The term "bus"

What does the term bus mean? I keep finding different answers for the word and now i am unsure. Can someone please help?

it just means channel or track i think


The term “bus” comes from assigning multiple channels to a single channel which would control all of the channels assigned to it, taking those channels where you wanted them to go or “bussing” them.

At least that’s what I remember from my digital audio and foley class taught by, oddly enough, Professor Buss.

Is that what the send parameters in Ableton are for?
