👉 A sync is a process or event that occurs automatically between two or more devices in a network, such as a computer and its peripherals, or between a device on one end of the network and another device on the other. It can take place when a device connects to the internet and then establishes a connection with a server or client, allowing data to be shared across the network. Syncs are essential for maintaining connectivity and ensuring that devices are communicating correctly with each other.
