When starting an online project, three terms often cause confusion: domain, website, and web server. Although they work together, each represents a different part of your online presence.

Domain
A domain is the address people type into their browser to reach a website - for example, google.com, mybox.com, or yourbusiness.ro.
A domain is registered through a domain registrar and must be renewed periodically. It connects to a server using DNS (Domain Name System), which translates the domain name into a server’s IP address.
Without hosting, a domain does nothing on its own - it is simply a name that points to a location on the internet.
Website
A website is the content people see and interact with online - pages, images, text, forms, and applications such as an e-commerce store, blog, or portfolio.
A website is made of files: HTML, CSS, JavaScript, images, and databases. Those files must be stored on a server to be accessible.
Web server
A web server is the computer that stores your website files and delivers them to visitors. When someone types your domain into a browser, DNS resolves the domain to an IP address, the server receives the request, and sends back the website files for the browser to display.
Servers come in different forms - shared hosting, VPS, dedicated, or cloud - each suited to different project sizes and requirements.
How they work together
| Role | Without it | |
| Domain | Your online address | Visitors have no way to find your site |
| Website | Your content | There is nothing to display |
| Web server | Stores and delivers your content | Files have nowhere to live |
All three are required. Without any one of them, your online presence does not function
