The infrastructure of a website encompasses the range of systems, services, and tools that together enable a website to be available to its users. It forms the backbone of a website's operations and influences aspects like speed, reliability, security, and scalability. Here are the elements that constitute a website's infrastructure:

Domain Name System (DNS)

Domain Name System (DNS) is a hierarchical and decentralized system designed to translate human-readable domain names, such as "www.example.com", into IP addresses, which are numerical labels, enabling computers to identify each other on the Internet or a private network. The DNS system is one of the foundational elements of the modern internet.

• Domain Name: It's the human-readable address (URL) of a website, like www.example.com. It's easier to remember than IP addresses.
• Domain Registrar: Companies like GoDaddy, Namecheap, and Bluehost, where you can register a domain name.
• DNS Hosting Services: Maintain the directory of domain names and translate them to IP addresses, ensuring that when someone enters a domain, they're directed to the correct server.
