What is the role of the Domain Name System (DNS) in internet infrastructure?

Detailed Solution: Question 1

The Domain Name System (DNS) plays a crucial role in the internet's infrastructure by translating human-readable domain names into numerical IP addresses that computers use to communicate with each other. When you enter a URL into your web browser, the DNS server helps to find the corresponding IP address of the web server hosting the requested content, enabling seamless access to websites and online services.

What role do IP addresses play in device communication on networks?

Detailed Solution: Question 2

IP addresses play a crucial role in device communication on networks by enabling devices to communicate with each other over a network. Each device is assigned a unique IP address, which acts as a numerical label that facilitates the routing of data packets between devices on the same network or across different networks. IP addresses ensure that data is sent to the correct destination, allowing devices to interact and exchange information effectively.

What happens if a DNS server cannot find the IP address for a given domain name?

Detailed Solution: Question 4

If a DNS server cannot find the IP address for a specific domain name, it will forward the request to a higher-level DNS server for resolution. This hierarchical system ensures that even if one DNS server fails to find the IP address, the request can be escalated to other servers in the network until the correct IP address is retrieved, helping users access the requested web content efficiently.
