Domain Name Explained in Simple Terms

A domain name is a unique address that identifies a website on the internet. It’s essentially the website’s “name” that users type into their browser’s address bar to access the site. In this article, we’ll dive into what a domain name is, how it works, and why it’s important for web hosting.

A domain name is made up of two parts: the actual name (such as “google”) and the top-level domain (such as “.com”). When a user types in a domain name, their computer contacts a domain name system (DNS) server that translates the name into an IP address, which is used to locate the website’s server and retrieve its content.

Domain names are important for web hosting because they provide an easy-to-remember and recognizable way for users to access a website. They also allow website owners to brand their site with a unique and memorable name, and can even have an impact on search engine optimization (SEO) and website traffic.
