What is cold plugging?
Cold-plugging refers to the situation when a computer needs to be turned off to add or remove a component, or to allow a device to synchronize data with the computer. Cold mating is often used as an extra precaution to ensure that a component will not be damaged when it is removed or replaced. It is particularly used in modules that are volatile to static electricity, such as B. Printed circuit boards. A cold device that in the running business Replacing it may cause malfunction and damage to the device or system. Also known as a cold swap.
In most PCs, the CPU and memory are examples of cold plug-in components. However, CPUs are not always cold-pluggable - they are often hot-pluggable in high-end servers and mainframes. The opposite of cold plugging is hot plugging. A hot-pluggable device can be replaced without shutting down the computer. A common hot-swappable device used by most users is a universal serial bus (USB) connection. In certain contexts, a cold plug is defined so that it can remove or add a component without requiring a restart, but it cannot recognize the changes until after a restart. (In this case, a hotplug would be defined in such a way that it can detect changes without restarting.)
