As we know that in any centralized computer network system all the resources are stored or managed at one place (computer system).
This makes is easy for system administrator to keep all that resources consistent and in accurate form. While in distributed system all the sites containing the data and resources need to be managed. We can easily back up the data that is only at one place. It is also very much easy to protect the system from authorized access because there is only site on the network that needs protections.
The centralized device is normally known as the server that is responsible of managing all the processing and controlling. Only the administrator has access to the server. All the other clients on the network request the services from the server. The administrator is in charge to assign the rights to these different users/clients that request the services.
Besides all these advantages, there are a number of shortcomings attached with this centralized approach.
As there is a central device containing all the network resources, thus there is only a single point of failure. It means if this central device create some problem, the entire network will suffer a fall down. This central device has to handle all the clients with various requests so, it must be powerful enough to fulfill this task efficiently.
