There are whole languages dedicated to how your image may be represented on your screens, languages that direct how email is delivered and yet more, including this one, the one people understand.
We have a lot of terms around technical subjects and nomenclature is oft a reason to avoid breaking the ice and understanding even basic things. Language is a tool – and should never be a barrier – so this page is dedicated to clarity.
D
domain
Your address on the web
L
Lithium Cloud Hosting
Our mail server may send you messages. As this is its name, it may be from lithium.cloudhosting.co.uk. Do not worry. It is just a server name.
S
Subdomain
A secondary domain from your domain which can host a separate or website or service allowing extensions to make your site richer without also making it too complex to work on.
W
www
www is a subdomain of your main domain. Your main domain is used as the suffix for email addresses: e.g. yourname@abc.xyz
The domain, abc.xyz has a subdomain called www.abc.xyz – this is usually configured to load your domain website (so abc.xyz or www.abc.xyz would both load www.abc.xyz).
You should always use www. when referring to your website unless it is in an email address or if you actually want to refer to a subdomain which replaces www.
