> AT Attachment Packet Interface. A new protocol for
controlling mass storage devices similar to SCSI
protocols. It builds on the ATA (AT Attachment) interface,
the official ANSI Standard name for the IDE interface
developed for hard disk drives. ATAPI is commonly used for
hard disks, CD-ROM drives, tape drives, and other
devices.

><P
> Redudant Arrays of Inexpensive Disks. The basic idea of
RAID is to combine multiple small, inexpensive disk
drives into an array of disk drives which yields
performance exceeding that of a single large expensive
drive. There are five types of redundant array
Architectures; RAID-1 through RAID-5. A non-redudant
array of disk drives is referred to as RAID-0. Some RAID
systems can mix formats.

> Printing Performance Architecture. Protocol
developed by Hewlett Packard for their series of Deskjet
printers. In essence, the protocol moves the low-level
processing of the data to the host computer rather than
the printer. This allows for a low-cost printer with a
small amount of memory and computing power and a flexible
driver. However, this comes at the price of compatibility.
HP's decision was to develop drivers only for Windows 95
for this printer.
