Question about Warehouse equipment setup

So the Warehouse was more or less an endless stream of djs coming in to take over one after another. How does this work? There’s the same set of djing turntables for each to start spinning tracks? They just plug in their own laptop and start jamming? Sorry if this is dumb but I don’t fully understand how this works equipment-wise, and I’m legit fascinated how there were 0 breaks between sets. Kept the vibe going strong. Do other fests do this kinda setup of endless tunes because I loved it.
