I've been using it in my bread machine and it works better than live yeast - not so much puffing and collapsing. But how does it work if it's.... er... inactive?

Yeast is live, de-activating it puts it into suspended animation. If they didn't it would carry on living in the packet, then die and go off. Then it would be dead.
The dried stuff isn't dead and can be re-activated by adding warm water.
It just means its dried but, people went through a phase of prefering live yeast to dried. So they changed the name from dried to de-activated!

Brewer's yeast is a good source of vitamin B, but live yeast tastes boring, it is poorly digested, and it can even strip vitamin B from the gut. Inactivated yeast lacks the disadvantages, but is still bland. The answer is autolysis: using the yeast's own enzymes to break it down.
Spent brewer's yeast is sieved to get rid of hop resins, and washed to remove bitter tastes. Then it is suspended in water at a temperature greater than 37 C with no nutrients: the yeast cells die, and vitamins and minerals leach out. Then the proteolytic (protein-splitting) enzymes take over, breaking the yeast proteins down into smaller water-soluble fragments, which also leach out.
The yeast cell membrane is unruptured during this time, and can be removed by centrifuging. The clear light brown liquid is then concentrated under a vacuum to a thick paste (the vacuum helps preserve flavours and vitamin B1, thiamine).

Like what people said. It's inactive but it gets 'activated' when it comes in contact with water and sugar. It's the only kind I use and it' easier and better.

The dry powder that you buy on the isle with the sugar and flour at the grocery store. When you add warm water and sugar it lives.
