Hosting is a service that allows individuals and organizations to make their website accessible on the internet. When you buy a hosting plan, you're essentially renting digital space on a server. This server is a powerful computer that stores all the files, data, and code that make up your website. It's connected to the internet 24/7, so when someone types your website's domain name into their browser, the server sends those files to their computer, displaying your site. Think of it as renting a plot of land to build a house; the hosting provider owns the land (the server) and gives you a space to build your online presence. Without hosting, your website would only exist on your personal computer.
Hosting lets individuals or organizations rent server space so their website is accessible on the internet 24/7. The hosting provider owns the server, you build your site on it; without hosting, your site can't be publicly reachable.
