In the context of web hosting and internet domains, a domain and a subdomain are related but distinct concepts.
A domain is a unique name that identifies a website or a server on the internet. It consists of two parts: the top-level domain (TLD), which is the part of the domain name that comes after the last dot, such as .com, .org, or .net; and the second-level domain (SLD), which is the part of the domain name that comes before the TLD, such as google, amazon, or wikipedia.
A subdomain, on the other hand, is a subcategory or subdivision of a larger domain. It is essentially a prefix to the main domain name, separated by a dot. For example, in the domain name blog.example.com, "blog" is the subdomain, "example" is the SLD, and "com" is the TLD. A subdomain can have its own separate content, such as a separate website, a blog, or a specific section of a larger website.
In summary, a domain is a unique name that identifies a website or a server on the internet, while a subdomain is a subdivision of a larger domain that can have its own separate content.
