1. For computer networks, master-slave is a model for a communication protocol. A device or process (known as a master) controls one or more devices or processes (known as slaves). As soon as the relationship from master / slave is established, the control direction always goes from the master to the slave or to the slaves.
2. Master slave, which means master computer satellite, is a hierarchical concept for the organization and distribution of tasks between superordinate stations and subordinate computing units, the slaves. Such concepts are used whenever a computing unit assumes the control and task distribution of another.
