February 2008[edit]

I think that we would be better off to include external links. I see several that were deleted by an editor. Personally I don't see anything wrong with any of the. They are all relevant, useful, and in my opinion provide value to the readers as a source of further information on the subject.

Networkingguy (talk) 16:06, 26 February 2008 (UTC)

Here are the list of links that was there. Thoughts?

External links[edit]

This is a very short article for a complex subject! — Catherine\talk 03:26, 10 September 2005 (UTC)

I think it's still a bit on the short side. I'll try and expand on it today or in the next few days Poweroid 15:04, 11 December 2006 (UTC)

I suggest include information about LAN adapters like 10T100

I've dropped a couple of bits that I didn't think belonged, and re-written others. I think its much better than it was - hope others agree - "snori" (

I don't think "I'll take you to the candyshop I'll let you lick the lollipop, don't hit girl don't you stop, keep going till you hit the spo ooooof" relates to LAN, so I'll take it out...

"S e x me to give me my satisfaction" also needs to go. But I don't know what to put there.

I've now simply reverted back to the version previous to those edits.--Snori 01:53, 14 June 2006 (UTC)

"snori u have done an excellent job"

glad you like it! --Snori 23:53, 14 July 2006 (UTC)

"Although switched Ethernet is now most common at the physical layer" this is incorrect; Ethernet and Ethernet switches are both second layer (data/link) items, and not "physical" (or first layer) items. see the OSI_Model or the Internet protocol suite articles for more information. --Anonymous

Quite right. Changed. --Snori 16:57, 19 October 2006 (UTC)

I've just removed someone's name that was put in by (I assume that it was put in there for "Search Engine Optimization" purposes). Looking at that person's contribution and talk page, it looks like they are vandals and have been warned. Is there anyone who can ban them? Philomathoholic 08:22, 29 September 2007 (UTC)

Deleting references[edit]

There were several references here since the early days of the article (see, for example) and when it was just a few sentences long. The current version of the article doesn't have any of that original information but the references are still being quoted. It's high time we removed them as they are not references for this article anymore. Poweroid 15:02, 11 December 2006 (UTC)

Lan design best practice[edit]

I created some pages on LAN design best practice on [wikipractice]. They are coming from the experience I acquired as a telecommunication consultant and from diverse sources I collected. Could it be possible to add them as external link ? Guy Corbaz 18:03, 24 May 2007 (UTC)

Sorry but Wikipedia is not a mere directory of links, nor should it be used for advertising or promotion. (Requestion 19:26, 25 May 2007 (UTC))

add'l comments on LAN[edit]

Why haven't you included descriptions of LAN as it relates to video??? I would like to invite you to add this to your written article please. Otherwise, this has been a great read.)


I've just chopped out an unreferenced bit regarding LL Labs having the first LAN back in the 60's. Dropped in 27Nov07 by user Sylvanwulf - his only contribution ever. Shouldn't have stayed as long as it did. Snori (talk) 09:36, 9 August 2008 (UTC)


This new section seems unnecessary to me, and much of the the wording is very odd.

  • What does "...It is designed to deal with connecting open systems to communicate with other systems..." refer to?
  • "...and they are 5 to 10 times faster than standard LANs" - what is "they"?

Snori (talk) 23:05, 1 March 2009 (UTC)

In computing, a protocol is a convention or standard that controls or enables the connection, communication, and data transfer between computing endpoints. In its simplest form, a protocol can be defined as the rules governing the syntax, semantics, and synchronization of communication. Protocols may be implemented by hardware, software, or a combination of the two. At the lowest level, a protocol defines the behavior of a hardware connection.

Jeff (talk) 00:59, 2 March 2009 (UTC)
I have removed this section. While it may be interesting to discuss protocols in connection with LAN technology, the section was just a random pile of inaccurate and incoherent verbage. I see this was removed before and reverted with claim of vandalism, which is clearly false. I advise strongly against further reversion. Kbrose (talk) 14:57, 2 March 2009 (UTC)
That’s fine with me. I don’t care about this anymore. Thank you for removing Protocols.

LAN-> Local Area Network —Preceding unsigned comment added by (talk) 11:44, 4 March 2009 (UTC)

We need more precise description of LAN. The current one: "A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, or office building" seems imprecise. — Preceding unsigned comment added by Sanchitnis (talkcontribs) 07:05, 23 November 2015 (UTC)


typically a LAN is a single broadcast segment. surely this is notable. (talk) 20:32, 7 May 2009 (UTC)

Steve Jobs on LAN[edit]

Fun little nugget:

35. Cashien 1982; Saal 1995. Saal (1995) commented on Apple's disinterest in networks: "Some people at Apple were interested in Nestar to get Apple into the business world. Other individuals, the prime example [of whom] was Steve Jobs, did not want to go into that direction and viewed this as the wrong thing. They [the microcomputers] were called personal computers because they were personal. And he viewed anything which tied machines together [as something that] was going to lead to some kind of uniformity, some kind of of central control, some kind of mainframe-like, IBM-dominated universe."

(Actually, the first commercial installation was at Chase Manhattan, at One New York Plaza, and took place in mid-September 1977... and interestingly, that installation took place under the pre-annoucement name of "INTERNET"... although the name was changed to "The ARC System" for the public announcement on Dec 1, 1977).

Local Network is a SuperSet of Local Area Network (LAN)[edit]


In his book, "Local Networks, An Introduction" by Dr. William Stallings, PhD. in Computer Science from M.I.T. in 1971, Copyright (c) 1984, Macmillan Publishing Co., Div. of Mamillan, Inc., on page 2, he defines what a "Local Network" is: "A local network is a communications network that provides interconnection of a variety of data communicating devices within a small area." It is a SuperSet of the "Local Area Network (LAN)"--the page that Wikipedia redirects one to when looking up "Local Network." I think you should get Dr. Stallings to write an article for your "Local Network" page and then redirect from it to all the different kinds of local networks he mentions.

Sincerely yours,

I am not about to change anything but your picture with the caption "How a local network using ethernet might be connected." is preposterous. Ethernet is a point to point wiring system and the picture depicts something very different. I suggest it be fixed. Arydberg (talk) 11:45, 29 May 2012 (UTC)

That's how 10BASE5 Ethernet looks. That's long obsolete though. But the picture appears in the History section that discusses this vintage of network so I have adjusted the caption but retained the picture. --Kvng (talk) 18:23, 31 May 2012 (UTC)

Leased lines in a LAN vs WAN[edit]

There is occasional confusion over what differentiates a WAN from a LAN - specially now that LANs can be very large and almost always involve a connection to the Internet. I belive that the key issue is that the owner of a LAN owns and controls all of it - i.e. does not require leased lines, satelitte, microwave or Internet. I think that this is widely understood, but not often explicitly stated. The current intro text says:

By contrast, a wide area network (WAN), not only covers a larger geographic distance, but also generally involves leased telecommunication circuits or Internet links.

I recently changed this to:

By contrast, a wide area network (WAN), not only covers a larger geographic distance, but also generally requires leased telecommunication circuits or Internet links.

This was reverted, but my feeling is that a very large campus network, perhaps with a several km fibre or private microwave link to another site is still a LAN; but as soon as a node requires a stack/path not owned or controlled by the LAN owner (say an office on site that only links to the main LAN via a VPN over an ISP-provided Internet link), it is a node on a WAN, not part of the LAN.

Are there examples of WANs which don't require such links?Snori (talk) 22:13, 28 August 2016 (UTC)

Both of these are conditioned with "generally" so either would work I suppose. I reverted because there was not a clear improvement and I could not understand the edit comment. I am not aware of hard-and-fast rules about where exactly a large LAN becomes a WAN but if you beleive there are such rules, please provide some citations. ~Kvng (talk) 14:47, 29 August 2016 (UTC)
