Master/slave (technology) - Examples

Examples

  • In database replication, the master database is regarded as the authoritative source, and the slave databases are synchronized to it.
  • Peripherals connected to a bus in a computer system.
  • Railway locomotives operating in multiple (for example: to pull loads too heavy for a single locomotive) can be referred to as a master/slave configuration - with the operation of all locomotives in the train slaved to the controls of the first locomotive. See - Multiple-unit train control.
  • Duplication is often done with several cassette tape or compact disc recorders linked together. Operating the controls on the master triggers the same commands on the slaves, so that recording is done in parallel.
  • In parallel ATA hard drive arrangements, the terms master and slave are used but neither drive has control over the other. The terms also do not indicate precedence of one drive over the other in most situations. "Master" is merely another term for device 0 and "slave" indicates device 1.
  • On the Macintosh platform, Target Disk Mode allows a computer to operate as an external FireWire hard disk, essentially a disk slave mode. Some older pre-FireWire Macintoshes had a similar controversial "SCSI Disk Mode".

Famous quotes containing the word examples:

    In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.
    Michel de Montaigne (1533–1592)

    No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.
    André Breton (1896–1966)

    There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.
    Bernard Mandeville (1670–1733)
