Slow is the goal, deposit method.
Use slow deposit methods to achieve the purpose.
Why slow? Slow is an indicator of the stability of the system.
For example: a power supply voltage changes slowly, it means the power supply voltage is relatively stable.
You can keep the change slows, because the system can be kept nearby to take resources, rather than to take away resources.
Charge stored in the capacitor can ensure the stability of the load voltage. When the load voltage increases, the capacitance can be powered from near where the accelerated speed to take power.
Inductor current can be saved, to ensure the stability of the load current. When the load current is increased, it can be powered from nearby inductors where accelerated speed to take power.
The CPU has a cache, and accelerate the speed instruction fetch data. Long-haul distances without causing the CPU to take data from the memory.
Every life has a tank for buffering the water to improve the convenience of water. Can respond to emergencies day does not turn on the water.
