Purpose of DNS and how it works within a Windows environment.

The Domain Name System (DNS) is a critical component of any network infrastructure, as it translates human-readable domain names into IP addresses that computers can understand. 

This process allows users to access resources on the network using easily memorable names instead of numerical IP addresses.

Within a Windows environment, DNS integrates seamlessly with Active Directory, enabling efficient management and organization of network resources. 

The Windows DNS server stores resource records for each domain name in its database, which are then used to resolve queries from clients. 

When a client requests a specific domain name, the DNS server searches its database for the corresponding IP address and returns it to the client.

If the requested domain name isn’t found locally, the DNS server forwards the query to other DNS servers until the correct IP address is obtained. 

This hierarchical structure ensures fast and accurate resolution of domain names, ultimately enhancing user experience and overall network performance.
