Which of the following systems does not operate in a master-slave fashion?

Correct option is C

The Client-server architecture does not operate in a master-slave fashion. Instead, it follows a distinct communication model where clients request services, and servers provide those services without a hierarchical or dependency structure seen in master-slave setups.
Important Key Points:
1. Client-server architecture involves independent clients requesting services from a central server, where the server responds to these requests without being in a continuous control state as in a master-slave system.
2. It is characterized by a request-response communication pattern, not the dependency or control relation typical of master-slave systems.
Knowledge Booster:
· Database Replication: Often follows a master-slave approach where changes on the master are propagated to one or more slave databases.
· Peripheral Communication in a Computer System: Typically uses a master-slave model where the CPU (master) controls peripheral devices (slaves).
· Robotics Control Systems: Sometimes implement master-slave configurations to synchronize actions of different robot components.
· Sensor Networks with a Central Controller: Often have a central controller (master) coordinating and collecting data from distributed sensors (slaves).
