I think of a server as having several large hard drives and the related
hardware so that it can act as a large database. The subject is too
complicated for a brief description.
How servers work is described in "howstuffworks", "How Domain Servers
Work". It seems that each server is a large database and that they all
can communicate with one another and that several servers communicate
with each other to reach the desired information. The same information
may be stored on more than one server so that if one server fails the
information will not be lost.
Why do you want to get a server? Is your present server not working
right, likely to fail, or not large enough? Do you want to replace it? Do
you want to store a copy of the information on your present server on
Will you have backup power supplies on your servers?
