The traditional Mongolian script , also known as the Hudum Mongol bichig , was the first writing system created specifically for the Mongolian language , and was the most widespread until the introduction of Cyrillic in 1946. It is traditionally written in vertical lines Top-Down, right across the page. Derived from the Old Uyghur alphabet , it is a true alphabet , with separate letters for consonants and vowels. It has been adapted for such languages as Oirat and Manchu . Alphabets based on this classical vertical script continue to be used in Mongolia and Inner Mongolia to write Mongolian, Xibe and, experimentally, Evenki .
74-560: Computer operating systems have been slow to adopt support for the Mongolian script; almost all have incomplete support or other text rendering difficulties. The Mongolian vertical script developed as an adaptation of the Old Uyghur alphabet for the Mongolian language. Tata-tonga , a 13th-century Uyghur scribe captured by Genghis Khan , was responsible for bringing the Old Uyghur alphabet to
148-493: A or e ( ᠠ ‑a/‑e ) is common, and can appear at the end of a word stem , or suffix . This form requires a final-shaped preceding letter, and an word-internal gap in between. This gap can be transliterated with a hyphen. The presence or lack of a separated a or e can also indicate differences in meaning between different words (compare ᠬᠠᠷᠠ qar‑a 'black' with ᠬᠠᠷᠠ qara 'to look'). It has

When the device finishes writing, the device will interrupt the currently running process by asserting an interrupt request . The device will also place an integer onto the data bus. Upon accepting
296-645: A computer even if they are not compatible with the base operating system. A library operating system (libOS) is one in which the services that a typical operating system provides, such as networking, are provided in the form of libraries and composed with a single application and configuration code to construct a unikernel : a specialized (only the absolute necessary pieces of code are extracted from libraries and bound together ), single address space , machine image that can be deployed to cloud or embedded environments. The operating system code and application code are not executed in separated protection domains (there
370-571: A development of MULTICS for a single user. Because UNIX's source code was available, it became the basis of other, incompatible operating systems, of which the most successful were AT&T 's System V and the University of California 's Berkeley Software Distribution (BSD). To increase compatibility, the IEEE released the POSIX standard for operating system application programming interfaces (APIs), which

Only in a late form can a definite order of signs be established for the alphabet, but can likely be traced back to an earlier Uyghur model. ᠠ᠋ ᠡ᠋ ᠥ ᠦ ᠨ᠋ ᠨ [REDACTED] [REDACTED] k [REDACTED] ᠭ᠋ [REDACTED] ᠭ [REDACTED] g ᠳ᠋ In 1587,
518-484: A large legal settlement was paid. In the twenty-first century, Windows continues to be popular on personal computers but has less market share of servers. UNIX operating systems, especially Linux, are the most popular on enterprise systems and servers but are also used on mobile devices and many other computer systems. On mobile devices, Symbian OS was dominant at first, being usurped by BlackBerry OS (introduced 2002) and iOS for iPhones (from 2007). Later on,
592-442: A library with no protection between applications, such as eCos . A hypervisor is an operating system that runs a virtual machine . The virtual machine is unaware that it is an application and operates as if it had its own hardware. Virtual machines can be paused, saved, and resumed, making them useful for operating systems research, development, and debugging. They also enhance portability by enabling applications to be run on
666-447: A malformed machine instruction . However, the most common error conditions are division by zero and accessing an invalid memory address . Users can send messages to the kernel to modify the behavior of a currently running process. For example, in the command-line environment , pressing the interrupt character (usually Control-C ) might terminate the currently running process. To generate software interrupts for x86 CPUs,
740-455: A particular application's memory is stored, or even whether or not it has been allocated yet. In modern operating systems, memory which is accessed less frequently can be temporarily stored on a disk or other media to make that space available for use by other programs. This is called swapping , as an area of memory can be used by multiple programs, and what that memory area contains can be swapped or exchanged on demand. Virtual memory provides
814-503: A program does not interfere with memory already in use by another program. Since programs time share, each program must have independent access to memory. Cooperative memory management, used by many early operating systems, assumes that all programs make voluntary use of the kernel 's memory manager, and do not exceed their allocated memory. This system of memory management is almost never seen any more, since programs often contain bugs which can cause them to exceed their allocated memory. If
SECTION 10
#1732856139534888-408: A program fails, it may cause memory used by one or more other programs to be affected or overwritten. Malicious programs or viruses may purposefully alter another program's memory, or may affect the operation of the operating system itself. With cooperative memory management, it takes only one misbehaved program to crash the system. Memory protection enables the kernel to limit a process' access to
962-440: A program tries to access memory that is not accessible memory, but nonetheless has been allocated to it, the kernel is interrupted (see § Memory management ) . This kind of interrupt is typically a page fault . When the kernel detects a page fault it generally adjusts the virtual memory range of the program which triggered it, granting it access to the memory requested. This gives the kernel discretionary power over where
1036-544: A reader who knows the orthography. Letters have different forms depending on their position in a word: initial, medial, or final. In some cases, additional graphic variants are selected for visual harmony with the subsequent character. The rules for writing below apply specifically for the Mongolian language, unless stated otherwise. Mongolian vowel harmony separates the vowels of words into three groups – two mutually exclusive and one neutral: Any Mongolian word can contain
1110-467: A significant amount of CPU time. Direct memory access (DMA) is an architecture feature to allow devices to bypass the CPU and access main memory directly. (Separate from the architecture, a device may perform direct memory access to and from main memory either directly or via a bus.) When a computer user types a key on the keyboard, typically the character appears immediately on the screen. Likewise, when
1184-402: A specific moment in time. Hard real-time systems require exact timing and are common in manufacturing , avionics , military, and other similar uses. With soft real-time systems, the occasional missed event is acceptable; this category often includes audio or multimedia systems, as well as smartphones. In order for hard real-time systems be sufficiently exact in their timing, often they are just

Such single-letter vowel suffixes appear with the final-shaped forms of a / e , i , or u / ü , as in ᠭᠠᠵᠠᠷ ᠠ [γaǰar‑a] Error: {{Transliteration}}: transliteration text not Latin script ( help ) 'to the country' and ᠡᠳᠦᠷ ᠡ edür‑e 'on the day', or ᠤᠯᠤᠰ ᠢ ulus‑i 'the state' etc. Multi-letter suffixes most often start with an initial- (consonants), medial- (vowels), or variant-shaped form. Medial-shaped u in
1332-417: A user moves a mouse , the cursor immediately moves across the screen. Each keystroke and mouse movement generates an interrupt called Interrupt-driven I/O . An interrupt-driven I/O occurs when a process causes an interrupt for every character or word transmitted. Devices such as hard disk drives , solid-state drives , and magnetic tape drives can transfer data at a rate high enough that interrupting
1406-453: A variation of the classic reader/writer problem . The writer receives a pipe from the shell for its output to be sent to the reader's input stream. The command-line syntax is alpha | bravo . alpha will write to the pipe when its computation is ready and then sleep in the wait queue. bravo will then be moved to the ready queue and soon will read from its input stream. The kernel will generate software interrupts to coordinate
1480-562: Is remote direct memory access , which enables each CPU to access memory belonging to other CPUs. Multicomputer operating systems often support remote procedure calls where a CPU can call a procedure on another CPU, or distributed shared memory , in which the operating system uses virtualization to generate shared memory that does not physically exist. A distributed system is a group of distinct, networked computers—each of which might have their own operating system and file system. Unlike multicomputers, they may be dispersed anywhere in
1554-428: Is system software that manages computer hardware and software resources, and provides common services for computer programs . Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time , mass storage , peripherals, and other resources. For hardware functions such as input and output and memory allocation ,

#17328561395341628-484: Is a change away from the currently running process. Similarly, both hardware and software interrupts execute an interrupt service routine . Software interrupts may be normally occurring events. It is expected that a time slice will occur, so the kernel will have to perform a context switch . A computer program may set a timer to go off after a few seconds in case too much data causes an algorithm to take too long. Software interrupts may be error conditions, such as
1702-422: Is difficult to define, but has been called "the layer of software that manages a computer's resources for its users and their applications ". Operating systems include the software that is always running, called a kernel —but can include other software as well. The two other types of programs that can run on a computer are system programs —which are associated with the operating system, but may not be part of
1776-451: Is one among Oirat Clear , Manchu , and Buryat are the only known vertical scripts written from left to right. This developed because the Uyghurs rotated their Sogdian -derived script, originally written right to left, 90 degrees counterclockwise to emulate Chinese writing, but without changing the relative orientation of the letters. The reed pen was the writing instrument of choice until
1850-443: Is only a single application running, at least conceptually, so there is no need to prevent interference between applications) and OS services are accessed via simple library calls (potentially inlining them based on compiler thresholds), without the usual overhead of context switches , in a way similarly to embedded and real-time OSes. Note that this overhead is not negligible: to the direct cost of mode switching it's necessary to add
1924-412: Is somewhat comparable to the situation of English , which must represent ten or more vowels with only five letters and uses the digraph th for two distinct sounds. Ambiguity is sometimes prevented by context, as the requirements of vowel harmony and syllable sequence usually indicate the correct sound. Moreover, as there are few words with an exactly identical spelling, actual ambiguities are rare for
1998-499: Is supported by most UNIX systems. MINIX was a stripped-down version of UNIX, developed in 1987 for educational uses, that inspired the commercially available, free software Linux . Since 2008, MINIX is used in controllers of most Intel microchips , while Linux is widespread in data centers and Android smartphones. The invention of large scale integration enabled the production of personal computers (initially called microcomputers ) from around 1980. For around five years,
2072-473: Is that they do not load user-installed software. Consequently, they do not need protection between different applications, enabling simpler designs. Very small operating systems might run in less than 10 kilobytes , and the smallest are for smart cards . Examples include Embedded Linux , QNX , VxWorks , and the extra-small systems RIOT and TinyOS . A real-time operating system is an operating system that guarantees to process events or data by or at
2146-435: Is the part of the operating system that provides protection between different applications and users. This protection is key to improving reliability by keeping errors isolated to one program, as well as security by limiting the power of malicious software and protecting private data, and ensuring that one program cannot monopolize the computer's resources. Most operating systems have two modes of operation: in user mode ,
2220-535: The CP/M (Control Program for Microcomputers) was the most popular operating system for microcomputers. Later, IBM bought the DOS (Disk Operating System) from Microsoft . After modifications requested by IBM, the resulting system was called MS-DOS (MicroSoft Disk Operating System) and was widely used on IBM microcomputers. Later versions increased their sophistication, in part by borrowing features from UNIX. Apple 's Macintosh

2368-533: The Clear script ( Todo 'exact'), is the original form of the Mongolian script used to write the Mongolian language . It does not distinguish several vowels ( o / u , ö / ü , final a / e ) and consonants (syllable-initial t / d and k / g , sometimes ǰ / y ) that were not required for Uyghur , which was the source of the Mongol (or Uyghur-Mongol) script. The result

From the seventh and eighth to the fifteenth and sixteenth centuries, the Mongolian language separated into southern, eastern and western dialects. The principal documents from the period of the Middle Mongol language are: in the eastern dialect, the famous text The Secret History of the Mongols , monuments in the Square script , materials of

2738-498: The personal computer market, as of September 2024 , Microsoft Windows holds a dominant market share of around 73%. macOS by Apple Inc. is in second place (15%), Linux is in third place (5%), and ChromeOS is in fourth place (2%). In the mobile sector (including smartphones and tablets ), as of September 2023 , Android's share is 68.92%, followed by Apple's iOS and iPadOS with 30.42%, and other operating systems with .66%. Linux distributions are dominant in

These still needed professional operators who manually do what a modern operating system would do, such as scheduling programs to run, but mainframes still had rudimentary operating systems such as Fortran Monitor System (FMS) and IBSYS . In the 1960s, IBM introduced the first series of intercompatible computers ( System/360 ). All of them ran

Ink used was black or cinnabar red, and written with on birch bark , paper, cloths made of silk or cotton, and wooden or silver plates. Mongols learned their script as a syllabary , dividing the syllables into twelve different classes, based on
2960-410: The CPU for every byte or word transferred, and having the CPU transfer the byte or word between the device and memory, would require too much CPU time. Data is, instead, transferred between the device and memory independently of the CPU by hardware such as a channel or a direct memory access controller; an interrupt is delivered only when all the data is transferred. If a computer program executes

This is called a segmentation violation or Seg-V for short, and since it is both difficult to assign a meaningful result to such an operation, and because it is usually a sign of a misbehaving program, the kernel generally resorts to terminating the offending program, and reports the error. Windows versions 3.1 through ME had some level of memory protection, but programs could easily circumvent

3108-750: The Mandarin retroflex consonants . These letters remain in use in Inner Mongolia for the purpose of transcribing Chinese. ཛ When written between words, punctuation marks use space on both sides of them. They can also appear at the very end of a line, regardless of where the preceding word ends. Red (cinnabar) ink is used in many manuscripts, to either symbolize emphasis or respect. Modern punctuation incorporates Western marks: parentheses; quotation, question, and exclamation marks; including precomposed ⁈ and ⁉ . Mongolian numerals are either written from left to right, or from top to bottom. For typographical reasons, they are rotated 90° in modern books to fit on
3182-447: The Mongolian script looks like a vertical Arabic script (in particular the presence of the dot system). Eventually, minor concessions were made to the differences between the Uyghur and Mongol languages: In the 17th and 18th centuries, smoother and more angular versions of the letter tsadi became associated with [ dʒ ] and [ tʃ ] respectively, and in the 19th century,

However, in some systems an application can request that the operating system execute another application within the same process, either as a subroutine or in a separate thread, e.g., the LINK and ATTACH facilities of OS/360 and successors . An interrupt (also known as an abort , exception , fault , signal , or trap ) provides an efficient way for most operating systems to react to
3330-706: The city of Hohhot ; as opposed to other compound words). This also allows components of different harmonic classes to be joined together, and vowels of an added suffix will harmonize with those of the latter part of the compound. Orthographic peculiarities are most often retained, as with the short and long teeth of an initial-shaped ⟨ ᠥ → ᠊ᠥ᠌ ⟩ ö in ᠮᠤᠤ ᠥ᠌ ᠬᠢᠨ Muu' ö kin 'Bad Girl' ( protective name ). Medial t and d , in contrast, are not affected in this way. Isolate citation forms for syllables containing o , u , ö , and ü may in dictionaries appear without
3404-453: The computer's memory. Various methods of memory protection exist, including memory segmentation and paging . All methods require some level of hardware support (such as the 80286 MMU), which does not exist in all computers. In both segmentation and paging, certain protected mode registers specify to the CPU what memory address it should allow a running program to access. Attempts to access other addresses trigger an interrupt, which causes
3478-471: The details of how interrupt service routines behave vary from operating system to operating system. However, several interrupt functions are common. The architecture and operating system must: A software interrupt is a message to a process that an event has occurred. This contrasts with a hardware interrupt — which is a message to the central processing unit (CPU) that an event has occurred. Software interrupts are similar to hardware interrupts — there
3552-422: The environment. Interrupts cause the central processing unit (CPU) to have a control flow change away from the currently running program to an interrupt handler , also known as an interrupt service routine (ISR). An interrupt service routine may cause the central processing unit (CPU) to have a context switch . The details of how a computer processes an interrupt vary from architecture to architecture, and
3626-573: The final phonemes of the syllables, all of which ended in vowels. The script remained in continuous use by Mongolian speakers in Inner Mongolia in the People's Republic of China . In the Mongolian People's Republic , it was largely replaced by the Mongolian Cyrillic alphabet , although the vertical script remained in limited use. In March 2020, the Mongolian government announced plans to increase
3700-410: The hardware checks that the software is only executing legal instructions, whereas the kernel has unrestricted powers and is not subject to these checks. The kernel also manages memory for other processes and controls access to input/output devices. The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with
3774-493: The hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs. Executing an application program typically involves the creation of a process by the operating system kernel , which assigns memory space and other resources, establishes a priority for the process in multi-tasking systems, loads program binary code into memory, and initiates execution of

The first computers in the late 1940s and 1950s were directly programmed either with plugboards or with machine code inputted on media such as punch cards , without programming languages or operating systems. After the introduction of

A multicomputer or cluster computer has multiple CPUs, each of which has its own memory . Multicomputers were developed because large multiprocessors are difficult to engineer and prohibitively expensive; they are universal in cloud computing because of
4070-534: The line. Listed in the table below are letter components ( graphemes ) commonly used across the script. Some of these are used with several letters, and others to contrast between them. As their forms and usage may differ between writing styles , however, examples of these can be found under this section below. As exemplified in this section, the shapes of glyphs may vary widely between different styles of writing and choice of medium with which to produce them. The development of written Mongolian can be divided into
4144-400: The memory allocated to a different one. Around the same time, teleprinters began to be used as terminals so multiple users could access the computer simultaneously. The operating system MULTICS was intended to allow hundreds of users to access a large computer. Despite its limited adoption, it can be considered the precursor to cloud computing . The UNIX operating system originated as
4218-408: The need to use it. A general protection fault would be produced, indicating a segmentation violation had occurred; however, the system would often crash anyway. The use of virtual memory addressing (such as paging or segmentation) means that the kernel can choose what memory each program may use at any given time, allowing the operating system to use the same memory locations for multiple tasks. If

The vowel qualities of visually separated vowels and suffixes must likewise harmonize with those of the preceding word stem. Such suffixes are written with front or neutral vowels when preceded by a word stem containing only neutral vowels. Any of these rules might not apply for foreign words however. A separated final form of vowels

The components of an operating system are designed to ensure that various parts of a computer function cohesively. With the de facto obsoletion of DOS , all user software must interact with the operating system to access hardware. The kernel
4440-420: The operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers . In

Therefore, it would slow down the computer if the CPU had to wait for each I/O to finish. Instead, a computer may implement interrupts for I/O completion, avoiding the need for polling or busy waiting. Some computers require an interrupt for each character or word, costing

Other specialized classes of operating systems (special-purpose operating systems), such as embedded and real-time systems, exist for many applications. Security-focused operating systems also exist. Some operating systems have low system requirements (e.g. light-weight Linux distribution ). Others may have higher system requirements. Some operating systems require installation or may come pre-installed with purchased computers ( OEM -installation), whereas others may run directly from media (i.e. live CD ) or flash memory (i.e. USB stick).

In Unix-like operating systems, signals inform processes of the occurrence of asynchronous events. To communicate asynchronously, interrupts are required. One reason a process needs to asynchronously communicate to another process solves
4958-400: The size of the machine needed. The different CPUs often need to send and receive messages to each other; to ensure good performance, the operating systems for these machines need to minimize this copying of packets . Newer systems are often multiqueue —separating groups of users into separate queues —to reduce the need for packet copying and support more concurrent users. Another technique
