A website works worldwide by using the Internet and a combination of technologies that allow users to access it from anywhere. Here’s how it works step by step:
1. Website Development
- Websites are created using HTML, CSS, and JavaScript for design and functionality.
- Advanced websites use backend technologies like PHP, Python, Node.js, or databases like MySQL.
2. Hosting the Website
- A website needs to be stored on a server (a computer that runs 24/7).
- Hosting providers like GoDaddy, Bluehost, AWS, and Google Cloud provide server space.
3. Domain Name System (DNS)
- Every website has an IP address (e.g., 192.168.1.1), but users access websites using domain names (e.g., www.example.com).
- The DNS translates domain names into IP addresses so that browsers can find the website.
4. How Users Access the Website
- When a user types a website URL in a browser:
- The browser contacts a DNS server to find the website’s IP.
- The request is sent to the hosting server.
- The server sends back the website’s files (HTML, images, CSS, JS).
- The browser renders the website for the user.
5. Global Access
- Websites work worldwide because:
- The internet connects devices globally.
- Servers are distributed worldwide using CDNs (Content Delivery Networks) to speed up loading.
- Hosting providers have data centers in different countries for better performance.
6. Security & Speed
- SSL (Secure Sockets Layer) ensures secure data transfer (HTTPS).
- CDN (Content Delivery Network) helps load websites faster from different locations.
- Caching improves website speed by storing copies of files closer to users.
