Hello, I am NEW here.

I have sort of a dumb question and don't know where to ask.
How does a local doctors office computers work together on a network server? Is there any diagrams and text explaining all of this?

Let's say a local business has 6-8 offices and needs a computer connection in each office to a main Network Server in this business office. No Internet connection needed, they just need to share infomation with each other. What does each office need to connect to it's main server? Does each office have to have a complete computer system with a hard drive to network to their main server?

Thanks, Mike
