That's a rocket with two stages- when the first stage (or section) runs out of fuel, it separates from the top half (second stage) and falls away, leaving that second stage to fire up, and drive the rocket higher.
The United States launched the first two-stage rocket in 1949, named the Bumper WAC. It was a combination of a V-2 missile and a WAC Corporal rocket.

a multistage rocket is a rocket. a rocket could be a multistage rocket. all multi-stage rockets are rockets, but not all rockets are multi-stage. For example the space misstions. They are all multi staged, but each stage is a rocket on its own.

Typically, a rocket can have multiple stages, ranging from two to four stages. Each stage is responsible for providing thrust during a specific portion of the ascent to space, with each stage being jettisoned once its fuel is depleted. As each stage is discarded, the rocket becomes lighter and more efficient for reaching its target orbit.
Because it's moving a smaller mass. The first stage of the rocket has to move the whole vehicle. By the time you're ready to fly on the third-stage engines, you've burned up the fuel in the first two stages and separated from them.
A single-stage rocket has all its propulsion and structure contained in a single unit, while a multistage rocket consists of two or more stages stacked on top of each other. In a multistage rocket, each stage is jettisoned when its fuel is exhausted, shedding weight and making the spacecraft lighter, enabling it to achieve higher speeds. This design allows multistage rockets to carry heavier payloads and go farther into space than single-stage rockets.
The first stage of a multi-stage rocket is called the booster stage. It is responsible for providing the initial thrust needed to lift the rocket off the ground and begin the ascent to space. Once its fuel is expended, it separates from the rocket to reduce weight and allow the next stage to continue the journey.
One of the key factors in rocketry is the weight of the rocket. By designing a rocket that ejects parts of the rocket that has emptied it's fuel tanks decreases the overall weght of the rocket, extending the flight of the rocket.
Liftoff: The rocket engines ignite, propelling the rocket off the launch pad. Ascent: The rocket climbs through the Earth's atmosphere, reaching higher altitudes and increasing speed. Orbit insertion: The rocket reaches a velocity that allows it to enter orbit around the Earth. Space travel: Once in orbit, the rocket can perform maneuvers to reach its destination in space.
