First, I am a complete novice when it comes to programming, so pardon my ignorant questions.
I hired two programmers to work on my project. They say they need a remote test server for testing things, before making it live, so that the changes are not live until all are okay.
So, my questions:
What are Remote Test Servers?
Why are they necessary?
Can they be set up with normal reseller or shared hosting?
How can you prevent the world from seeing what's on it?
Do you need a domain name for this?
How do I go about setting up a remote test server?
Any other comprehensive document to read up on this?
Thanks.
