Synchronization of multiple interacting [[dynamical system]]s can occur when the systems are [[Self-oscillation|autonomous oscillators]]. Poincaré phase oscillators are model systems that can interact and partially synchronize within random or regular networks.<ref name="Nolte">{{cite book | first = David | last = Nolte | title = Introduction to Modern Dynamics: Chaos, Networks, Space and Time | publisher = [[Oxford University Press]] | year = 2015 }}</ref> In the case of global synchronization of phase oscillators, an abrupt transition from unsynchronized to full synchronization takes place when the coupling strength exceeds a critical threshold. This is known as the [[Kuramoto model]] phase transition.<ref name=":1">{{Cite web|url=https://www.youtube.com/watch?v=t-_VPRCtiUg|title = The Surprising Secret of Synchronization|website = [[YouTube]]}}</ref> Synchronization is an emergent property that occurs in a broad range of dynamical systems, including neural signaling, the beating of the heart and the synchronization of fire-fly light waves.

Synchronization is important in [[digital telephony]], video and [[digital audio]] where streams of sampled data are manipulated. Synchronization of image and sound was an important technical problem in [[sound film]]. More sophisticated film, video, and [[sound|audio]] applications use [[time code]] to synchronize audio and video.{{citation<ref needed|datename=March":1" 2020}}/> In movie and television production it is necessary to synchronize video frames from multiple cameras. In addition to enabling basic editing, synchronization can also be used for [[3D reconstruction]]<ref>Moore, Carl, et al. "[https://ieeexplore.ieee.org/abstract/document/5636714/ Synchronization of images from multiple cameras to reconstruct a moving human]." 2010 IEEE/ACM 14th International Symposium on Distributed Simulation and Real Time Applications. IEEE, 2010.</ref>

In [[electric power]] systems, [[alternator synchronization]] is required when multiple generators are connected to an electrical grid.

[[Flash synchronization]] synchronizes the [[Flash (photography)|flash]] with the [[Shutter (photography)|shutter]].

Some systems may be only approximately synchronized, or [[plesiochronous]]. Some applications require that relative offsets between events be determined. For others, only the [[Partially ordered set|order]] of the event is important.{{citation<ref needed|datename=March"Nolte" 2020}}/>
