SCADA will perform supervisory action over Distributed control system to make sure that every thing is working fine.
The difference between distributed system and multiprocessor system is whether the processing units in the system share the main memory. If yes, then the system is multiprocessor system; otherwise, it's a distributed system.
In centralised tasks are done by one system and in distributed tasks are shared by the many computers
No. But most distributed control systems ARE digital.
there is no proper knowledge regarding this question.
The controls are seperated
Difference between control process and process control is that system control process is typically the large scale version of where process control is used.

On a computer network, operating systems communicate with each other. In a distributed operating system, a single OS is communicating with itself across multiple machines.

Distributed processing involves multiple interconnected systems working together to complete a task, with each system performing a different part of the task. Parallel processing, on the other hand, involves breaking down a task into smaller sub-tasks and executing them simultaneously using multiple processors within the same system. In distributed processing, systems may be geographically dispersed, while parallel processing occurs within a single system.
