Back when wr used parallel IDE, most motherboards only had two IDE connections. Each connection could support two devices, a master and a slave. If you had a hard drive and a CD-ROM, it was best to put them on separate channels. This is because only one device could talk at a time, and the slower CD-ROM would block the faster hard drive from operating. If you had to put them on the same channel, then the hard drive should be the master so it gets priority.
Then there’s scsi. My family wasn’t rich enough to have scsi shit when I was growing up, but I do know a few things. On paper, it’s very simple; give each device a unique ID on the bus, and then attach terminator blocks at each end. I’m also aware that, in practice, this description is a cruel joke.
