Q1: The ATAPI compliance is stands for?

ANS:C - Mass storage device

Modern mass storage devices include all types of disk drives and tape drives. Mass storage devices retain data even when the computer is turned off.

ATA Packet Interface (ATAPI) is a protocol that has been added to Parallel ATA and Serial ATA[1] so that a greater variety of devices can be connected to a computer than with the ATA command set alone. It carries SCSI commands and responses through the ATA interface. ATAPI devices include CD-ROM and DVD-ROM drives, tape drives, magneto-optical drives, and large-capacity floppy drives such as the Zip drive and SuperDisk drive.

A mass storage device may also be referred to as an auxiliary storage device. The term is commonly used to describe USB mass storage devices.

ATAPI (AT Attachment Packet Interface) is an interface between your computer and attached CD-ROM drives and tape backup drives. Most of today's PC computers use the standard Integrated Drive Electronics (IDE) interface to address hard disk drives.
