Explanation

The AT Attachment-7 (ATA-7) standard supports transfer mode UltraDMA/133. With the market introduction of Serial ATA, the ATA is sometimes referred to as Parallel ATA (PATA). What is Parallel ATA (PATA)? Parallel ATA (PATA) is a standard interface for connecting storage devices such as the hard disk and CD-ROM drive inside a computer. It is the most common and least expensive interface for connecting storage devices. A PATA ribbon cable uses either a 40-conductor or an 80-conductor wire and is limited to 46 cm length. The new 80-wire ribbon cable appeared with the introduction of the Ultra DMA/66 mode. All forty additional wires in the new cable are ground wires, interleaved with the previously defined wires. The extra forty conductors are all ground lines, placed there to provide additional shielding and protection against crosstalk between conductors. A maximum of two devices can be connected to a PATA port. Parallel ATA (PATA) 133 has a data transfer speed of 1064 Mbps. Answer option A is incorrect. The AT Attachment-6 (ATA-6) standard supports transfer mode Answer option D is incorrect. The AT Attachment-5 (ATA-5) standard supports transfer mode Answer option C is incorrect. The AT Attachment-4 (ATA-4) standard supports transfer mode http.//en.wikipedia.org/wiki/Advanced_Technology_Attachment#Parallel_ATA
