The term "sync" is an abbreviation for synchronization. It refers to the process of bringing two or more things into a coordinated and timed relationship, usually by adjusting their relative positions in time. In other words, it means making sure that different elements are happening at the same time or in sequence with each other.
In practical terms, sync can refer to many different types of synchronization such as:
- Synchronizing audio and video signals so they play together smoothly (known as "lip synch" when done by a singer).
- Coordinating data transmission between two devices to ensure that information is received at the same time.
- Aligning multiple computer systems or databases to share information in real-time.
Overall, sync refers to any process of bringing different elements into harmony and ensuring they happen together correctly.
