The concept of a Dyson Sphere is a megastructure built around a star in order to harness all of its energy. The idea has many variants, but the main three are the Dyson Bubble, Shell, and Swarm.
They all perform the same job, harnessing a stars energy. The Dyson Swarm is one form of the Dyson Sphere, which has multiple satellites orbiting the star in a specific organized manner. There are many forms, but the most popular is the Dyson Ring. The Dyson Ring is a group of solar powered satellites or space habitats that form a large ring around the star, taking in all of its energy. Some aspects about the Dyson Swarm that are good is that it could be constructed incrementally, and that the parts could be sized as necessary, but there could also be an instance where satellites could overlap another's orbit, and cover it temporarily.
The Dyson Bubble could also be constructed incrementally, and is in my opinion, the most efficient design. Just like the Dyson Swarm, it has a bunch of satellites orbiting the star, but in this case, they aren’t organized and just float around.
The Dyson Sphere is the most inefficient and dangerous of the three. It encases the entire area of the Earth to the Sun in a giant metal bubble, and the energy radiating from the sun is kept within the bubble for humabs to use. It is the most dangerous because of the amount of passing comets and asteroids, which are all able to break through or severely damage the Sphere. It will take the longest time to build because it cannot be built incrementally.
