In writing academic research, how can you overlap in topic areas between domains? Do you have any examples?

If you are talking about domains. Other services like DNS, DHCP comes into play. Also, you can talk about OS which is important for carrying out about services. One can use the same domain and include multiple users under the wing or choose to have many domains as well. Domain and Active Directory works on top of each other to serve their purpose. So you can look into that as well. Thanks

Overlapping is a common tendency. It is the writer's talent and common rule of writing - no overlapping or duplication.

An exact writing plan and genuineness can create a good paper
