Exploring DNS (Domain Name System)
1. What is DNS?
The Domain Name System (DNS) is a fundamental technology that translates human-readable domain names into IP addresses. When you enter a website’s URL in your browser, the DNS comes into play, allowing your computer to locate the website’s server on the internet. It acts as a phonebook of the internet, enabling smooth and efficient communication between devices.
2. How DNS Works
DNS operates through a hierarchical and distributed database. When you enter a URL, your computer first checks its local DNS cache to see if the domain name is already resolved. If not, it sends a request to the recursive DNS resolver, which then communicates with authoritative DNS servers to obtain the corresponding IP address.
3. The Importance of DNS
DNS is a critical component of the internet infrastructure. Without DNS, users would have to memorize IP addresses to access websites, which is both impractical and inconvenient. The efficient functioning of DNS ensures faster and reliable internet access.
