How does pascal's principle describes the transmission of pressure through a fluid?

Pascal's principle states that when pressure is applied to a confined fluid at rest, that pressure is transmitted undiminished in all directions throughout the fluid. This means that any change in pressure applied to one part of the fluid is felt equally at every point within the fluid, regardless of the shape or size of the container. As a result, this principle underlies the operation of hydraulic systems, where a small force applied to a small area can generate a larger force over a larger area.
