Hi,
I would like to clarify something regarding one of your articles:
http://www.webhostdir.com/news/arti...ticle.asp?id=30
You mention that a WAN is the Internet. I will have to disagree. I think a WAN is the public phone system, as your network is NOT a WAN until you use the public phone system. So if you have a network in NY and one in Texas and you never use the phone system at all between the two, then it is still a LAN, as it is never a WAN until you use the service of the phone company. Once you use the phone company, then it is a WAN, and that is why I say a WAN, is really more the phone system, as that is what makes up the Internet. No phone company (lines, etc..) No Internet.

WAN = Wide Area Network, e.g. a network which spans more than one facility, business, or home.

I know what Wan stands for, but your network is only a wan when you use the public phone system. It is in the books, or that is what the books say, I have had a class on this and boy did they get into it.

I'm afraid Curtis that I would have to disagree with you and go more along with JTY.
A Wide Area Network is more about long distance, gateways, security than it is about a phone system. In the olden days it was about the phone system but WANs can apply to phones line, VPN, private long distance networks and the internet etc. The expression WAN is more about the fact that you have a long distance between two LANs with additional security and packet routing i.e. you don't want local LAN traffic wondering across a WAN to the other LAN if it is not necessary.
However, I would not associate the internet and WAN together since unless you have at least two LANS communicating across the internet.

Then you need to tell this company they are wrong: http://store.westnetinc.com/wnstore....asp?pf%5Fid=49 and all of my teachers, which the one I have has been teaching this for like 15 or 20 years.
If you think of it, how can you contact ANYONE without using the pone system? There is no way to get to every place in the world without using the phone system, that is what the Internet is made up, the back bones, we all use the phone company. That is why their are millions of miles of phone line, that is how you get your data from one place to another, every company uses the phone company.

Curtis,
There are companies out there that transport data across long distances, and aren't telcos. For instance, Metromedia only deals in dark fiber, and they carry data, but they're not a telco.

Then it is still considered a LAN, not a WAN. But then again, who determines what those meanings are, we the people, so who knows what is really right?

I think it's splitting hairs.
When you connect two or more previously separate LAN's IMO you get a WAN.
How that connection is made doesn't matter.
Only a small portion of today's major phone company's lines are used for voice. AT&T, Sprint, MCi etc have major data-only trunks and as pointed out above there are specialty companies that handle just data. So going via a phon carrier doesn't mean a lot anyway.

That is all they have between the CO's now, are T1's lines, they replaced them all.

I think this arguing is getting pointless....
When the term WAN was originally created the only long distance data transport medium was the telco... but, in this modern day and age, networks can be interconnected via various mediums, in some cases even ethernet when you start to deal with things like telco hotels....

Lets wrap this up. It really is going nowhere:

From internet.com, webpedia: WAN - A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. The largest WAN in existence is the Internet. |
