Caching only DNS servers is a computer that either has MS Windows Sever 2000, 2003 or 2008 operating system installed on it. Then it has a DNS server role installed on it (think of it as a plug-in program like ad-blocker for Firefox). And instead of having a DNS zone (sort of like a shard network folder that only other severs which have been giving permission to access the folder can have a copy of it, and inside are the names address of all the other computers like the white pages) configured into it, it instead remembers where everyone has been so that it takes less time for the next time someone else wants to go to the same place. only problem is that the computer can never shutdown. Think of it like a word document in progress that can be changed and read but the save button is missing so in the event of a power faller all information will be lost. However it doesn't need to be managed like DNS zone.

What is the purpose of caching in DNS?
When the web browser wants to load a web page, it needs to contact a DNS server first, which will translate the URL address into a machine readable format - the IP address. Even though the translation takes only a few hundred milliseconds each time a message is sent, these can add up over time, as the number of requests can easily reach hundreds or thousands of DNS queries. DNS servers can sometimes be unavailable and the responses to queries can be very slow. To speed up this process is to cache the information locally thereby eliminating the need for repetitive queries to the remote DNS server. This is done by telling PostCast Server to contact a local database on your computer, rather than the remote DNS server. This local connection can be performed much faster and does not depend on the response time of the remote DNS server across the Internet. PostCast Server contacts the remote DNS server once, and then caches (memorizes) the addresses returned from the query. So the next time you are requesting the same domain.com address, it instantly returns the answer, without having to contact your ISP's DNS server to ask it for the translation. The process is much faster, since it does not have to connect to any remote servers every time. Basically, the logic behind the DNS cache feature is to include both bad and good domains in the list and use the "Valid" column to mark them as valid. The domain is considered bad only if DNS server returns the "Unresolved" error, which means that the DNS entry for that domain does not exist.

How DNS server caching works?
If a client send a query requesting for a particular web page to the DNS server and if the DNS server resolves the page from the other DNS servers & it will be store the same page in the DNS cache and it will give the response to the client with the requested page. If again the same web page is requested by any client then DNS server will get the web page from the DNS cache instead of again fetching the same page from the internet. With this there wont be any delay for the client to get the web page. This helps in bandwidth control. This is how the DNS server caching works.
Which two tasks are the responsibility of the local DNS server?

When would a dns server contact a root server?
