In technology, a device or process that is controlled by another, higher-level device or process (the 'Master').
example
Bei älteren Festplatten musste man per Jumper einstellen, welche die Master- und welche die Slave-Festplatte ist.
With older hard drives, you had to use a jumper to set which one was the master hard drive and which one was the slave hard drive.
Usage tips
Technical context only
This word is a technical term from technology and IT that was borrowed from English. It refers exclusively to a subordinate, controlled device or process and never to a person.
EXAMPLE
Die zweite Festplatte ist als Slave konfiguriert.
The second hard drive is configured as a slave.
Context clue: Master
The word 'Slave' almost always appears together with its counterpart 'der Master' (the master). If you read about a 'Master-Slave-Konfiguration' (master-slave configuration) or a 'Master-Slave-Prinzip' (master-slave principle), this technical meaning is always intended.
EXAMPLE
Das Master-Gerät sendet die Befehle an alle Slaves im Netzwerk.
The master device sends the commands to all slaves in the network.
Typical verbs
In a technical context, 'Slave' is often combined with verbs such as 'einstellen' (to set), 'konfigurieren' (to configure), or 'fungieren' (to function/serve as).
EXAMPLE
In diesem System fungiert der kleine Sensor als Slave.
In this system, the small sensor functions as a slave.

Slave vs Master
master
'der Master' and 'der Slave' form an opposite pair in technology. 'Der Master' is the higher-level element and controls other parts. 'Der Slave' is the dependent device or dependent process that is controlled by the master. The words can be confused because they often appear together in the same technical description. What matters is the direction of control: the master gives the instructions, the slave follows.
Slave
Wenn der Master ein Signal sendet, reagiert der Slave automatisch.
When the master sends a signal, the slave reacts automatically.
Master
Der Master startet den Prozess und sendet die Daten an die anderen Geräte.
The master starts the process and sends the data to the other devices.
