A Windows computer that is either part of a workgroup or belongs to a domain. So when it comes to the domain, we have to mention the Working Group, which is generally referred to as a peer network. A workgroup is usually a logical collection of not more than 10 computers, and if you want to manage more computers, MS recommends that you use domain mode for centralized management, which is more efficient. You can use domains, Active Directory, Group Policy, and so on to minimize the amount of network management effort.
