The main purpose of a DNS server (Domain Name System) is to translate user-friendly domain names into IP addresses, enabling browsers to locate and access websites. This system is essential for the functioning of the internet, as it simplifies the process of navigating online. Without DNS servers, users would need to remember complex numerical IP addresses instead of easy-to-remember domain names. Besides basic translation, DNS servers can provide caching to reduce latency and improve speed, contributing to a more efficient browsing experience and helping to distribute and balance traffic across various servers.
