hey guys .
i read some description about NS record . but i can't understand why use NS (Name Server) record in zone files ? and what exactly is the task.

As you know, NS = Name server records, so if you query a name server for the NS record for a domain, it will return ALL the name servers which can serve that domain, so other name servers can be provided as well as the one you are currently querying. If you have a scenario where you use a simple domain registrar that do NOT provide domain management, they will only host DNS for the NS records, and you provide the registrar with the appropriate NS records for your DNS service, which is nothing to do with the registration of the domain.
