Domain name
A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a website, or the web site itself or any other service communicated via the Internet.
What is DNS server is
A DNS server, or Domain Name System server, is a server responsible for translating human-readable domain names into IP addresses that computers can understand. When you enter a URL into your web browser, your computer queries a DNS server to retrieve the IP address associated with that domain name, allowing you to connect to the website. DNS servers are a critical component of the Internet infrastructure and are used constantly by users all around the world.
What is the structure of a domain
The structure of a domain typically consists of two or more parts separated by dots. The rightmost part is the top-level domain (TLD), such as .com or .org, and the leftmost part specifies the name of the domain itself. For example, in the domain name "example.com", ".com" is the TLD and "example" is the domain name. Domains can also have subdomains, which are additional parts added to the left of the domain name, separated by dots. For example, "subdomain.example.com" is a subdomain of "example.com".
URL
A URL (Uniform Resource Locator) consists of several parts. The first part is the protocol, which indicates the type of connection being made, such as HTTP or HTTPS. The second part is the domain name, which identifies the specific website being accessed. The third part is the path, which indicates the specific page or resource being requested on that website. Optional parts of a URL include a port number, which specifies a specific network port to use for the connection, and query parameters, which can be used to pass additional information to the website. Overall, a URL is used to uniquely identify a specific resource on the Internet and specify how to access it.
What is TLD
A top-level domain (TLD) is the last segment of a domain name, following the final dot. Some of the most common TLDs include:
- .com (commercial)
- .org (organization)
- .net (network)
- .gov (government)
- .edu (education)
- .mil (military)
These are just a few examples; there are many other TLDs in use today.
