master/slave

In computer networking, master/slave is a model for a communication protocol in which one device or process (known as the master) controls one or more other devices or processes (known as slaves). Once the master/slave relationship is established, the direction of control is always from the master to the slave(s). The County of Los Angeles, saying the term master/slave may be offensive to some of its residents, has asked equipment manufacturers not to use the term. Some manufacturers prefer the term primary/secondary.

Other communication protocol models include the client/server model, in which a server program responds to requests from a client program, and the peer-to-peer model, in which either of the two devices involved can initiate a communication session.

I for one have to ask, are the creators of the "master/slave" term that unaware of the times? These folks have to get out in to the fresh air, now and then.

The terminology has been in use for literally decades, long before 50 Shades. :)
