Domain
A domain is a key component of the Internet’s Domain Name System (DNS), which helps connect Internet resources and computers by their names. This system converts a domain name into an IP address, allowing computers and servers to find each other. Domains are hierarchically structured, starting with high-level domains (TLDs) such as “.com”, “.org”, “.net”, “.edu”, etc. domains. These are widely known and generic domains used to identify websites and other Internet resources. Each domain ends with a TLD indicating its origin or type, such as “.com” for businesses or “.edu” for educational institutions.
A domain name, which is part of a domain, is a human-readable identifier that directs to an internet resource such as a website or an email server. For example, “example.com” could be a domain name that points to a website or service operated by a company called “Example”. Sometimes a company may decide to register only a subdomain, such as “designweb.ee”, without a main domain, such as “example.com”. This may be useful for branding purposes or to obtain a short domain name.
The subdomain
A subdomain is the part of a domain that is higher up in the domain name hierarchy. It is like a branch of the root domain, allowing organisations to create subdivisions of their root domain. As an example, if the DisainVeeb company wants to create different parts of their website separately, they can create subdomains such as “blog.designveeb.ee”, “portfoolio.designveeb.ee”, “services.designveeb.ee”, etc. These sub-domains allow a company to structure its website according to different themes or services. The different subdomains allow the provision of specific content and services on separate web pages, thereby improving the user experience and navigation.
The creation of a subdomain usually requires the registration of a new domain name, but they can be very useful for organisations looking to structure and categorise their online resources. In addition, sub-domains allow for better control over websites and services and contribute to a better user experience and navigation.
Optimisation for mobile
In addition to domain and subdomain structures, optimising websites for mobile devices is also important on today’s web. More and more people are browsing the internet on mobile devices. Mobile optimisation ensures that a website loads quickly, text is readable and navigation is easy on mobile devices.
Summary
In summary, domains and sub-domains are an important means of identifying the internet and structuring an organisation’s online resources. Mobile optimisation helps to ensure that websites are user-friendly and convenient on all types of devices.
