Synchronization (computer science)

In computer science, synchronization refers to one of two different but related concepts: synchronization of processes, and synchronization of data.

• Process synchronization refers to the idea that multiple processes are to link or handshake at a certain point, so as to reach an agreement or commit to a certain sequence of action.
• Data synchronization refers to the idea of keeping multiple copies of a dataset in coherence (in-constancy) with one another, or to maintain data integrity.

Process synchronization is commonly used to implement Data synchronization.
