RMX (operating System)
Real-time Multitasking eXecutive (iRMX) is a real-time operating system designed for use with the Intel 8080 and 8086 family of processors. Overview Intel developed iRMX in the 1970s and originally released RMX/80 in 1976 and RMX/86 in 1980 to support and create demand for their processors and Multibus system platforms. The functional specification for RMX/86 was authored by Bruce Schafer and Miles Lewitt and was completed in the summer of 1978 soon after Intel relocated the entire Multibus business from Santa Clara, California to Aloha, Oregon. Schafer and Lewitt went on to each manage one of the two teams that developed the RMX/86 product for release on schedule in 1980. Effective 2000 iRMX is supported, maintained, and licensed worldwide by TenAsys Corporation, under an exclusive licensing arrangement with Intel. iRMX is a layered design: containing a kernel, nucleus, basic I/O system, extended I/O system and human interface. An installation need include only the compon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aloha, Oregon
Aloha (, not ) is a census-designated place and unincorporated community in Washington County, Oregon, United States. By road it is west of downtown Portland. As of the 2020 Census, the population was 53,828. Fire protection and EMS services are provided through Tualatin Valley Fire and Rescueand American Medical Reaponse. and American Medical Response. History On January 9, 1912, the community received its name with the opening of a post office named Aloha; the area had previously been known as Wheeler Crossing. According to ''Oregon Geographic Names'', the origin of the name Aloha is disputed. Some sources say it was named by Robert Caples, a railroad worker, but it is unknown why the name was chosen. In 1983 Joseph H. Buck claimed that his uncle, the first postmaster, Julius Buck, named the office "Aloah" after a small resort on Lake Winnebago in Wisconsin. Supposedly the last two letters were transposed by the Post Office during the application process. The local pronunc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
REN (command)
ren (or rename) is a shell command for renaming a file and in some implementations (such as AmigaDOS) a directory. Some shells with also provide a move command that provides for moving between directories. On systems that do not support a move command (such as MS-DOS older than 6.00), the user could copy a file to a new destination and then delete the original file. In DOSBox, ren can move files. The command is in various shells such as COMMAND.COM, Command Prompt, 4DOS, 4NT and PowerShell. In MS-DOS, the command is available in versions 1 and later. In PowerShell, ren is a predefined alias for the Rename-Item Cmdlet which serves the same essential purpose. Similar commands are available in many operating systems. The command is available in the CP/M, MP/M, Cromemco DOS, TRIPOS, OS/2, ReactOS, SymbOS, and DexOS. Multics includes a rename command to rename a directory entry; which could be contracted to rn. A command which in some cases can be contracted to ren i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Path (computing)
A path (or filepath, file path, pathname, or similar) is a text string that uniquely specifies an item in a hierarchical file system. Generally, a path is composed of directory names, special directory specifiers and optionally a filename, separated by delimiting text. The delimiter varies by operating system and in theory can be anything, but popular, modern systems use slash , backslash , or colon . A path can be either relative or absolute. A relative path includes information that is relative to a particular directory whereas an absolute path indicates a location relative to the system root directory, and therefore, does not depends on context like a relative path does. Often, a relative path is relative to the working directory. For example, in command , is a relative path to the file with that name in the working directory. Paths are used extensively in computer science to represent the directory/file relationships common in modern operating systems and are essential ...

FORMAT (command)
In computing, format is a command-line utility that carries out disk formatting. It is a component of various operating systems, including 86-DOS, MS-DOS, IBM PC DOS and OS/2, Microsoft Windows and ReactOS. Overview The command performs the following actions by default on a floppy disk, hard disk drive, solid state (USB), or other magnetic medium (it will not perform these actions on optical media): # clearing the FAT entries by changing them to # clearing the FAT root directory by changing any values found to (NB.

DIR (command)
dir, short for ''directory'', is a shell (computing), shell command (computing), command for listing file system contents; computer file, files and file directory, directories. Arguably, the command provides the same essential functionality as the ls command, but typically the two commands are described as notably separate concepts, possibly since is implemented from a codebase that shares more history than many implementations. The command is often implemented as internal in the operating system shell (computing), shell instead of as a separate application as many other commands are. Implementations Although syntax, semantics and implementations vary, a command is available in the command-line interface (CLI) of the operating systems Digital Research CP/M, MP/M, Intel ISIS (operating system), ISIS-II, RMX (operating system), iRMX 86, Cromemco Cromemco DOS, CDOS, MetaComCo TRIPOS, DOS, IBM/Toshiba 4690 Operating System, 4690 OS, IBM OS/2, Microsoft Windows, Singularity (op ...

DEBUG (command)
The line-oriented debugger DEBUG.EXE is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions). DEBUG can act as an assembler, disassembler, or hex dump program allowing users to interactively examine memory contents (in assembly language, hexadecimal or ASCII), make changes, and selectively execute COM, EXE and other file types. It also has several subcommands which are used to access specific disk sectors, I/O ports and memory addresses. Overview Traditionally, all computers and operating systems have included a maintenance function, used to determine whether a program is working correctly. DEBUG was originally written by Tim Paterson to serve this purpose in 86-DOS. When Paterson began working for Microsoft in the early 1980s he brought the program with him. DEBUG was part of and has been included in MS-DOS/ PC DOS and certain versions of Microsoft Windows. Originally named DEBUG.COM, the executable was renamed i ...

DATE (command)
In computer science and computer programming, system time represents a computer system's notion of the passage of time. In this sense, ''time'' also includes the passing of days on the calendar. System time is measured by a ''system clock'', which is typically implemented as a simple count of the number of ''ticks'' that have transpired since some arbitrary starting date, called the ''epoch''. For example, Unix and POSIX-compliant systems encode system time ("Unix time") as the number of seconds elapsed since the start of the Unix epoch at 1 January 1970 00:00:00 UT, with exceptions for leap seconds. Systems that implement the 32-bit and 64-bit versions of the Windows API, such as Windows 9x and Windows NT, provide the system time as both , represented as a year/month/day/hour/minute/second/milliseconds value, and , represented as a count of the number of 100-nanosecond ticks since 1 January 1601 00:00:00 UT as reckoned in the proleptic Gregorian calendar. System time can be c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COPY (command)
copy is a shell command for copying files. Different implementations provide various capabilities, such as: * Combining (concatenating) multiple files into a single file * If multiple source files are specified before the path to an existing directory, then files are copied to the directory * Support for text vs. binary data; for text, the command stops when it reaches an end-of-file (EOF) character; for binary, files are copied in their entirety; ignoring EOF * In DOS, a file can be copied to or from a device. For example, copy ''path'' con outputs the file at ''path'' to the console, and copy con ''path'' copies text typed at the console to a file at ''path'' Implementations The command is available in RT-11, OS/8,"Concise Command Language" (CCL).

Backup
In information technology, a backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event. The verb form, referring to the process of doing so, is "wikt:back up, back up", whereas the noun and adjective form is "wikt:backup, backup". Backups can be used to data recovery, recover data after its loss from File deletion, data deletion or Data corruption, corruption, or to recover data from an earlier time. Backups provide a simple form of IT disaster recovery; however not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server. A backup system contains at least one copy of all data considered worth saving. The computer data storage, data storage requirements can be large. An information repository model may be used to provide structure to this storage. There are different types of data stor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Thread (computing)
In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. In many cases, a thread is a component of a process. The multiple threads of a given process may be executed concurrently (via multithreading capabilities), sharing resources such as memory, while different processes do not share these resources. In particular, the threads of a process share its executable code and the values of its dynamically allocated variables and non- thread-local global variables at any given time. The implementation of threads and processes differs between operating systems. History Threads made an early appearance under the name of "tasks" in IBM's batch processing operating system, OS/360, in 1967. It provided users with three available configurations of the OS/360 control system, of which Multiprogramming with a Variable Number of Tasks (MVT) ...
