Hi, I'm intrigued to find out how the URL's on eBay work. The main domain name for eBay is: www.ebay.co.uk, but the signup page is www.signup.ebay.co.uk. How are the www.signup.ebay.co.uk (Sub domains) created?

Subdomains are simply created within the DNS server and act as a totally separate domain name although without the need of a different registered domain name.

It is to say that even "www" is a sub-domain. The 'pure' domain name consists simply of the label and the top-level domain, e.g. "sunnyscript.com" or generally "domain.tld".
Depending upon your webhoster, they will either offer sub-domains free of charge or for a small fee. As it was already explained, creating sub-domains just means to add an additional line to your domain's DNS record.
Sub-domains are unique in the sense that no one else can register "you.domain.tld", but would be able to set up "you.mydomain.tld".

It's interesting that different hosting providers offer different services where sub domains are concerned.
Basically, if you create a sub-folder in your publically accessible folders and put an index.html page in it - you've created a sub-domain.
With almost any provider you can access the sub domain using 'www.yourdomain/subfoldername'.
If your provider permits, you can access with 'subfoldername.yourdomain'.
Some even provide separate ftp access to the sub domain.

Sure, but for example http://www.sunnyscript.com/demo/ isn't a sub-domain, it is just a path to the folder /demo within your web home directory. A sub-domain would be http://demo.sunnyscript.com instead of.
It's exactly what you point out, if your provider allows, you can use demo.sunnyscript.com, but this requires changes to the DNS and also some adjustments at the web server configuration. And this is a service that, depending upon the pricing calculation of the webhoster, is a paid service.
It is more common at discount hosters offering this free of charge, while "service-oriented" hosters are charging for this. Sounds strange, but is reality ;-)
