VP-Info
VP-Info is a database language and compiler for the personal computer. VP-Info was a competitor to the Clipper and dBase applications in the late 1980s and 1990s. VP-Info was originally intended to run on MS-DOS, DR-DOS and the PC-MOS/386 operating system, but now is run on the vDOS,vDOS: https://www.vdos.info/ or DOSbox-X, emulators. The last release of VP-Info, a multi-tasking, multi-user version released in 1992 with a built-in compiler, and was named SharkBase, or simply "Shark". Origin In the early 1980s, David Clark met George Gratzer, a mathematics professor at the University of Manitoba, at ComputerLand in Winnipeg where Gratzer was looking for someone who could program in dBase. Clark had been using dBase II, but was frustrated by its limitations for reporting on more than 2 tables at a time. While working for Standard Knitting (a client of Gratzer's and Clark's), David wrote a report generator called ''dComp'' that would allow up to six related data files to be in ...

DBase II
dBase (also stylized dBASE) was one of the first database management systems for microcomputers and the most successful in its day. The dBase system included the core database engine, a query system, a forms engine, and a programming language that tied all of these components together. Originally released as Vulcan for PTDOS in 1978, the CP/M port caught the attention of Ashton-Tate in 1980. They licensed it, re-released it as dBASE II, and later ported it to IBM PC computers running DOS. On the PC platform in particular, dBase became one of the best-selling software titles for a number of years. A major upgrade was released as dBase III and ported to a wider variety of platforms, including UNIX and VMS. By the mid-1980s, Ashton-Tate was one of the "big three" software publishers in the early business-software market, along with Lotus Development and WordPerfect. Starting in the mid-1980s, several companies produced their own variations on the dBase product and especial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paperback Software International
Paperback Software International Ltd. was a software company founded in 1983 by Adam Osborne to manufacture discount software such as word processor Paperback Writer and related spell checker Paperback Speller, spreadsheet VP-Planner, database VP-Info, and the VP-Expert artificial intelligence software. VP-Expert was developed by Brian Sawyer The company was headquartered in Berkeley, California. History The company was found by a United States court to have infringed on copyright for reproducing the appearance and menu system of Lotus 1-2-3 in its competing spreadsheet program, even though they did use different source code. The loss of this lawsuit was the main cause for the foundering of the company and paved the way for future copyright law on computer software. Overview Not only was VP Planner cheaper, it was regarded by some as better. Adam Osborne's US Paperback Software business folded following lengthy litigation with Lotus Software.

Paperback Software International Ltd
A paperback (softcover, softback) book is one with a thick paper or paperboard cover, also known as wrappers, and often held together with glue rather than stitches or staples. In contrast, hardback (hardcover) books are bound with cardboard covered with cloth, leather, paper, or plastic. Inexpensive books bound in paper have existed since at least the 19th century in such forms as pamphlets, yellowbacks and dime novels. Modern paperbacks can be differentiated from one another by size. In the United States, there are "mass-market paperbacks" and larger, more durable "trade paperbacks". In the United Kingdom, there are A-format, B-format, and the largest C-format sizes. Paperback editions of books are issued when a publisher decides to release a book in a low-cost format. Lower-quality paper, glued (rather than stapled or sewn) bindings, and the lack of a hard cover may contribute to the lower cost of paperbacks. In the early days of modern paperbacks, the 1930s and 1940s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Area Network
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, and has its network equipment and interconnects locally managed. LANs facilitate the distribution of data and sharing network devices, such as printers. The LAN contrasts the wide area network (WAN), which not only covers a larger geographic distance, but also generally involves Leased line, leased telecommunication circuits or Internet links. An even greater contrast is the Internet, which is a system of globally connected business and personal computers. Ethernet and Wi-Fi are the two most common technologies used for local area networks; historical network technologies include ARCNET, Token Ring, and LocalTalk. Cabling Most wired network infrastructures utilize Category 5 cable, Category 5 or Category 6 cable, Category 6 twisted pair cabling with RJ45 (telecommunications), RJ45 compatible terminations. This medium provides physical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TCP/IP
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). Early versions of this networking model were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to highest, the layers are the li ...

NetBIOS
NetBIOS () is an acronym for Network Basic Input/Output System. It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol. Operating systems of the 1980s (DOS and Novell Netware primarily) ran NetBIOS over IEEE 802.2 and IPX/SPX using the NetBIOS Frames (NBF) and NetBIOS over IPX/SPX (NBX) protocols, respectively. In modern networks, NetBIOS normally runs over TCP/IP via the NetBIOS over TCP/IP (NBT) protocol. NetBIOS is also used for identifying system names in TCP/IP (Windows). History and terminology NetBIOS is an operating system-level API that allows applications on computers to communicate with one another over a local area network (LAN). The API was created in 1983 by Sytek Inc. for software communication over IBM PC Network LAN technology. On IBM PC Network, as an API alone, NetBIOS relied on proprietary Sytek ...

DOSBox
DOSBox is a free and open-source MS-DOS emulator. It supports running programs primarily video games that are otherwise inaccessible since hardware for running a compatible disk operating system (DOS) is obsolete and generally unavailable today. It was first released in 2002, when DOS technology was becoming obsolete. Its adoption for running DOS games is relatively widespread; partially driven by its use in commercial re-releases of games. Development Before Windows XP, consumer-oriented versions of Windows were based on MS-DOS. Windows 3.0 and its updates were operating environments that ran on top of MS-DOS, and the Windows 9x series consisted of operating systems that were still based on MS-DOS. These versions of Windows could run DOS applications. Conversely, the Windows NT operating systems were not based on DOS. A member of the series, Windows XP, debuted on October 25, 2001, and became the first consumer-oriented version of Windows to not use DOS. Althou ...

Emulator
In computing, an emulator is Computer hardware, hardware or software that enables one computer system (called the ''host'') to behave like another computer system (called the ''guest''). An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate (or imitate) another program or device. Many printer (computing), printers, for example, are designed to emulate Hewlett-Packard, HP LaserJet printers because a significant amount of software is written specifically for HP models. If a non-HP printer emulates an HP printer, any software designed for an actual HP printer will also function on the non-HP device, producing equivalent print results. Since at least the 1990s, many video game enthusiasts and hobbyists have used emulators to play classic arcade games from the 1980s using the games' original 1980s machine code and data, which is in ...

Lotus 1-2-3
Lotus 1-2-3 is a discontinued spreadsheet program from Lotus Software (later part of IBM). It was the first killer application of the IBM PC, was hugely popular in the 1980s, and significantly contributed to the success of IBM PC-compatibles in the business market. The first spreadsheet, VisiCalc, had helped launch the Apple II as one of the earliest personal computers in business use. With IBM's entry into the market, VisiCalc was slow to respond, and when they did, they launched what was essentially a straight port of their existing system despite the greatly expanded hardware capabilities. Lotus's solution was marketed as a three-in-one integrated solution: it handled spreadsheet calculations, database functionality, and graphical charts, hence the name "1-2-3", though how much database capability the product actually had was debatable, given the sparse memory left over after launching 1-2-3. It quickly overtook VisiCalc, as well as Multiplan and SuperCalc, the two Visi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
