full details about the domain

 

What is domain ?

A domain is the human-readable address of a website.

• Example:
  In the URL https://www.example.com, the domain is example.com.

·         Example:
Instead of typing 172.217.3.110, you type google.com.                                  

·           It acts as a unique identifier for a specific website or online resource,         allowing users to easily navigate the web by typing or clicking on familiar    names. 

 Structure of a Domain Name

·         A domain is usually made up of three parts, separated by dots:

·              │     │    └── Top-Level Domain (TLD) → e.g., .com, .org, .net

·              │     └───── Second-Level Domain (SLD) → "example"

·              └──────────── Subdomain → "www" (optional)

 

 Types of Domains

• Top-Level Domains (TLDs):

o    Generic: .com, .org, .net

o    Country code: .uk, .jp, .in

o    Newer TLDs: .tech, .store, .ai

• Second-Level Domain (SLD):

o    This is the name you choose when registering a domain (e.g., openai in openai.com).

• Subdomains:

o    A prefix to the main domain, used to organize sections.

§  Example: blog.example.com or support.google.com

 

 Domain Registration

To use a domain, you must register it through a domain registrar (e.g., GoDaddy, Namecheap, Google Domains).

• Domains are rented, not owned — usually for 1–10 years.
• You can check if a domain is available using WHOIS tools or registrar websites.

 

Why Domains Matter

• They make the internet user-friendly.
• Domains are linked to websites, emails, online businesses, and branding.
