A subdomain is the part of the web address that's before a domain and you have probably seen a lot of subdomains while browsing the Internet. As an illustration, many websites such as Wikipedia have versions in various languages using subdomains - en.wikipedia.org, de.wikipedia.org and so on. The advantage of using a subdomain is that it can have an independent website and its own records, so you are able to even host it on another server. The practical use is that you can have a supplementary website, such as an e-learning portal for students on top of the primary school site. If you work with subdomains rather than subfolders, it's going to be much easier to perform maintenance or to upgrade a certain website, not mentioning that it's going to be more secure to have the websites separate from one another.
Subdomains in Shared Web Hosting
When you use shared web hosting plans you'll be able to create subdomains with only a few mouse clicks in your hosting Control Panel. All of them are going to be listed in one location together with the domains hosted in the account and arranged under their own domain to help make their managing easier. Whatever the plan that you choose, you are going to be able to create numerous subdomains and set their access folder or set up custom error pages along the way. You will also have access to a lot of functions for any of them with just a click, so from the same section where you create them you can access their DNS records, files, visitor statistics, etc. As opposed to other providers, we haven't limited the number of subdomains you can have even if you host only one domain within the account.
