The DNS translates your human-readable address into an IP number.
True
Yes, that is correct. The Domain Name System (DNS) is responsible for translating human-readable domain names (such as www.example.com) into their corresponding IP addresses (such as 192.168.1.1). This translation is necessary because computers communicate with each other through IP addresses, which are numerical identifiers assigned to each device on a network.
When you type a URL into your web browser, it sends a request to a DNS resolver to find the corresponding IP address for that domain name. The resolver then queries the DNS hierarchy to find the IP address for that domain name, starting from the root of the DNS hierarchy and descending through a series of authoritative name servers until it finds the IP address it needs.
Once the resolver has obtained the IP address, it caches it locally in case it needs to look it up again in the future. This allows subsequent requests to be resolved more quickly, as the resolver can skip the recursive lookup process and use the cached information instead.
Overall, the DNS plays a critical role in enabling communication between devices on the internet, as it allows us to use human-readable domain names instead of having to remember and enter IP addresses directly.
