Synchromism an early 20th-century art movement, commonly misspelled as Synchronism
Walt Disney's 1928 cartoon Steamboat Willie starring Mickey Mouse was the first to use a click track during the recording session, which produced better synchronism.
Bit-synchronous operation is a type of digital communication in which the data circuit-terminating equipment (DCE), data terminal equipment (DTE), and transmitting circuits are all operated in bit synchronism with a clock signal.
