Practical explanation:
When someone types a website address into a browser, DNS helps direct that request to the right server. Without DNS, users would need to remember numeric server addresses instead of simple, readable domain names.
How it works:
DNS relies on a network of servers that respond to requests by matching domain names with their assigned server locations. This process happens automatically and usually takes only a fraction of a second.
Why it matters:
DNS plays a key role in website availability and performance. Incorrect DNS settings can prevent a website from loading or cause delays when accessing it.
When to use it:
DNS is involved whenever a domain is connected to hosting, email services are set up, or a website is moved to a different server.
