An A record maps a name (e.g. codeproject.com or maps.google.com) to a static IP address (that is, in most cases, the public IP of the server hosting the website).
The nameservers (or primary and secondary DNS servers) are the IP addresses or names of the servers that are autoritative for a specific domain, for example yourwebsite.com. They basically know the IP address of the server yourwebsite.com is hosted at. For each second-level domain name (codeproject.com, google.com, etc.) two DNS servers must be recorded in the TLD registry (.com, .org, .de, .it, etc.).
DNS is not exactly simple, so I'd suggest you to get some info before changing anything. Here is a start: Wikipedia[^].
EDIT: there are also other types of records, most notably MX. If you change the nameservers, you'll also have to re-configure all the records, as you're actually discarding the old DNS server for a new one (well, two).

yeah that helps
so does it works like
when we type http://www.codeproject.com
appropriate dns servers assigned for codeproject.com look for the IP address of the hosting computer using the A Record and if they can resolve the ip address, we get web page or some error (e.g DNS Server could not resolve the Hosting Server)
and
if we send email to support@codeproject.com
Domain Name Server looks for MX Record to find out the Mail Server
So it seems Changing DNS Server for a Domain is only one part of Changing Hosting
We will need to change all the A, MX etc Records as well
Did i got it correct?

Yes. I suggest to print/copy/save the current DNS configuration so you can re-create it on the new nameserver (with new IP addresses I guess). MX records have an important role as they do not point to the webserver but to the SMTP server for your domain, which is usually handled by the hosting provider. Make sure you check with their support before proceeding.

yeah thanks, will do.
The Only concern is that all Hosting Providers ask to change only nameserver and they do not talk of changing A record etc.
http://support.netfirms.com/article.php?id=032[^]
Netfirms tells all about all hosting providers and all they ask is to change the NameServer.
Will Update here after doing the changes.

They want you to change to their name servers; at which point a tech runs a script and all the needed records are created. Much easier for them; and for 99% of users as well.

In England a git is a person of absolutely no worth. I hope your version is not made in that image.

To Hell with the US economy, it's the European and Chinese economies that matter.
We've had enough of the world being f***ed up by people who just want to get rich quick; it's time for that power to be taken back into the hands of the grown-ups.
