Domain Name System.
On the Internet, the Domain Name System (DNS) associates various sorts of information with so-called domain names; most importantly, it serves as the "phone book" for the Internet: it translates human-readable computer hostnames, e.g. en.wikipedia.org, into the IP addresses that networking equipment needs for delivering information. It also stores other information such as the list of mail exchange servers that accept email for a given domain. In providing a worldwide keyword-based redirection service, the Domain Name System is an essential component of contemporary Internet use.
The most basic use of DNS is to translate hostnames to IP addresses. It is in very simple terms like a phone book. For example, if you want to know the internet address of en.wikipedia.org, the Domain Name System can be used to tell you it is 66.230.200.100. DNS also has other important uses.
Pre-eminently, DNS makes it possible to assign Internet destinations to the human organization or concern they represent, independently of the physical routing hierarchy represented by the numerical IP address. Because of this, hyperlinks and Internet contact information can remain the same, whatever the current IP routing arrangements may be, and can take a human-readable form (such as "wikipedia.org") which is rather easier to remember than an IP address (such as 66.230.200.100). People take advantage of this when they recite meaningful URLs and e-mail addresses without caring how the machine will actually locate them.
The Domain Name System distributes the responsibility for assigning domain names and mapping them to IP networks by allowing an authoritative server for each domain to keep track of its own changes, avoiding the need for a central registrar to be continually consulted and updated.

Domain Name System (DNS) associates various sorts of information with so-called domain names; most importantly, it serves as the directory for the Internet: converts computer hostnames into the IP addresses that networking equipment needs for delivering information. It is also a storage area for other information such as the list of mail exchange servers that accept email for a given domain. The Domain Name System (DNS) is an important component of the World Wide Web.
When it comes to your second question can you state what is there to fix? or what is your problem with your DNS

You're having a DNS error message when you try to access something on the Internet. DNS=Domain Name Server.
A domain name (like 'www.yahoo.com') is associated with an IP address (like '123.123.123.123'). Somehow you have lost the connection to your DNS servers and you aren't getting that name-number association.
To fix this, you can do several things.
1) refresh your network settings (as described above)
2) Manually assign your DNS servers in your network card settings (under TCP/IP settings)
3) Add an entry in your hosts file and manually assign the domain name to the IP address.
This error can mean that the servers you are using are temporarily down. Sometimes, your router acts as a proxy to your DNS server and can fail. I recommend changing that so your router isn't a proxy to real DNS servers.
If you need help with any of this, email me.

DNS means Domain Name System..It is in very simple terms like a phone book. For example, if you want to know the internet address of yahoo.com , the Domain Name System can be used to tell you it is something like 66.230.200.100. DNS also has other important uses.
You dont fix it .. But what you do to view your website is for you to "Point" your Domain to the DNS. Your Domain Name resides in your registrar while your DNS resides in your Hosting where your website is stored. You have to ask your Hosting what their Nameservers are...
Hope this helps!

Did you try troubleshooting your internet connection and it said DNS error? If so, all you have to do is disconnect, then reconnect to the internet. On a cable modem you unplug it and plug it back in.
I guess DNS does stand for Domain Name System. I was taught that it meant Domain Name Server, though. Could be either way I guess.

DNS= Domain name server.. it is what streams your connection to you over the net/isp
every time you turn off your connection and turn it on your dns issues you another ip address.. if you want to "fix" your dns you need to call up your internet provider and ask them what other dns features can you have applied onto your account.. you cant really fix your dns.. the server can..
or be more specific of what your problem is an i can see if i can help..

DNS stands for Domain Naming System and it is used to locate an IP address that corresponds to a certain name. For example typing in www.microsoft.com will cause you to query DNS to return the actual IP address of the site which will allow your computer to attach to the site.

DNS as other said is Domain Name Server... Computers don't recognize names they recognize numbers. When you put in a name like yahoo.com into your address line, the internet takes you to a domain name server and that looks up what is called the ip (internet protocol) address for yahoo. like... 215.22.55.222. Then thru a series of high speed switches called routers you are connected to 215.22.55.222 which is the yahoo server (i made up the numbers).
Why not just put in 215.22.55.222 and connect directly.. Well you can but humans cant remember number sequences as well as names.. So the name servers act as a way of looking up the ip address so you dont have to remember all those numbers.
Taking it to the next step to clarify... computers don't recognize decimal numbers like 215.22.55.222 either. They have to convert that into binary numbers 1's and 0's, like
010001101101 etc... When it gets to the core thats all a computer can recognize.

DNS is Domain Network Server, the machines that map a URL such as yahoo.com into an IP address such as 123.23.45.45. You don't fix it; the keepers of the network addresses do. Your only interaction with the system (other than to use it) is to tell the DNS system what the IP address of the server is on which you have your Web pages.
