What is cold start (computer)?
Cold start is the process by which a computer is brought from shutdown or from a powerless state to a normal operating state. A cold boot refers to the general process of starting the hardware components of a computer, laptop, or server to the point where its operating system and all startup applications and services start.
Cold start is also known as hard boot, cold start or dead start.
A cold start is usually triggered by pressing the power button on a computer. A computer performing a cold start is already in a shutdown state in which no hardware, software, network or peripheral operations are taking place. Mostly a cold start is performed so that a computer can perform standard arithmetic tasks (general use). However, sometimes a post-software cold boot and usually hardware troubleshooting is required.
In contrast to a warm start, a cold start not only deletes the RAM contents, but also deletes the caches. This ensures that no traces or instances of conflicting programs or their data remain in the computer memory.
