Online storage, often called web hosting storage or disk space, is the digital space on a server where all your website's files, data, and content are stored and made accessible on the internet. Think of it as the hard drive for your website.

When you purchase a hosting plan, you are essentially renting a portion of a powerful, always-on computer (a server). All your website's components—HTML files, images, videos, code, and databases—reside in this allocated online storage. Key points include:

• Measurement: Storage is measured in gigabytes (GB) or terabytes (TB).
• Content: It holds everything from your site's text and design to user uploads and email data.
• Access: Visitors access these stored files through their web browsers when they type your domain name.

Choosing the right amount is crucial. Too little storage can cause your site to run out of space and crash, while too much means you're paying for resources you don't use. For most small business or personal sites, plans offering 10-50GB are a great start. Always consider future growth and the type of content you'll host—high-resolution images and videos consume space much faster.

In summary, online storage is the foundational real estate of your website. Selecting a reliable hosting provider with adequate, fast, and secure storage ensures your site remains online, loads quickly, and scales with your needs.
