Verkkotunnukset

Verkkotunnukset, often referred to as domain names, are unique and memorable addresses used to access websites on the internet. They are essentially the human-readable equivalents of numerical IP addresses, which computers use to identify each other. A verkkotunnus consists of two main parts: a name and a domain extension, also known as a top-level domain (TLD). For example, in "example.com", "example" is the name and ".com" is the TLD.

The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or any resource connected to the Internet or a private network. It translates human-friendly verkkotunnukset into machine-readable IP addresses. When you type a verkkotunnus into your web browser, your computer queries DNS servers to find the corresponding IP address, which then allows your browser to connect to the correct server and display the website.

Verkkotunnukset are registered through domain registrars, which are accredited companies authorized to sell domain names. The registration process involves choosing an available verkkotunnus, providing contact information, and paying an annual fee. Owning a verkkotunnus gives individuals and organizations exclusive rights to use that specific address for a set period. Different TLDs exist, such as .com, .org, .net, and country-code TLDs like .fi for Finland. The choice of TLD can influence the perceived purpose and geographic relevance of a website.
