  DSN 2007
DSN is the annual international conference that directly addresses this requirement, presenting research and solutions, and posing new challenges.
The DSN 2007 conference will be held at the "EICC", the Edinburgh International Conference Centre, a superb modern conference facility right in the heart of the city, with a wide variety of accommodation options close at hand.
Indeed, as General Chair for DSN 2007, I look forward to sharing a dram of uisge beatha (Gaelic for "water of life") with each and every delegate.

  Defense Switched Network - Wikipedia, the free encyclopedia
The DSN provides the worldwide non-secure voice, secure voice, data, facsimile, and video teleconferencing services for DOD Command and Control (C2) elements, their supporting activities engaged in logistics, personnel, engineering, and intelligence, as well as other Federal agencies.
In 1982, the DSN was designated by the Office of the Secretary of Defense (OSD) and the Joint Chiefs of Staff (JCS) as the provider of long-distance communications service for the DOD.
The DSN is designated as a primary system of communication during peacetime, periods of crisis, preattack, non-nuclear, and post-attack phases of war.

 Database Source Name - Wikipedia, the free encyclopedia
Database Source Names, more commonly seen as the abbreviation, DSN, are data structures used to describe a connection to a database.
Using a DSN to connect to a MySQL database through the Web, Web users can submit form entries to a MySQL database by establishing a connection to the MySQL database's DSN.
The advantage of a DSN is that applications can take advantage of any database, as long as DSN is supported (i.e.

 Voyager - News - Profiles/Features - Deep Space Network
Even though the powerful 20-kilowatt transmitters of the DSN are used to send instruction information to both spacecraft, by the time these signals reach the spacecraft they become very weak.
An analogy of successfully getting a DSN transmitter signal into Voyager-2's limited receiver window, would be like throwing a baseball across thousands of miles of ocean, and being able to get that baseball to pass through a very small port-hole window of a moving cruise ship.
In the future, as these record-breaking distances continue to increase for both of these extreme-distance voyagers, the DSN is planning to implement new techniques to continue to be able to communicate with both spacecraft.

 [No title]
A DSN can be used to notify the sender of a message of any of several conditions: failed delivery, delayed delivery, successful delivery, or the gatewaying of a message into an environment that may not support DSNs.
A DSN contains a set of per-message fields which identify the message and the transaction during which the message was submitted, along with other fields that apply to all delivery attempts described by the DSN.
Its purpose is to allow the sender (or her user agent) to associate the returned DSN with the specific transaction in which the message was sent.

Once you create a DSN for a particular database, you can use the DSN in an application to call information from the database.
DSN is often used by Active Server Pages (ASP) and Visual Basic programs when a query to a database is necessary to retrieve information.
There is also what is known as a "DSN-less connection." Instead of using a DSN to connect to a database, the developer specifies the necessary information right in the application.

The short answer to that question is that the DSN is the largest and most sensitive scientific telecommunications system in the world.
Also among the spacecraft the DSN is currently communicating with are two that it has been talking to the longest.
Later this decade, the first step will be taken in expanding the DSN into space with the launch of a spacecraft to Mars with the sole purpose of being a relay communications satellite like those in orbit around the Earth.

 How to get notified when an e-mail has been read/delivered?
The second problem is addressed by DSN too: you have to specify for each recipient, whether you want a DSN for her.
The relevant RFC for DSN is RFC 1891 K.
Older (outdated?) versions may need a patch for Pine to enable DSN (but it's limited: there is an option in the config screen for delivery SUCCESS notifications).

If you've created a file DSN for a server-based database, you will be prompted with the login dialog box for the database server.
After you have added a data connection to your project, you no longer need the file DSN, because all of the necessary connection information is copied from the file DSN and stored with the Web application in the Global.asa file.
This type of connection, which derives from a DSN but no longer relies upon it, is called a DSN-less connection.

 SitePoint Forums - what DSN   (Site not responding. Last check: 2007-10-20)
DSNs are typically slower and don't gain you anything in the process.
The trouble is they aren't here and I can't tell if it's system or file DSN, and I can't seem to glean from available comments which is preferable.
The only place the DSN comes into play is in the connection string, and I would sincerely hope there'd be a VERY limited amount (ie one method) of connection string assignments.

The DSN is designated as a primary system of communication during peacetime, periods of crisis, preattack, nonnuclear, and post-attack phases of war.
Data processing equipment using DSN voice circuits (dial-up) will use a STU-III or be capable of automatically disconnecting from the access line or interswitch trunk when the transmission is complete or the circuit is preempted.
The DSN may be used to transmit unsecured facsimile traffic without a STU-III only if the facsimile machine or computer transmits within 1 minute after the facsimile transmission ends or the circuit is preempted.

Shortly after sending out the WebWeekly I received a number of emails from readers who had previously read that DSN-less connections were more efficient, and they referenced various Wrox titles as their sources.
I decided that it was time to take advantage of the fact that I am interning at Microsoft, and contacted the gentleman who's presentation was the reference for the performance article on MSDN that I had referenced in the WebWeekly article.
I soon received a reply, informing me that the tests he ran to come to the "System DSN is better" conclusion were run a long time ago, and that they needed to be rerun.

 Four Hundred Guru--Using Different ODBC DSN Types for i5 Access
User DSNs are useful when you want to restrict a connection to a specific user and make it unavailable to any other user who may sign on to the machine.
The other advantage in using File DSNs is that you can email them to other users who can then point their applications at a newly saved File DSN for instant connectivity.
Once you select the DSN category for the Data Source that you are creating, the DSN configuration process is virtually identical for all three categories, with the exception of the naming restriction for File DSNs.

 DSN-Less Database Connection
Normally we would access a database through ODBC and the Data Source Name (DSN) of the database to connect to and issue SQL queries to manipulate the data.
This however, requires a DSN to be configuration on the machine that plans to use the database, which may not be available or convenient.
The access to configure DSNs on a machine may not be an option such as on a remotely hosted web server.
