State three common interface types used to connect hard disk drives to a computer motherboard.

### Why this is right A drive interface sets the rules for how a hard disk drive connects to the computer and exchanges data with its controller. Serial ATA (SATA), Parallel ATA (PATA), and Small Computer System Interface (SCSI) are established interface families, so all three are valid examples. ATA stands for Advanced Technology Attachment. ### The concept SATA sends data serially, one bit at a time over a link. PATA sends several bits at once over a ribbon cable and is commonly called Integrated Drive Electronics (IDE), especially when referring to older drives. SCSI is a separate interface family for connecting and managing storage devices, often used in workstations and servers. IDE is commonly associated with PATA, while SATA and PATA are both part of the ATA family. | Interface | How it communicates | Common association | |---|---|---| | SATA | Serial data over a link | Modern personal computers | | PATA/IDE | Parallel data over a ribbon cable | Older personal computers | | SCSI | Uses SCSI-family commands and connections | Workstations and servers | ### What a good answer covers - Names SATA, or Serial ATA. - Names PATA, or Parallel ATA, and recognizes IDE as its common older name. - Names SCSI, or Small Computer System Interface. - Identifies them as connection and communication interfaces, not types of storage capacity. ### Terms - **SATA**: Serial ATA, where ATA means Advanced Technology Attachment. It sends data serially between a drive and its controller. - **ATA**: Advanced Technology Attachment. The interface family that includes SATA and PATA. - **PATA**: Parallel ATA. An ATA interface that transfers data in parallel. - **IDE**: Integrated Drive Electronics. A common name for older PATA drives and their interface. - **SCSI**: Small Computer System Interface. An interface family for connecting and managing storage devices. - **Interface**: The connection and communication rules that let a computer and a device exchange data. - **Controller**: The circuitry that manages communication between a computer and a connected device. - **Motherboard**: The computer’s main circuit board, which connects the processor, memory, and other components. ### Remember Think of SATA as the serial ATA interface, PATA/IDE as its older parallel counterpart, and SCSI as a separate interface family.
