What server is used to convert domain names to IP addresses in order to ease online browsing or the location of a directory resource on the network?

When a user enters www.sybex.com into a web browser, the Domain Name System (DNS) server converts the domain name into an IP address. Similarly, DNS servers will resolve a fully qualified domain name (FQDN) network directory resource on the network to allow for its location. Syslog servers keep track of network events to help with network management. Print servers offer and manage access to one or more printers by numerous network users, whereas an authentication server checks identity before allowing access to network resources.
