A domain name is your website's unique address on the internet, like www.yourbusiness.com. It's how users find you online instead of typing complex numerical IP addresses. Think of it as your digital street address.

Every domain consists of two main parts:

• Second-Level Domain (SLD): This is your chosen name (e.g., "yourbusiness").
• Top-Level Domain (TLD): The extension following the dot, like .com, .net, .org, or country codes like .uk.

To use a domain, you must register it through a domain registrar, typically for an annual fee. Registration gives you exclusive rights to that name for the period you've paid. It's crucial to choose a name that is:

• Memorable and easy to spell.
• Relevant to your brand or content.
• Short to minimize typing errors.

Once registered, you point your domain to your web hosting server via DNS (Domain Name System) settings. This connects your address to your website's files, making it live. Remember, a domain is separate from hosting; one is the address, the other is the land and house. For a professional online presence, you need both.

Keep your domain registration renewed to avoid losing it. Consider privacy protection to hide your personal contact information in public WHOIS databases. A strong domain is the foundation of your online identity.
