On a linear supply, the AC cord connects to a large 60Hz power transformer the secondaries of which are rectified.

On a switch mode supply, the AC cord connects to a diode bridge and some LARGE capacitors...Then to a switching transistor a small high-frequency transformer and some additional smaller rectification and filtering.

The idea of switch mode is the higher freq the smaller and cheaper the trans, and regulation and protection is built in by design.
