ZEBIBYTE
(abbreviation "ZiB"
1,180,591,620,717,411,303,424 (270) bytes, and is the unambiguous name for 'Zettabyte to denote the true binary value.
ZETTABYTE
(abbreviation "ZB"
1,180,591,620,717,411,303,424 (270) bytes to be precise, but frequently used to mean roughly a thousand million million million bytes (1021), or 1024 Exabytes. The unambiguous name 'Zebibyte' can be used for the true binary value.
ZIP (pronounced "zip") A compression program that is still popular in MS-DOS environments, but has been superceded by WinZip in Windows environments. It is fairly rare now in the Amiga environment, although there is still the odd file around that has been compressed using Zip.
ZIP DRIVE A floppy drive format produced by Iomega which used special disks capable of storing 25MBs, 100MBs or 250MBs of data depending on the type of drive being used. It came in three flavours; SCSI which works on Amigas with SCSI, Parallel which works on the A1200 and A4000, and USB which works on the AmigaOne.
ZIP SOCKETS A type of memory chip socket designed for chips where the legs projecting from the chips look like a zipper.

ZMODEM ("Z-mo-dem") A software based error correction protocol for the transmission of data using a modem. This is the preferred protocol when up/downloading on a BBS.
ZOO One of the older compression utilities that used to be common on the Amiga. See also Arc, Archive, LhA and LhArc.
ZORRO The name originally coined as the name of the original Amiga 1000 prototype.
ZORRO BUS The Zorro bus is the standard for Amiga expansion cards (i.e not PC expansions which use a PC type connector) on the Amiga box models from the Amiga 2000 up. One of the main features of the Zorro bus is Autoconfig. On other computer systems you have to configure cards manually via "jumpers" or DIP switches for certain address areas or interrupt numbers. This is very tedious and, in practice, it requires in-depth knowledge of the system to avoid conflicts among different cards used simultaneously. The Autoconfig mechanism of the Amiga system automates this procedure totally, so that the user never has to bother with such details. Thus, expanding an Amiga system is extremely simple and without problems. In the A2000 it was the Zorro-II bus which was 16 bits wide.
ZORRO I The original 16 bits wide Zorro expansion board connector used by the A1000.
ZORRO II The improved 16 bits wide Zorro bus that is standard for expansion cards on the Amiga B2000 and A2500.
ZORRO III The 32 bits wide Zorro bus that is standard for expansion cards on the Amiga A3000 and A4000.
