Can you explain what the DNS system is and what role it plays on the internet?

DNS (Domain Name System) is a system that translates human-readable domain names (e.g., example.com) into IP addresses (e.g., 93.184.216.34), which are used for routing on the internet.

Role of DNS:

• Allows users to use understandable names instead of numeric addresses.
• Provides a distributed and scalable way to find addresses.
• Speeds up access to resources through caching.

When you enter a website address in a browser, the request first goes to a DNS server, which returns the IP, after which a connection is established with the required server.
