Diskcopy
In computing, diskcopy is a command used on a number of operating systems for copying the complete contents of a diskette to another diskette. Implementations The command is available in MS-DOS, IBM PC DOS, DR FlexOS, IBM/Toshiba 4690 OS, MetaComCo TRIPOS, Processor Technology PTDOS, AmigaDOS, TSL PC-MOS, PTS-DOS, SISNE plus, FreeDOS, IBM OS/2, and Microsoft Windows. The MS-DOS version was originally written in August 1982. It is available in MS-DOS versions 2 and later. Digital Research DR DOS 6.0 and Datalight ROM-DOS also include an implementation of the command. The FreeDOS version was developed by Imre Leber and is licensed under the GNU GPL 2. The command is not included in Windows 10. The command is not included in Windows 11. xcopy is a like command Example *Copy the complete contents of the diskette in Drive A drive to the diskette in B drive. >diskcopy a: b: *If there is only have one diskette drive, diskcopy can be done by typing the source drive o ...

PC-MOS
PC-MOS/386 is a multi-user, multitasking computer operating system produced by The Software Link (TSL), announced at COMDEX in November 1986 for February 1987 release. PC-MOS/386, a successor to PC-MOS, can run many MS-DOS programs on the host machine or a terminal connected to it. Unlike MS-DOS, PC-MOS/386 is optimized for the Intel 80386 processor; however early versions will run on any x86 computer. PC-MOS/386 used to be proprietary, but it was released as open-source software in 2017. History The last commercial version produced was v5.01, compatible with MS-DOS 5. It required a memory management unit (MMU) to support memory protection, so was not compatible with earlier 8086 and 8088 processors. MMU support for 286-class machines was provided using a proprietary hardware shim inserted between the processor and its socket. 386 machines did not require any special hardware. Multi-user operation suffered from the limitations of the day including the inability of the pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FlexOS
FlexOS is a discontinued modular real-time multiuser multitasking operating system ( RTOS) designed for computer-integrated manufacturing, laboratory, retail and financial markets. Developed by Digital Research's Flexible Automation Business Unit in Monterey, California, in 1985. The system was considered to become a successor of Digital Research's earlier Concurrent DOS, but with a new, modular, and considerably different system architecture and portability across several processor families. Still named Concurrent DOS 68K and Concurrent DOS 286, it was renamed into FlexOS on 1 October 1986 to better differentiate the target audiences. FlexOS was licensed by several OEMs who selected it as the basis for their own operating systems like 4680 OS, 4690 OS, S5-DOS/MT and others. Unrelated to FlexOS, the original Concurrent DOS system architecture found a continuation in successors like Concurrent DOS XM and Concurrent DOS 386 as well. Overview Concurrent DOS 286, Concu ...

OS/2
OS/2 is a Proprietary software, proprietary computer operating system for x86 and PowerPC based personal computers. It was created and initially developed jointly by IBM and Microsoft, under the leadership of IBM software designer Ed Iacobucci, intended as a replacement for DOS. The first version was released in 1987. A feud between the two companies beginning in 1990 led to Microsoft’s leaving development solely to IBM, which continued development on its own. OS/2 Warp 4 in 1996 was the last major upgrade, after which IBM slowly halted the product as it failed to compete against Microsoft's Microsoft Windows, Windows; updated versions of OS/2 were released by IBM until 2001. The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's "IBM Personal System/2, Personal System/2 (PS/2)" line of second-generation PCs. OS/2 was intended as a protected mode, protected-mode successor of IBM PC DOS, PC DOS targeting t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TRIPOS
TRIPOS (''TRIvial Portable Operating System'') is a computer operating system. Development started in 1976 at the Computer Laboratory of Cambridge University and it was headed by Dr. Martin Richards. The first version appeared in January 1978 and it originally ran on a PDP-11. Later it was ported to the Computer Automation LSI4 and the Data General Nova. Work on a Motorola 68000 version started in 1981 at the University of Bath. MetaComCo acquired the rights to the 68000 version and continued development until TRIPOS was chosen by Commodore in March 1985 to form part of an operating system for their new Amiga computer; it was also used at Cambridge as part of the Cambridge Distributed Computing System. Students in the Computer Science department at Cambridge affectionately refer to TRIPOS as the ''Terribly Reliable, Incredibly Portable Operating System''. The name TRIPOS also refers to the Tripos system of undergraduate courses and examinations, which is unique to Cam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4690 Operating System
4690 Operating System (sometimes shortened to 4690 OS or 4690) is a specially designed point of sale (POS) operating system, originally sold by IBM. In 2012, IBM sold its retail business, including this product, to Toshiba, which assumed support. 4690 is widely used by IBM and Toshiba retail customers to run retail systems which run their own applications and others. Retailers have used the 4690 Operating System for their operations because of its many retail-specific and reliability features. In addition to running on IBM hardware, third-party vendors have exploited the 4690 features on competitive hardware. History 4690 is the successor product to IBM 4680 OS, which was in use by IBM customers since 1986. The original 4680 OS was based on Digital Research's Concurrent DOS 286, a system thereafter renamed to FlexOS 286 in November 1986. In July 1993, IBM adopted FlexOS version 2.32 as the basis of their 4690 OS version 1. FlexOS 2.32 supported ''286'' (Intel 80286) and ''386' ...

Command (computing)
In computing, a command is an instruction received via an external Interface (computing), interface that directs the behavior of a computer program. Commonly, commands are sent to a program via a command-line interface, a scripting language, script, a network protocol, or as an event triggered in a graphical user interface. Many commands support arguments to specify input and to modify default behavior. Terminology and syntax varies but there are notable common approaches. Typically, an option or a flag is a name (without Whitespace character, whitespace) with a prefix such as dash or Slash (punctuation), slash that modifies default behavior. An option might have a required value that follows it. Typically, flag refers to an option that does not have a following value. A parameter is an argument that specifies input to the command and its meaning is based on its position in the command line relative to other parameters; generally ignoring options. A parameter can specify anything ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-platform
Within computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several Computing platform, computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the Interpreter (computing), interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application software, application may run on Linux, macOS and Microsoft Windows. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, ArkUI-X, Kivy (framework), Kivy, Qt (software), Qt, GTK, Flutter (software), Flutter, NativeScript, Xamarin, Apache Cordova, Ionic (mobile app framework ...
