Centralized and Distributed Computer Network Model

Another logical classification of computer networks is Centralized and Distributed Computer Network Model.

In Centralized computer network model, the network resources are placed and managed from a main location. Centralized network model allows administrators to manage the resources centrally (typically in Head Office). The network servers and other critical network resources are located in a central location in a secure and dedicated server room.

Centralized network model provides following advantages to Network and System Administrators.

Centralized network model provides Network and System Administrators better access to network devices

In Centralized network model, Network Resources can be managed more easily

Centralized network model provides better Network Security.

The main disadvantage is more work load of Network and System Administrators and increased risk of communication failure due to a catastrophe in the central location.

In Distributed network model, the network resources are placed and managed from different geographical locations. Designated network and system administrators manage the network resources in different locations. These days most of the Enterprise network models are distributed.
