Components: HDD configuration with an ATA cable

Which of the following hard disk configurations is supported with one ATA cable?
1. Up to seven SCSI drives
2. >>One or two IDE drives
3. Between one and four IDE drives
4. Up to fifteen SCSI drives

Explanation : An Advanced Technology Attachment (ATA) cable is used to connect Integrated Drive Electronics (IDE) drives to a motherboard. Each ATA cable can support up to two drives: a master drive and a slave drive. A computer usually has two ATA cables, so you can add four drives, two on each cable.

An ATA cable has only three connectors: a motherboard connector and two hard disk connectors. Therefore, it cannot support more than two IDE drives.

An ATA cable is not used to connect Small Computer Systems Interface (SCSI) drives. SCSI devices are attached in a chain with the first device connected to the host controller. The last device in the chain must be terminated.
