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

DNS (Domain Name System) is a system that translates human-readable domain names (e.g., example.com) into IP addresses understandable by computers (e.g., 93.184.216.34).

The role of DNS on the internet:

• Allows the use of convenient 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, a request is first sent to a DNS server, which returns the IP address, and then a connection is established with the required server.
