A disk array controller is a device that manages the physical disk drives and presents them to the computer as logical units. It often implements hardware RAID , thus it is sometimes referred to as RAID controller .
I2C and I3C are also an example of master-slave technology. Modbus uses a master device to initiate connection requests to slave devices. An edge-triggered flip-flop can be created by arranging two gated latches in a master–slave configuration. It is so named because the master latch controls the slave latch's value and forces the slave latch ...
