It's a pretty simple question I know.
When I hear the term "disk controller" I don't understand what's being referred to exactly.
So for example, I'm studying Oracle and they suggest putting the files on separate "Disks" as well as separate "Disk Controllers.'
I know what a hard disk is.
So in my PC for example, I have a 300 GB hard disk.
What would be its "disk controller?"
In a RAID setup for example, I can picture a set of different "hard disks", what would be its "disk controller?"
Is SCSI a disk controller?
Any feedback would be much appreciated.
