Introduction to System (DNS) Administration

As technology continues to advance, businesses are becoming increasingly reliant on their network infrastructure. A well-functioning network is crucial for seamless communication, efficient operations, and optimal productivity. One of the key components of a network is the Domain Name System (DNS). DNS plays a vital role in translating domain names into IP addresses, allowing devices to communicate with each other over the internet. In this article, I will explore the importance of system (DNS) administration in enhancing network performance and the various aspects associated with it.

The role of DNS in network performance

DNS acts as a directory service for the internet, translating human-friendly domain names into machine-readable IP addresses.
