DNS stands for Domain Name System. It is a system that translates domain names (such as www.seqlogic.com) into IP addresses (such as 192.0.2.1). This allows users to access websites and other resources on the internet using easy-to-remember domain names, rather than having to remember the numerical IP addresses.
The DNS system is distributed, meaning that it is made up of many servers around the world that work together to translate domain names to IP addresses. When a user types a domain name into their web browser, the browser sends a request to a DNS server to resolve the domain name to an IP address. The DNS server then looks up the IP address associated with the domain name and returns it to the browser, which uses the IP address to connect to the correct website or resource.
DNS is a crucial infrastructure component of the internet, as it enables the translation of human-friendly domain names to machine-friendly IP addresses, allowing smooth communication between different devices and networks.
