Primary and Secondary DNS Servers are used to ensure the availability and reliability of domain name resolution services. The primary server holds the original read-write copy of the DNS records, while secondary servers hold read-only copies to provide redundancy and load balancing.

DNS records are essential components of the Domain Name System that store information about domain names, translating human-readable addresses into IP addresses necessary for locating devices on a network. They enable the functioning of the internet by directing traffic to the correct servers, ensuring that users can access websites and services efficiently.

Redundancy refers to the inclusion of extra components or information that are not strictly necessary, often to ensure reliability and fault tolerance. It is a crucial concept in various fields, from engineering and computing to linguistics and organizational design, where it helps prevent system failures and enhances communication clarity.

Load balancing is a method used to distribute network or application traffic across multiple servers to ensure no single server becomes overwhelmed, thereby improving responsiveness and availability. It is critical for optimizing resource use, maximizing throughput, and minimizing response time in distributed computing environments.
