Url issues

1. How can I register a URL.

2. Will I own it exclusivly?

3. Will it be universal or only on certain servers?

4. How can I increase its visibility/access?

>1. How can I register a URL.

http://dotster.com is a good service to register a domain name.

>2. Will I own it exclusively?
you don't own the url, but 'own the license" of the url and pay a yearly fee
to use it exclusively during that period. You can
pay up to 10 years fees in advance. To protect your domain name,
it is best to trademark it with uspto.gov for your specific use.

>3. Will it be universal or only on certain servers?

yes, domains will work on any Internet server. it is an internet standard. domains
need to be added to servers IP, but that is handled with your hosting provider.

>4. How can I increase its visibility/access
first step. submit your domain name/url with search engines
