Step-by-step explanation:
The student's question is about the specifications of SATA revision 2.0, which refers to the second generation of the Serial ATA interface standard used for connecting motherboards to mass storage devices, like hard drives and optical drives. SATA revision 2.0 (also known as SATA 3Gb/s) specifies a maximum cable length of 1 meter (e) and supports a data transfer rate of up to 3 Gbps (d). It does not support a 6 Gbps data transfer rate or a maximum cable length of 2 or 3 meters.
