Dns is a network service on the internet that converts hostnames to IP addresses. This helps users find a website or web page by converting them into IP address. It is one of the basic services that allows millions of people access to the information they require every day.
What is DNS?
The domain name system is an hierarchical database and network service which translates easily memorized domains names into numerical IP addresses required for Internet communication. This is a key part of Internet infrastructure, allowing networks to identify resources such as computers, servers and applications regardless of location.
The Domain Name System is a standardized hierarchical data base that identifies and translates the information elements of domain names into telephone numbers, similar to a phonebook translating a person’s name. The domain system identifies all information elements related to email addresses, radio frequencies identification tags (RFID), universal product codes (UPCs), international characters in host name, and other Internet-identifiers.
A record is an array of data elements specified by the DNS protocol, and stored in zone files. These data are numeric and text-based. They contain different fields for various types of information.
There are five primary record types: A, CNAME, MX, TXT, and SRV. Other types exist, including the ones used to change an IP address for a server or the NS Record that indicates which authoritative servers are responsible for providing information on a domain.
NS records, or named server records, are records that indicate which authoritative name servers have responsibility for the domain. These records can be searched to locate a nameserver. In general, a domain has both a primary and a secondary name server.
DNS resolvers allow you to reach authoritative nameservers for any domain. They maintain all the information about the name and the address of that domain. DNS resolvers query all authoritative names servers, either non-recursively of recursively.
Recursive inquiries are sent by clients to a resolution, which can be a DNS server or local computer. The DNS headers are used to negotiate recursive requests. They indicate whether the request is a nonrecursive one or if recursive. If recursive then they also include the name servers in the recursive.
The recursive queries are compared to a response received from the authoritative DNS server. If the answer is a match, then the recursive query is sent back to the client.
If the match is not found, then the query is sent on to a DNS Recursor. A DNS Recursor is a special server designed for receiving queries from clients via applications like web browsers. The recursor then makes additional requests in order to satisfy the request.
In order to reduce the number of network connections and processing steps required for a DNS resolution, it is first necessary to check the cache in the browser, which contains all the most recent DNS records. This reduces the number and complexity of network connections required to resolve a DNS request. The DNS Recursor then sends a request to an address IP to find the site or page.

What is a "static website"?
A static site is one that stores all content on a server. Visitors can access the website via web browsers.
The term "static” refers the fact that there is no dynamic feature such as changing images or video, animations etc.
This site was initially designed for corporate intranets, but it has been adopted by individuals or small businesses who desire simple websites that don't require complex programming.
Static websites are becoming more popular due to their ease of maintenance. Static sites are easier to maintain and update than fully-featured websites with multiple components (such as blogs).
They also load quicker than their dynamic counterparts. This makes them great for those who have slow Internet connections or users with mobile devices.
Static websites are also more secure than dynamic ones. Static websites are much harder to hack than dynamic ones. Hackers have only access to data stored in a database.
