Master/slave
Master/Slave is a model for a communication protocol where one device or process has unidirectional control over another (or others). Once a master/slave relationship between devices or processes is established, the direction of control is always from the master to the slave(s). This term is commonly used to refer to a way to denote hard drive arrangements.
In November of 2003, The County of Los Angeles, stated in an e-mail that the term master/slave may be offensive to some people who live in the county, and had asked equipment manufacturers not to use the term. Here is the e-mail that was sent verbatim:
- Subject: IDENTIFICATION OF EQUIPMENT SOLD TO LA COUNTY
- Date: Tue, 18 Nov 2003 14:21:16 -0800
- From: "Los Angeles County"
- The County of Los Angeles actively promotes and is committed to ensure a work environment that is free from any discriminatory influence be it actual or perceived. As such, it is the County's expectation that our manufacturers, suppliers and contractors make a concentrated effort to ensure that any equipment, supplies or services that are provided to County departments do not possess or portray an image that may be construed as offensive or defamatory in nature.
- One such recent example included the manufacturer's labeling of equipment where the words "Master/Slave" appeared to identify the primary and secondary sources. Based on the cultural diversity and sensitivity of Los Angeles County, this is not an acceptable identification label.
- We would request that each manufacturer, supplier and contractor review, identify and remove/change any identification or labeling of equipment or components thereof that could be interpreted as discriminatory or offensive in nature before such equipment is sold or otherwise provided to any County department.
- Thank you in advance for your cooperation and assistance.
