Please tell us of a term you did not find in the dictionary,
or a definition you would like to see improved.
Term to define:

W3:  World Wide Web. See Web.

W3C:  See World Wide Web Consortium.

WABI:  An attempt by Sun Microsystems to create a Windows clone under Unix. WABI works by intercepting calls from applications to the Windows API and converting them to X-Windows calls. IBM did take out a license for WABI, and announced it for AIX1 in April 1994, but withdrew it in September 1996. When WABI was announced, everyone thought that it stood for Windows application binary interface, but Sun now vigorously denies this (without saying what it does stand for – what a brilliant idea, perhaps?). However, Windows application binary interface (ABI) describes exactly what WABI does; one can only conjecture that Microsoft has got picky about this terminology. Sun finally laid WABI to rest when it announced a July 15, 1997, end of life date.

WAF:  Workfolder Application Facility. Software on the System/36 and AS/400 within the ImagePlus image processing system. WAF manages scanned documents, and creates and manages interaction with workflow software. Originally developed by IBM for Citibank’s credit card correspondence. Replaced by IBM Content Manager December 1997. cf. FAF.

WAIS:  Wide Area Information Servers based on the Z39.50 protocol for Internet-accessible databases.

Walking drives:  In the days of the pre-Winchester magnetic-disk drives, slight defects such as misaligned spindles or worn bearings could cause the devices to lurch forward. As a result these drives could gradually meander across rooms when running. This further emphasized their close evolutionary links with the Washing machine.

Wall follower:  The term wall follower is derived from a technique used in robotics to develop strategies for escaping from mazes. The wall follower doesn’t have a terribly sophisticated intelligence; it just hugs the right or left wall, and backtracks and tries something else only if it gets into a blind alley. In IBMspeak, a wall follower is someone with a penchant for blindly following rules. cf. Tree hugger.

WAN:  Wide Area Network. Generic name for a data transport mechanism which goes beyond the immediate locality, and therefore (usually) needs to conform to ITU-T standards at some level. Most SNA networks are WANs. cf. LAN, MAN.

Wang:  Wang Labs. A minicomputer and PC manufacturer which failed to turn its outstanding success in the word processor market during the 1970s into a success in the small systems and office automation market. June 1991 IBM invested $25M in the struggling Wang, and set up a deal in which Wang sold RS/6000, AS/400 and PS/2 machines as replacements for its own Wang machines. During most of the 1990s, Wang specialized in imaging and workflow software, and had alliances with a number of vendors. In 1999, the company declared bankruptcy, continued briefly as a provider of network services, then was bought by the Dutch company Getronics.

WAP:  Wireless Application Protocol. A set of security, transaction, session, application and transport layer protocols that creates end-to-end secure connections for mobile communications.

Warp:  OS/2 is fully 32-bit, and differs from earlier implementations particularly by being Internet-ready (i.e., incorporating TCP/IP, ftp2, telnet, and Gopher) and optimized for multimedia applications. It’s also finely wrought and visually elegant... and a pleasure to use. The campaign launching Warp was one of IBM’s most aggressive, with loads of knocking copy addressed at PC-DOS/Windows users – lemmings marching forward to adopt the world’s first 32-bit OS based on a 16-bit OS modeled on an eight-bit OS, etc. There were even demonstrations of OS/2 running Windows 3.1 applications faster than Windows 3.1 itself.

Warp Connect:  Version of Warp announced May 1995 to compete with Windows for Workgroups. Includes built-in requesters for LAN Server and NetWare, peer-to-peer and TCP/IP networking, productivity software, and Web browser. Withdrawn August 1999, with service already ended in September 1997, with OS/2 Warp Version 4 listed as its replacement.

Warp Server:  All-singing, all-dancing network operating system announced mid 1995 which combines LAN Server 4.0 with OS/2 Warp. It’s backward-compatible with previous IBM LAN Server clients. Supports gateway functionality to NetWare and Microsoft servers by allowing OS/2 Warp Server clients to access non-OS/2 Warp Server resources.

WASE:  Workstation Aided Software Engineering (sometimes Workstation Application Support Environment). A loose agglomeration of products, now defunct, which was designed to provide a CASE1 environment on a PC. WASE was not a terribly important product – most IBM offices never got to hear of it!

WASEF:  When America Surfs, Europe Freezes. Not a weather warning; rather a handy mnemonic for hapless Europeans who attempt to access the Internet via a dial-up connection after 12.00 GMT.

Washing machine:  Old-style (pre-Winchester) 14 inch hard disks in floor-standing cabinets. So called because of the large size of the cabinet and the top-loading access to the media packs which were set on a spin cycle. See also walking drives.

Water cooler:  The water cooler has two quite distinct meanings in IBM culture. Firstly, users of large IBM mainframes need one to stop their machines overheating. Secondly the water cooler, along with the coffee machine, is a forum for exchange of ideas and gossip in IBM offices. John Akers’ famous directive to his staff, Stop standing round the water cooler, was understandably interpreted in different ways. Many account managers, following the first definition, believed Akers was telling them to abandon mainframes and start selling Unix workstations instead; demoralized by the anticipated lack of commission, they immediately opted for early retirement. See Water MIPS.

Water MIPS:  Industry speak for large, water-cooled computers of traditional mainframe type.

WaveRunner:  Family of IBM ISDN adapter products. July 1996, IBM sold the name, inventory, and other rights to Network Express Inc.

WBEM:  Web-Based Enterprise Management. See DMTF.

WBI:  See Web Browser Intelligence.

WCA:  See WebSphere Commerce Analyzer.

WCS1:  Writable Control Storage.

WCS2:  See WebSphere Commerce Suite.

WDSF:  See Workstation Data Save Facility.

Web:  World Wide Web (WWW). But everyone just says Web. A loose, but constantly growing, collection of Internet servers, located worldwide, which support multimedia pages of text, graphics, sound, and video. Originally developed by the CERN particle physics laboratories in Switzerland, the Web’s commercial success in the mid 1990s was due mainly to the widespread availability of graphical front-ends known as browsers, which interpret HTML and allow the user to navigate easily from one site or page to another. The Web has been integrated with other Internet services, such as e-mail and file transfer. In early 1996 IBM decided that the Web was enormously important and announced products for just about every system it sells. See also HTML, HTTP, Internet Explorer, Netscape, WebExplorer.

Web.Data:  A comprehensive architecture from IBM that promised to encompass all of the function of DB2 WWW while delivering additional benefits such as improved performance, access to ODBC data etc. Announced July 1996 along with a beta program for the OS/2, AIX1, and Windows NT versions of this product. These days, no one, seemingly not even at IBM, even remembers that Web.Data or DB2 WWW ever existed.

Web application:  A traditional computer application that runs on a Web server. Instead of a workstation GUI or host terminal screen, a Web page is seen by the user through a Web browser. See also Web application server.

Web application server:  An application server that is linked to a Web server. When the Web server receives an HTTP request that requires computation or other resources, it passes the request to the Web application server for processing.

Web browser:  Software that runs on a workstation whose main purpose is to translate the HTML it receives into the Web page it represents. Netscape and Microsoft Internet Explorer dominate the market, though the word market is probably inappropriate for the free products that both are. Beyond HTML translation, Web browser functionality has expanded greatly, especially with the addition of plug-ins. Even without plug-ins, Web browsers have built-in Java Virtual Machines and ftp2 support.

Web Browser Intelligence:  WBI or, in its more sickening form, Webby. IBM intelligent agent technology implemented on the client system rather than on the server. WBI is built as a generalized proxy server, but with plug-in intelligence and is suited as a general base for Internet applications. It is powered by intelligent agent user modeling technology from IBM’s Almaden Research Lab.

WebExplorer:  Web browser, built into OS/2 Warp.

Weblicator:  Allows browser users to selectively pre-fetch Web pages, search, categorize and work on them off-line and automatically update changes. From Lotus. Replaced by newer technologies including Lotus iNotes and Domino Offline Services (DOLS).

Web page:  A single HTML file which the user sees as a single scrollable entity within a Web browser, not requiring clicking on any hypertext links to see all of it.

Web server:  The computer system that responds to http:// requests from a Web browser, delivering the Web page requested by the http:// URL.

WebServer/400:  Web server software from International Marketing Strategies. Used by IBM in an AS/400 Web server package in May 1996.

Web Services Inspection:  See WS-Inspection.

Web site:  A home page and associated Web pages where the home page has a URL of the form without a / and additional characters following.

White Space:  Excess computer capacity reserved, but not used or paid for, by IBM customers under Workload License Charges (WLC) agreements.

Whitewater:  IBM plan to develop DB2 accounting software. The plug was pulled on the project early 1989 after it got in a mess and IBM’s pleas for help fell on the deaf ears of companies with which Whitewater was meant to compete.

WIBNI:  Wouldn’t It Be Nice If...

WIDL:  Web Interface Definition Language. Devised by WebMethods and submitted to W3C. Its purpose is to enable automation of Web interactions with HTML/XML documents and forms. WIDL definitions provide a mapping between Web resources and applications written in conventional programming languages. Disappeared due to lack of interest and industry acceptance.

Wildcard:  A search specification where certain characters may have multiple values. The question mark ? often matches any character, so S?T would match SET, SAT, SIT, S-T, etc. The asterisk * is the other common wildcard character, referring to zero or more characters. As well as the values shown for question mark, S*T would match SOFT, ST, SSSSSSSSSSSSSSSTTTTTTTTT, etc.

WIMP:  Alternate form of WIMPS.

WIMPS:  Windows, Icons, Mouse, Pointer, Scroll bars. The P may also be used for Pull-down or Pop-up menus. Also seen without the S: WIMP. Generic name for systems which use windows, icons, mouse or similar pointing device, and the other things listed and normally associated with a GUI. The term no doubt came into popular use on the basis that real men don’t use mice. See also icon1.

Win32:  The API to 32-bit Windows.

Winchester:  IBM name for a 1973 vintage disk drive, and a generic name for any hard disk. There are two explanations for the name: the first says it’s because the Winchester was developed near Winchester in the UK, where IBM has some research labs; the second says it’s named after the well-known .30-.30 rifle because the first Winchester device held 30MB on each of its two spindles. You pays your money, and you takes your choice!

Windows:  PC software which started life as an add-on to PC-DOS that provided a GUI and allowed a PC to run multiple concurrent PC-DOS sessions. The success of Windows 3.0 was instrumental in Microsoft’s abandonment of OS/2 and all the resulting traumas in the IBM-Microsoft relationship. Beginning in the mid 1990s with Windows NT and Windows 95, it became a full blown operating system without PC-DOS, though Windows 95 was tied very closely to PC-DOS to ensure compatibility. Windows 98 and Me followed 95, dead ending the DOS heritage. Both Windows Me and Windows 2000, which replaced NT, were replaced by Windows XP, a new version of Windows 2000. The Windows server operating systems are Windows 2002.

Windows 2000:  The workstation (Professional) and various server versions of the Microsoft operating system that was promised for years as Windows NT Version 5.0. Replaced NT 4 and replaced by Windows XP on the workstation and Windows 2002 Server.

Windows 2002:  The server operating systems that replaced Windows 2000. The workstation (client) operating system is Windows XP.

Windows 95:  Windows 4.0, a true 32-bit version of Microsoft’s original Windows 3.x. Originally expected to go on general release at the end of 1994 or early 1995, but began to slip to around the middle of 1995, and ever onward. It eventually emerged on 24 August 1995 amid squirmingly embarrassing stunts and puffs. Prior to September 1994, it was called Chicago. See also Pegasus2.

Windows 98:  Microsoft Windows operating system replacing Windows 95 and replaced by Windows Me.

Windows CE:  A lite version of Windows 95 designed exclusively for pocket-sized, hand-held devices. It comes with scaled down versions of MS Word and Excel, and allows migration of files back and forth between a CE device and a PC. Based on the Win32 API set.

Windows Connection:  IBM product providing 3270/5250 emulation under Windows. IBM sees it as a migration path to OS/2. Enhanced version announced September 1990. Withdrawn April 1993.

Windows for Workgroups:  Announced October 1992. Integrated networking and workgroup functionality within Windows 3.1. The product supports electronic mail, group meetings, shared files and printers, shared calendars, and collaborative projects. It can provide networking capabilities on its own, or it can be used as a client on an existing local area network. Version 3.11 had improved support for Novell NetWare and Windows NT, I/O performance gains of more than 100 percent, and new capabilities for mobile computing such as remote access and built-in fax capabilities.

Windows Me:  Windows Millennium Edition. Microsoft Windows operating system replacing Windows 98 and replaced by Windows XP Home Edition.

Windows NT:  New Technology. Microsoft’s operating system – essentially a derivative of PC-DOS and Windows – offering pre-emptive multi-tasking and multithreading, OLE, DDE, etc, in a portable 32-bit environment. After years of pre-announcement, NT finally appeared in May 1993 in server and client versions, and was vigorously promoted by Microsoft as a server – rather than a desktop – environment. By early 1995, Microsoft claimed to have 25% of the server market, and by early 1996 it was giving Unix a run for its money. May 1996, IBM announced software which would allow NT applications to run on an z/OS mainframe. Version 5.0 was renamed Windows 2000 prior to release in February 2000. See also Cairo.

Windows XP:  The replacement for both Windows Me/98/95 and Windows 2000/NT on the workstation (client). The server operating systems were renamed Windows 2002. See also Windows NT.

WindowTool/400:  AS/400 software that enables you to create window-like interfaces on AS/400 dumb terminals. Obsolete.

Wireless Application Protocol:  See WAP.

Wireless LAN:  See 2480.

Wireless Transport Layer Security:  See WTLS.

Withdrawn:  Marketing Withdrawn. In IBMspeak, and in this glossary, the date after which IBM would no longer sell you the product. Another important date is Service Discontinued in IBMspeak: the date after which IBM will not help you with the product and/or fix it. In this glossary, support ended is used instead of Service Discontinued.

WITT:  Workstation Interactive Test Tool. OS/2 development tool that automatically records and replays interactive application test sessions. Supports OS/2 on the client, and z/OS, z/VM, VSE/ESA and OS/400 on the application server. Announced in September 1989. The X/WITT version supports AIXWindows clients. Replaced by VisualAge for COBOL Test for OS/2 October 1996.

Wizard:  GUI-based software that asks you a few questions, often just confirming the default values, then performs a systems management function, typically installing software.

Wizard adapter:  A PS/2 co-processor board which off-loaded compute-intensive tasks from a PS/2’s processor, freeing it to service the voracious demands of OS/2 or (from January 1991) AIX1. Obsolete.

WLC:  See Workload License Charges.

WLFS/VM:  See Workstation LAN File Services/VM.

WLM:  WorkLoad Manager. Feature within z/OS SRM and AIX1 for managing system resources. Users define performance goals and assign priority to each. The system then apportions resources, such as CPU and storage, according to those priorities. In z/OS, collaborates with Intelligent Resource Director.

WLR:  WorkLoad Router. IMS1 software which operates with IMS TM to provide transparent routing or balancing of a workload across a Parallel Sysplex. Announced May 1996.

WML:  Wireless Mark-up Language. A cross between XML and HTML, used with WAP, to describe the format and content of data exchanged with wireless devices.

WOM:  Web Object Management. Technology for creating, managing, and hosting content on both internal and external Web sites, often for high volume electronic commerce. A high profile use of WOM was at the 1996 Olympic games where WOM handled 188 million hits in 17 days – at the time the highest traffic ever experienced at a Web site.

WordPerfect:  PC word processing software from the WordPerfect Corp originally recommended by IBM for PS/2s connected to the AS/400 – IBM provided software to turn the AS/400 into a file server for networks of PS/2s running WordPerfect. WordPerfect was purchased by Novell and then Corel. Barely surviving today against Microsoft Word.

WordPerfect/370:  Text and word processing mainframe software at one time sold by the WordPerfect Corporation.

WordPerfect Corporation:  Software vendor specializing in word processing software, mainly on the PC although it has versions of its software on the AS/400 and mainframe too. Claimed to have two thirds of the US word processing market in 1992. June 1993, the company merged with Novell, and about two and a half years later all the products were sold to Corel.

WordPro:  New name for Lotus AmiPro.

Workflow:  Generic name for the type of software which manages the flow of work – typically some kind of paper processing activity – through a system by providing computer support for tasks with a large human and/or manual component. The most widespread use of workflow software is in image processing systems such as IBM’s ImagePlus where the computer system is used to progress a document through the various people in the organization who need to work on it. See also MQSeries Workflow.

Workframe/2:  OS/2 project-oriented development environment. Presentation Manager-based, and has an open interface which allows IBM or third-party editors, compilers, and debuggers to be connected. Replaced by VisualAge C++ for OS/2 September 1995.

WorkGroup:  A portfolio of capabilities announced by IBM in November 1994. It provides group communications, information management, and work management within e-mail systems – including multimedia mail transfer, directory, scheduling and calendaring services, and access to OfficeVision systems. Much of the functionality is built on a backbone of the MQSeries messaging software. Withdrawn November 1996.

Working set:  The section (or sections) of a mainframe program where processing is concentrated. In paging systems the size of the working set determines the (approximate) main-storage requirements for the program.

Workload License Charges:  A software licensing charge by required software capacity, not hardware capacity.

WorkLoad Manager:  see WLM.

Workload Router:  See WLR.

WorkPad:  A pocket-sized PDA from IBM that exploits 3Com’s PalmPilot technology. It signaled the end of IBM’s efforts to produce a viable PDA of its own. Announced September 1997. See 8602, 2608, Simon.

Workplace:  A term variously used to refer to the IBM Microkernel and to an architecture/initiative/set of standards to develop a common software base across all IBM platforms. The term was abandoned March 1995 and replaced by the IBM microkernel when it refers to the core operating system based on Mach, and by – well, nothing, really – when it refers to the set of standards.

Workplace microkernel:  An early name for what is now called the IBM microkernel.

Workplace OS:  The original name for what is now known as the IBM microkernel.

Workplace Shell:  The user interface paradigm for OS/2 EE based on CUA 91. Implemented in OS/2 Version 2.0 as a multi-tasking, object-oriented replacement for Presentation Manager. It was much more like Unix front-ends than its PM forebears. The name was dropped in early 1995.

Works as designed:  A positive description of a design bug – usually corrected by a change to the documentation, which then reflects how the program actually works rather than how it should function.

Workspace datasets:  VSAM datasets used by RACF for queuing requests between RRSF nodes.

WorkSpace On-Demand:  IBM’s Intel-based network operating system, optimized for network computing. Released November 1997. Supports both Windows and OS/2 clients. See Bluebird.

Workstation Data Save Facility:  SystemView facility which allows a z/VM host to act as a workstation server to enable users to backup, archive, and restore workstation files. Replaced by ADSM in April 1993.

Workstation Interactive Test Tool:  See WITT.

Workstation LAN File Services/VM:  May 1992 z/VM software providing workstation data storage and access facilities. Effectively turns a z/VM machine into a whopping great file server. Replaced June 1993 by LAN File Services/ESA.

Workstation One:  Family of emulation programs designed to provide a consistent interface in a number of workstation environments, including OS/2, Windows, Macintosh, and AIX. Announced January 1993. Withdrawn February 1994. The product family really was The Wollongong Group’s (TWG) Pathway Access and IBM customers were given the option of a license for the equivalent TWG product.

World Avenue:  IBM’s US on-line shopping mall which was launched with great fanfare in June 1996 and shut in July 1997. Poor sales figures which have plagued on-line malls were a primary factor in its downfall.

World Wide Web:  See Web.

World Wide Web Consortium:  The loose affiliation of bodies which define Internet standards.

WORM1:  Write Once Read Many. Generic term for storage devices (e.g., the majority of optical storage systems today) used as permanent repositories of data. CD-ROM is the most widely known WORM device, although most end-user models are read only – the vendor does the writing. IBM offers the 3363, 9246/7, and 3995 WORM drives. An optical WORM medium is also used in the mainframe process controller for software updates. The term WORM is also used in a specific technical sense to refer to user recordable optical storage media and standards from ANSI committee X3B11.

Worm2:  A virus that creates multiple versions of itself in a computer’s memory, effectively forcing other programs out.

WOSA:  Windows Open Services Architecture. A set of APIs for the Windows environment to enable Windows applications to talk to other systems across a network (notably to a mainframe using SNA). WOSA was developed by a consortium of 20 vendors headed by Microsoft. IBM was a member, although initially it rather sniffily said that WOSA won’t be able to do much that you can’t already do from OS/2 anyway. By the mid 1990s, WOSA had created MAPI, SAPI, TAPI, among other standards.

WRC:  Workstation Resource Center. Another one of those IBM concepts (cf. Information Center) in which IBM proposes ways in which the customer can organize his data center (which is another example) in ways which simplify the task of IBM’s sales force. The WRC provides IBM with a single reference point for selling workstation and communications products. Less cynically, it provides the user organization with a pool of expertise on workstation management. Long forgotten.

Write ring:  See tape ring.

Writing Pad:  A rudimentary but adequate word processor originally supplied with OfficeVision/2.

WRK:  Data format used by Lotus Symphony. Used as a data interchange format for PCs.

WSA:  See Tivoli Web Services Analyzer.
