Cold Start

Cold Start: In computing, a cold start refers to powering up a device or system from a completely off state, as opposed to a warm start or reboot, which involves restarting the system without interruption to power. In the context of cloud services or big data, it can also refer to the challenge of making accurate recommendations or decisions when there is insufficient data about users or items, commonly faced by recommendation systems.
