The smallest cymbals associated with a drum set are called splash cymbals.
A standard drum set typically includes a bass drum, snare drum, hi-hat cymbals, tom-toms, a ride cymbal, and a crash cymbal.
A drum kit will contain at least four drums. It will also have a floor tom, hanging toms, a hi-hat, a ride cymbal, a splash cymbal, and a ride cymbal.

A crash cymbal is a type of cymbal in a drum kit that produces a loud, explosive sound when struck with a drumstick. It is used to add emphasis, accents, and dramatic effect to the music being played.
The typical drum kit setup used by most drummers includes a bass drum, snare drum, hi-hat cymbals, ride cymbal, crash cymbal, and tom-toms.
The essential components of a basic drum setup include a bass drum, a snare drum, tom-toms, cymbals (such as hi-hats, crash cymbal, and ride cymbal), a drum throne (seat), and hardware like stands and pedals.
A simple drum kit is composed of several basic elements. The drums include the Snare drum (The one with the wires under it), the toms (The drums with out the wires but are hit with a stick, including the mounted ones and the ones that are on the floor, which are floor toms), and the bass drum(s).
