Domain (domain name) - is a readable textual logical identifier used to identify a resource on the Internet, such as a website, email, or other services. Domains are used to replace numerical IP addresses that actually point to specific servers on the Internet.
In simpler terms - it is the name of the site (the site address) that a user types in the browser's address bar. The domain name of this site is tseivo.com

The domain consists of two main parts: second level (Second-Level Domain, SLD) and top level (Top-Level Domain, TLD). For example, in the domain "tseivo.com," "tseivo" is the second level, and "com" is the top level.
Domains are used so that people can easily remember and refer to resources on the Internet using a textual identifier instead of a numerical IP address. Domain registration is conducted through domain registrars, who obtain permission to use a specific domain for a certain period of time.
