Web hosting is a service that allows individuals and organizations to make their websites accessible via the internet. When you create a website, it consists of various files, such as HTML, CSS, images, and scripts, that need to be stored somewhere so that people can access them online. Web hosting providers offer the technology and services needed to store these files on their servers and make your website available to visitors.
How Web Hosting Works
1. Choosing a Web Hosting Provider
- You begin by selecting a web hosting provider that suits your needs. There are many types of hosting services, such as shared hosting, VPS hosting, dedicated hosting, and cloud hosting, each offering different levels of performance, storage, and control.
2. Purchasing a Domain Name
- A domain name is your website’s address on the internet (e.g., www.example.com). Some web hosting providers offer domain registration services, or you can purchase a domain separately and link it to your hosting account.
3. Storing Website Files
- Once you have a hosting account, you upload your website files to the server provided by the hosting company. This can be done using an FTP client or through the hosting provider’s control panel.
4. Setting Up Your Website
- Configure your website settings, such as installing content management systems (CMS) like WordPress, setting up databases, and configuring email accounts. Most hosting providers offer user-friendly control panels (like cPanel or Plesk) to manage these settings.
5. DNS Configuration
- The Domain Name System (DNS) translates your domain name into the IP address of the server where your website files are stored. You need to configure your domain’s DNS settings to point to your hosting provider’s servers.
6. Website Accessibility
- Once everything is set up, your website becomes accessible to the public. When someone types your domain name into their web browser, the browser sends a request to your hosting provider’s server to fetch the website files and display them to the user.
