A domain name is a unique address that identifies your website on the internet (e.g., www.yoursite.com). It’s necessary because it serves as an easy-to-remember identifier for your website, making it accessible to users. Instead of having to remember a long string of numbers (IP address), a domain name allows users to quickly find your site, giving your business or personal brand a professional online presence.

Top-Level Domains (TLDs) are the suffixes at the end of a domain name (like .com, .org, or .net). Some of the most popular and affordable TLDs include:

.com: The most recognized and widely used, suitable for businesses, blogs, and personal websites.
.net: Often used for technology-focused sites or businesses.
.org: Commonly used by non-profit organizations.
.co: A trendy alternative to .com, often used by startups or tech companies.
.io: Popular in the tech and startup community, especially for software and digital companies.
These TLDs are not only widely recognized but also generally affordable.

To check if a domain is available, you can use a domain search tool. Most domain registrars have a search bar on their websites where you can type in your desired domain name. The tool will let you know if the domain is available or already taken. If it’s unavailable, it may suggest alternative names or TLDs.
