1394
(foldoc) | High Performance Serial Bus
1394
FireWire
IEEE 1394
I-Link
(Or "IEEE 1394") A 1995 Macintosh/{IBM
PC} serial bus interface standard offering isochronous
real-time data transfer.
1394 can transfer data between a computer and its peripherals at
100, 200, or 400 Mbps, with a planed increase to 2 Gbps.
Cable length is limited to 4.5 m but up to 16 cables can be
daisy-chained yielding a total length of 72 m.
It can daisy-chain together up to 63 peripherals in a tree-like
structure (as opposed to SCSI's linear structure). It allows
peer-to-peer communication, e.g. between a scanner and a
printer, without using system memory or the CPU. It is
designed to support plug-and-play and hot swapping.
Its six-wire cable is not only more convenient than SCSI cables
but can supply up to 60 watts of power, allowing low-consumption
devices to operate without a separate power cord.
Some expensive camcorders included this bus from 1995. It is
expected to be used to carry SCSI, with possible application to
home automation using repeaters.
Sony calls it I-Link, most people call it "FireWire".

Z39.50
Information Retrieval Service
Definition and Protocol Specification for Library
Applications, officially known as ANSI/NISO Z39.50-1992, and
ANSI/NISO Z39.50-1995. This standard, used by WAIS,
specifies an OSI application layer service to allow an
application on one computer to query a database on another.
Z39.50 is used in libraries and for searching some databases
on the Internet. The US {Library of Congress
(http://lcweb.loc.gov/z3950/agency/)} is the official
maintanence agency for Z39.50.
Index Data, a Danish company, have released a lot of Z39.50
code. Their website explains the relevant ISO standards
and how they are amicably converging in Z39.50 version 4.0.

IBM390
IBM zSeries
(Enterprise System Architecture) An IBM
mainframe computer introduced in 1988. Successor to the
IBM 370XA had enhanced access registers that allowed access
to other forms of virtual memory. This enhancement allowed
more data storage in main and virtual memory, reducing I/O
operating and improving speed and efficiency. The IBM 370ESA
was rebranded as the IBM390, and later as the zSeries.

os/390
(foldoc) | OS/390
An IBM mainframe operating system,
featuring integrated MVS, UNIX, LAN, {distributed
computing} and application enablement services through its
base elements. These base services enable open, distributed
processing and offer a foundation for object-ready application
development. The OS/390 base includes a {Communication
Server} that includes VTAM, the VTAM AnyNet feature,
TCP/IP and TIOC. It provides SNA (3270), APPC,
High Performance Routing, ATM support, sockets and
RPC.
OS/390 is basically rebranded, repackaged MVS/OE, CMOS
processors, RAMAC disk arrays and open systems extension
to networking in VTAM, the principle being that if you can't
compete, rebrand what you have and tell everyone it's
something new.
