What are the main similarities and differences between general linear series regulated power supply and switching regulated power supply? And their advantages and disadvantages?

Linear series regulated power supply adjusts the output voltage by adjusting the dynamic resistance of regulating tube, while switching regulated power supply adjusts the output voltage by adjusting the duty ratio or frequency of high-frequency AC pulse and the inductance and capacitance of energy storage elements.

The advantage of linear regulated power supply is small output ripple, but the disadvantage is low conversion efficiency and serious heating when the input-output voltage difference is large. The advantage of switching regulated power supply is high voltage conversion efficiency, but the disadvantage is large output ripple.
