To resolve host names to IP address eg wiki.answers.com to 192.41.64.63 or YourComputerName to 192.168.1.XX
If it wasnt for this to access a website you would need to type the IP address of the site or to access a share on a computer in stead of typing \\computername you would need to type the computer IP
DNS also does the opposite IP to Hostname so you can do a lookup on an IP address and find out the hostname
for example if you go in to command promt and do tracert yourcompIP it will say tracing route of YourCOmputer Name [YourCOmputerIP]

The primary DNS server is usually the same as the router's IP adress.
If a DNS server cannot find the answer to the DNS Query in its own database it will first query the forwarders (if there are any configured) and then ask the root server. root servers (by default) are the master DNS servers of the Internet.
The prefered DNS server for the site is the server which sends the dns zone updates to all the other servers in the site. The primary DNS zone is created on the server and it has the authority to send changes in zone to other servers
The network operating system that one is working with will determine the specific information an individual searches for when looking for information on a DNS (Domain Name Service) server. One can learn from books at their local book store or library about DNS on Windows and Linux NOS's, or one could go to their local community college and take a basic Networking class to learn what a DNS server is.
