What exactly is a subdomain?

[hernandez9039]

A subdomain name would be a "name *under* your domain name", something like "subdomain.yourdomain.com".

Hi everyone,
2. A subdomain is served out of a folder in your web root.

Not necessarily. It depends on how your subdomain is configured. For example, your domain name is 'lydia09.com' and you wanted to create say a subdomain named 'forums'. cPanel by default creates a folder on your server root named what ever your subdomain name is. so it's gonna be 'forums.lydia09.com' and the folder 'forums' is gonna be at your root which basically means you can also access 'forums.lydia09.com' at 'lydia09.com/forums'. That is IF you left the settings at subdomain creation. It can also be served outside the 'public_html' folder say your root folder. It will be accessible yes but only from 'forums.lydia09.com'

3. A subdomain can make users' browsing faster.

Again, not necessarily. If it is served from the same server as your domain, it will be just like the speed of your main site.

4. A subdomain causes that particular area of your site to be indexed better by search engines.

Yet again, not necessarily. It's always a good practice to have a site map on your site for SE's to see almost every content in your site ;)

http://xxx.yourdomain.com

xxx is the subdomain

eg. http://abc.yourdomain.com

abc is a subdomain of yourdomain.com
