We call them primary and secondary too, but channels and controllers are 
different.  A controller is the chip on the *motherboard* that the sockets on 
the motherboard connect to.  There is one controller in a typical PC -- 
usually with two (primary + secondary) IDE channels.  Each channel can have a 
master and a slave device.

If you added another IDE controller card in a PCI slot, you'd have four IDE 
channels, for a maximum of eight devices.  Of course, special controller 
cards might provide even more.
