Resolvers

10 Nov

Today as usual i start to surf on net ,by the way i found this term “resolver” and i go through in detail about it.In this post i shared some intro about it.

Resolvers are the interface to user program to domain servers.In simple, it receives request from user program and returns desired information in a form compatible with the local host’s data formats.It will  located on same machine but it needs to consult with name servers on other hosts.this will take little amount of time.

Important goal of resolver is to eliminate network delay and name server load from most requests by answering them from its cache of prior results. It follows that caches which are shared by multiple processes, users, machines, etc., are more efficient than non-shared caches.

I hope you may got small info about this resolver in this post.
