How do liquids and gases exert pressure?

The same way paintball hurts, but at a lot smaller scale.
Gas molecules are fast moving projectiles that bump into all objects continuously, and reflect off all the walls of a vessel. Changing their direction takes a force, and the reaction force on the walls of the vessel is what we call pressure.

Very interesting question. Intuitively, think of a gas as an object that has particles that are spread out far and move relatively fast. Each particle, as a result, applies a tiny force to a small part of area containing the gas.
Additionally, Pressure is defined as Force/Area, or simply Force applied over an Area.
And since the Kinetic Molecular Theory of Gases leads us to the conclusion that all gases fill up their container completely, it can be derived that an equal amount of pressure is applied all around the container.
But as we decrease the volume of the container (by use of a piston), these gas particles cover less area compared to the previous volume, resulting in an overall increase in pressure (based on the definition of Pressure).
Thus, based on the nature of gas particles and their molecular movement, gases clearly exert pressure on their container.

The molecules of a gas are in a state of incessant, random motion inside the container.
The pressure of the gas is due to the force with which the molecules hit the walls of the container.
