Common Website Terminology

A domain name is the address where users can access a website. It is the unique name that appears after "www" in web addresses. For example, in www.mediakular.com, "mediakular.com" is the domain name.

You can register domain names with so called Domain Registrars. Some of the most popular ones are NameCheap, GoDaddy, IONOS and Google Domains. Here you can find a List of The Best Domain Registrars Of 2024 on Forbes.

2. URL (Uniform Resource Locator)

A URL is the web address of a specific page or file on the internet. It typically consists of the domain name along with additional path information.

For example


would be a URL consisting of "http" as a protocol, "www.mywebsite.com" as hostname and "index.html" as the file name.

3. HTML (Hypertext Markup Language)

HTML is the standard language used to create web pages. It structures content on the web by using elements such as headings, paragraphs, links, and images.

6. Responsive Design

Responsive design refers to a web design approach that ensures a website looks good and functions well on a variety of devices, including desktops, tablets, and smartphones. Often people also talk about "Mobile optimization", which means in most cases the same, even if the name does not include other devices than mobile phones.

12. UI (User Interface)

The UI is the visual part of a website or application that users interact with. It includes buttons, forms, menus, and other elements. If a user browses for new shoes on a website, they are using the User Interface to do so. The User interface is always an important part of a Front-End.
