cold start

[′kōld ′stärt]
(computer science)
To start running a computer program from the very beginning, without being able to continue the processing that was occurring previously when the system was interrupted.

cold boot

Starting the computer when its power is turned off. To perform a cold boot if the computer is running, select Shut Down. Once the machine is off, turning it back on performs the cold boot.

If the computer locks up, a cold boot is necessary because a restart ("warm boot") may not be sufficient. A cold boot removes power and clears memory (RAM) of all internal data and counters that keep track of operations, which are created by the OS and applications when they run. Erratic program behavior is often cured with a cold boot, also known as a "hard boot."

Remove the Power
Even when shut down, computers may occasionally retain settings in RAM. The only way to absolutely guarantee RAM is cleared is to remove the power source, which means unplugging a desktop computer or removing the battery in a laptop. Laptops with non-removable batteries are typically cold booted (reset) by holding down the power button for 10 or more seconds. Sometimes another key or button must be pressed along with the power button.

A/V Equipment
TVs, A/V receivers and set-top boxes generally draw power when turned off, and they must be cold booted by removing their power cables to reset them. Contrast with warm boot. See boot, clean boot and hard reset.

In response to Cold Start, Pakistan formulated its 'Full Spectrum Deterrence' policy, which, according to the National Command Authority statement of September 2013, maintains that 'Pakistan would not remain oblivious to the evolving security dynamics in South Asia and would maintain a full spectrum deterrence capability to deter all forms of aggression.'
Figure 9 is a pie chart that shows the compositions of NMOG (E85 fuel) slipping out of close-coupled TWC with underbody TWC aftertreatment system during cold start (from 0 to 50 seconds measured by FTIR), which counts for 80-90% of the total NMOG emission over FTP-75.
There are tactical and operational challenges in carrying out Cold Start which has dissuaded the Indian Army to operationalize this doctrine.
To better evaluate the cold start performance of the aftertreatment system during the FTP-75, the entire cycle was divided into 4 sections.

Singh also reiterated similar views, stating, "There is nothing like Cold Start, but we have a 'proactive strategy' which takes steps in a proactive manner to achieve our objectives".
