If you have more than one computer, or if your one computer connects to the internet, then you have a Network. Your network probably contains Client computers, and Server computers. Your network contains one or more groups of computers (even with one computer, you have a group of one) - Domains, and / or one or more Workgroups.
- If your computer accesses data on another computer - either another computer that's yours, or that's on the Internet, then you have a Client.
- If your computer provides, or offers to provide, data to another computer, you have a Server.
- Most Windows computers perform as both clients, and servers, at the same time.
- Membership in a domain or workgroup gives the ability to easily identify the computers that you need access to the most. This is other computers in your domain or workgroup.
- If your network includes a special Server that validates access for another Server, you have a Domain.
- If validation of access on your Network simply consists of setting up an account on each individual Server (and maybe a matching account on the Client), then you have a Workgroup.
