The difference between root servers and root domain name servers

Root servers store the Internet's root zone (all top-level domain name TLDs), while root name servers store root zone information (containing all TLDs and their corresponding authoritative name server information). The number of root servers is 13, distributed around the world, and the number of root domain name servers is unlimited. Root servers determine which TLD's name servers to query, while root name servers provide information about the TLD's name servers.
