send each other messages, along with the equipment that carries the messages. Social: The Internet is a virtual community where people can get together, do business, and share ideas and culture. Functional: The Internet is a way you can use computers to send family, friends, and co-workers letters, pictures, and movies. Technical: The Internet is a collection of computers following protocols conforming to the OSI model that enable computers to communicate with each other. ...

We're already at that point, unless you happen to live in an African tribe or similar. 10 or 15 years ago, this "what do we say to laymen?" question may have had some relevance, but now it does not. Everyone I know either uses the internet, or at least knows what it is, and this isn't just geeks or nerds, it's 75-year-old retired people, disabled people, and assorted other totally non-technical people. In developed countries, especially those speaking English (since we are discussing an English definition after all), there's almost no one left who doesn't know by now what the internet is.
It's true, these people may not understand exactly what it is on a low level, like what backbones are, what companies own them, what TCP/IP is, etc., but just like with airplanes, they know the important stuff: that it's a "network" connected to their computer that they can use to access email, websites, and other services. These nontechnical people use the internet every day for reading their email, buying stuff on Amazon.com, checking out their favorite discussion forums, etc. They don't need a definition for the "internet". They already know what it is. That some stupid politician doesn't know, or feels some need to create a definition, is utterly pathetic.
That's a really good definition. You are right that the key observation is that the technological means by which all of the computers are connected and the protocols they use are not important.
However since we are defining The Internet and not merely any computer network (to which your definition would apply), you should mention that this is a globally connected public system.

I know people joke about the series of tubes thing, but it seems to me that was the least wrong part of Stevens' totally confused statement.
Politics aside, I don't really see the technical problem with comparing the Internet to a series of tubes. Tubes have a predictable bandwidth, i.e. you can only pump a certain amount of liquid or gas through them in a given time; and they have predictable latency, i.e. you push something in one end, it takes some time to come out the other end. So far, a lot like a network connection.
What the "series of tubes" doesn't capture is the packetized nature of the internet, or the complexities of routing, and other such details. However, at the abstraction level at which Stevens was talking, I'm not sure any of that matters. If you're talking about things like "clogging up the Internet", it's true that that can happen, for the same reasons that tubes can get clogged: if you try to put too much stuff in, at too many entry points, your backbone tubes are going to become a bottleneck. So the metaphor holds up in this case, and predicts behavior that you can see on actual networks.
The fact that the email problem Stevens was describing had nothing to do with Internet congestion is a separate issue, which doesn't actually detract from "series of tubes" as a metaphor for the Internet at a certain level of abstraction.
I'd love to hear reasons why I'm wrong. Other than "Ignore the facts, we must excoriate politicians who are against network neutrality!" Ridiculing a perfectly good metaphor just because you don't agree with the guy using it is not the way to sensible public policy, although I admit it does seem to be how politics is often conducted.
A friend of mine managed to cover this in four words over a decade ago:
"Many computers--all friends."
> I don't know why people got on his case about it.
Because of the rest of the description wherein he believed that other people downloading movies somewhere were clogging the pipes and kept his "internet" (email) from arriving on time. If you watch it in context, it's clear that he doesn't know how the internet works. As far as anyone can tell, he believed the pipes are, well, literal pipes with "internets" flowing through them. Did you ever see the full speech? Only the first line gets widely quoted any more, but the Daily Show showed the whole thing. It was ridiculous.
Anyhow, the most succinct definition of "internet" I can give you is just one word: here.
Or if you need something with more technical accuracy, it's the giant network computers get connected to because almost everyone else is also connected to it. All the internet providers link to other providers, who eventually link with everyone else, because there's not much value in having a network isolated from the rest of the world in most cases.
IN fact that's where the terminology game from. Why do you think a bunch of data is called a packet? Its cause packets are what you send through the mail, at least in the 50's thats what they were called (nowadays everyting is a "package" but that's more because the term "packet" is now more widely used electronically.
If you want to explain the internet to people, use the analogies that the original terms were modeled after!
Server - A server is like a waiter or customer service person. You ask it for something and get get sir for you. The ony difference is the server is a computer that is handling the requests.
Client - A client is like a patron or business client; he is the person asking the server for things. In the case of the internet the client is another computer, who is asking the server for something.
Packet - A bundle of information, with an address, that needs to be delivered. The packet could be going from the client to the server, in which case it is how the client is asking the server for something. If it is going from the server to the client, it is the information the server asked for.
Server, Client, Packet. Three simple words any layperson SHOULD ALREADY KNOW. It's not really hard to explain.
