Digital Forensic Certification Practice Exam

Which disk interface allows personal computers to communicate with various peripheral hardware?

1. SATA

2. USB

3. SCSI

4. IDE

The correct answer is: SCSI

The correct choice is SCSI, which stands for Small Computer System Interface. SCSI is a set of standards for connecting and transferring data between computers and peripheral devices like hard drives, scanners, and printers. It supports a wide range of devices, allowing multiple devices to communicate simultaneously over a single connection, making it a versatile option for personal computers. SCSI is known for its high performance and is often used in servers and workstations where speed and efficiency are critical. While other interfaces like SATA, USB, and IDE also allow communication between computers and peripherals, they have specific use cases and limitations. For instance, SATA is primarily designed for connecting storage devices like hard drives and SSDs, USB is widely used for various devices but has limitations in terms of speed and simultaneous connections, and IDE is an older interface that has largely been replaced by SATA for disk drives. SCSI, with its ability to handle multiple device types and support for high-speed data transfer, is particularly notable in environments where various peripherals need to connect and communicate effectively with personal computers.
