Some article titles are descriptive rather than being a name. Descriptive titles should be worded neutrally, so as not to suggest a viewpoint for or against a topic, or to confine the content of the article to views on a particular side of an issue for example, an article titled \”Criticisms of X\” might be better renamed \”Societal views on X\”.

Neutral titles encourage multiple viewpoints and responsible article writing. The internal structure of an article may require additional attention to protect neutrality and to avoid problems like POV forking and undue weight. Although specific article structures are not, as a rule, prohibited, care must be taken to ensure the overall presentation is broadly neutral.

Segregation of text or other content into different regions or subsections, based solely on the apparent POV of the content itself, may result in an unencyclopedic structure, such as a back-and-forth dialogue between proponents and opponents. Try to achieve a more neutral text by folding debates into the narrative, rather than isolating them into sections that ignore or fight against each other. Pay attention to headers, footnotes, or other formatting elements that might unduly favor one point of view or one aspect of the subject, and watch out for structural or stylistic aspects that make it difficult for a reader to fairly and equally assess the credibility of all relevant and related viewpoints.

Neutrality requires that mainspace articles and pages fairly represent all significant viewpoints that have been published by reliable sources , in proportion to the prominence of each viewpoint in the published, reliable sources. Generally, the views of tiny minorities should not be included at all, except perhaps in a \”see also\” to an article about those specific views.

For example, the article on the Earth does not directly mention modern support for the flat Earth concept, the view of a distinct and minuscule minority; to do so would give undue weight to it. Undue weight can be given in several ways, including but not limited to the depth of detail, the quantity of text, prominence of placement, the juxtaposition of statements, and the use of imagery. In articles specifically relating to a minority viewpoint, such views may receive more attention and space.

However, these pages should still appropriately reference the majority viewpoint wherever relevant and must not represent content strictly from the minority view\’s perspective.

Specifically, it should always be clear which parts of the text describe the minority view. In addition, the majority view should be explained sufficiently to let the reader understand how the minority view differs from it, and controversies regarding aspects of the minority view should be clearly identified and explained.

How much detail is required depends on the subject. For instance, articles on historical views such as flat Earth, with few or no modern proponents, may briefly state the modern position and then discuss the history of the idea in great detail, neutrally presenting the history of a now-discredited belief. Other minority views may require a much more extensive description of the majority view to avoid misleading the reader. Wikipedia should not present a dispute as if a view held by a small minority is as significant as the majority view.

Views held by a tiny minority should not be represented except in articles devoted to those views such as the flat Earth.

Giving undue weight to the view of a significant minority or including that of a tiny minority might be misleading as to the shape of the dispute. Wikipedia aims to present competing views in proportion to their representation in reliable sources on the subject.

This rule applies not only to article text but to images, wikilinks, external links, categories, templates, and all other material as well. Keep in mind that, in determining proper weight, we consider a viewpoint\’s prevalence in reliable sources, not its prevalence among Wikipedia editors or the general public.

If you can prove a theory that few or none currently believe, Wikipedia is not the place to present such proof. Once it has been presented and discussed in sources that are reliable , it may be appropriately included.

See \” No original research \” and \” Verifiability \”. An article should not give undue weight to minor aspects of its subject but should strive to treat each aspect with a weight proportional to its treatment in the body of reliable, published material on the subject. For example, a description of isolated events, quotes, criticisms, or news reports related to one subject may be verifiable and impartial, but still disproportionate to their overall significance to the article topic.

This is a concern especially for recent events that may be in the news. When there is a consensus of opinion on scientific matters, providing an opposite view without consideration of \’due weight\’ can lead to \’false balance\’, meaning that viewers might perceive an issue to be more controversial than it actually is.

This does not mean that scientists cannot be questioned or challenged, but that their contributions must be properly scrutinized. Including an opposite view may well be appropriate, but [we] must clearly communicate the degree of credibility that the view carries.

While it is important to account for all significant viewpoints on any topic, Wikipedia policy does not state or imply that every minority view or extraordinary claim needs to be presented along with commonly accepted mainstream scholarship as if they were of equal validity. There are many such beliefs in the world, some popular and some little-known: claims that the Earth is flat , that the Knights Templar possessed the Holy Grail , that the Apollo Moon landings were a hoax , and similar ones.

Conspiracy theories , pseudoscience , speculative history , or plausible but currently unaccepted theories should not be legitimized through comparison to accepted academic scholarship. We do not take a stand on these issues as encyclopedia writers, for or against; we merely omit this information where including it would unduly legitimize it, and otherwise include and describe these ideas in their proper context concerning established scholarship and the beliefs of the wider world.

In principle, all articles should be based on reliable , independent , published sources with a reputation for fact-checking and accuracy. When writing about a topic, basing content on the best respected and most authoritative reliable sources helps to prevent bias, undue weight, and other NPOV disagreements. Try the library for reputable books and journal articles, and look online for the most reliable resources.

If you need help finding high-quality sources, ask other editors on the talk page of the article you are working on, or ask at the reference desk. Neutrality assigns weight to viewpoints in proportion to their prominence. However, when reputable sources both contradict one another and also are relatively equal in prominence, describe both points of view and work for balance. This involves describing the opposing views clearly, drawing on secondary or tertiary sources that describe the disagreement from a disinterested viewpoint.

Wikipedia describes disputes. Wikipedia does not engage in disputes. A neutral characterization of disputes requires presenting viewpoints with a consistently impartial tone; otherwise, articles end up as partisan commentaries even while presenting all relevant points of view.

Let us say that the initial value of x was 1 , then two consecutive evaluations of the variable x yields 10 and respectively. In fact, assignment statements are never referentially transparent. Functional programs exclusively use this type of function and are therefore referentially transparent.

Purely functional data structures are often represented in a different way than their imperative counterparts. Arrays can be replaced by maps or random access lists, which admit purely functional implementation, but have logarithmic access and update times. Purely functional data structures have persistence , a property of keeping previous versions of the data structure unmodified.

In Clojure, persistent data structures are used as functional alternatives to their imperative counterparts. Persistent vectors, for example, use trees for partial updating. Calling the insert method will result in some but not all nodes being created. Functional programming is very different from imperative programming.

Pure functional programming completely prevents side-effects and provides referential transparency. Higher-order functions are rarely used in older imperative programming.

A traditional imperative program might use a loop to traverse and modify a list. The following two examples written in JavaScript achieve the same effect: they multiply all even numbers in an array by 10 and add them all, storing the final sum in the variable \”result\”.

There are tasks for example, maintaining a bank account balance that often seem most naturally implemented with state. The pure functional programming language Haskell implements them using monads , derived from category theory. While existing monads may be easy to apply in a program, given appropriate templates and examples, many students find them difficult to understand conceptually, e.

Functional languages also simulate states by passing around immutable states. This can be done by making a function accept the state as one of its parameters, and return a new state together with the result, leaving the old state unchanged. Impure functional languages usually include a more direct method of managing mutable state.

Clojure , for example, uses managed references that can be updated by applying pure functions to the current state. This kind of approach enables mutability while still promoting the use of pure functions as the preferred way to express computations.

Alternative methods such as Hoare logic and uniqueness have been developed to track side effects in programs. Some modern research languages use effect systems to make the presence of side effects explicit. Functional programming languages are typically less efficient in their use of CPU and memory than imperative languages such as C and Pascal. Flat arrays may be accessed very efficiently with deeply pipelined CPUs, prefetched efficiently through caches with no complex pointer chasing , or handled with SIMD instructions.

It is also not easy to create their equally efficient general-purpose immutable counterparts. For purely functional languages, the worst-case slowdown is logarithmic in the number of memory cells used, because mutable memory can be represented by a purely functional data structure with logarithmic access time such as a balanced tree. For programs that perform intensive numerical computations, functional languages such as OCaml and Clean are only slightly slower than C according to The Computer Language Benchmarks Game.

Immutability of data can in many cases lead to execution efficiency by allowing the compiler to make assumptions that are unsafe in an imperative language, thus increasing opportunities for inline expansion.

Lazy evaluation may also speed up the program, even asymptotically, whereas it may slow it down at most by a constant factor however, it may introduce memory leaks if used improperly.

Launchbury [59] discusses theoretical issues related to memory leaks from lazy evaluation, and O\’Sullivan et al. However, the most general implementations of lazy evaluation making extensive use of dereferenced code and data perform poorly on modern processors with deep pipelines and multi-level caches where a cache miss may cost hundreds of cycles [ citation needed ].

It is possible to use a functional style of programming in languages that are not traditionally considered functional languages. JavaScript , Lua , [82] Python and Go [83] had first class functions from their inception. In PHP , anonymous classes , closures and lambdas are fully supported. Libraries and language extensions for immutable data structures are being developed to aid programming in the functional style.

In Java , anonymous classes can sometimes be used to simulate closures ; [87] however, anonymous classes are not always proper replacements to closures because they have more limited capabilities. In C , anonymous classes are not necessary, because closures and lambdas are fully supported.

Libraries and language extensions for immutable data structures are being developed to aid programming in the functional style in C. Many object-oriented design patterns are expressible in functional programming terms: for example, the strategy pattern simply dictates use of a higher-order function, and the visitor pattern roughly corresponds to a catamorphism , or fold.

Similarly, the idea of immutable data from functional programming is often included in imperative programming languages, [90] for example the tuple in Python, which is an immutable array, and Object. Spreadsheets can be considered a form of pure, zeroth-order , strict-evaluation functional programming system.

Several extensions have been developed for spreadsheet programs to enable higher-order and reusable functions, but so far remain primarily academic in nature. Functional programming is an active area of research in the field of programming language theory. There are several peer-reviewed publication venues focusing on functional programming, including the International Conference on Functional Programming , the Journal of Functional Programming , and the Symposium on Trends in Functional Programming.

Functional programming has seen use in a wide variety of industrial applications. Other functional programming languages that have seen use in industry include Scala , [97] F , [18] [19] Wolfram Language , [7] Lisp , [98] Standard ML , [99] [] and Clojure. Functional \”platforms\” have been popular in finance for risk analytics particularly with the larger investment banks. Indeed, functional programming is heavily influenced by category theory.

Many universities teach or have taught functional programming as part of their undergraduate Computer Science degrees. Outside of computer science, functional programming is being used as a method to teach problem solving, algebra and geometric concepts. From Wikipedia, the free encyclopedia. Programming paradigm. For subroutine-oriented programming, see Procedural programming. Main articles: First-class function and Higher-order function.

Main article: Pure function. Main article: Recursion computer science. Main article: Evaluation strategy. Main article: Type system. When negative numbers are required, they are usually stored in two\’s complement notation.

Other arrangements are possible, but are usually not seen outside of specialized applications or historical contexts. A computer can store any kind of information in memory if it can be represented numerically. Modern computers have billions or even trillions of bytes of memory. The CPU contains a special set of memory cells called registers that can be read and written to much more rapidly than the main memory area. There are typically between two and one hundred registers depending on the type of CPU.

Registers are used for the most frequently needed data items to avoid having to access main memory every time data is needed. As data is constantly being worked on, reducing the need to access main memory which is often slow compared to the ALU and control units greatly increases the computer\’s speed.

ROM is typically used to store the computer\’s initial start-up instructions. In general, the contents of RAM are erased when the power to the computer is turned off, but ROM retains its data indefinitely. In embedded computers , which frequently do not have disk drives, all of the required software may be stored in ROM.

Software stored in ROM is often called firmware , because it is notionally more like hardware than software. Flash memory blurs the distinction between ROM and RAM, as it retains its data when turned off but is also rewritable. It is typically much slower than conventional ROM and RAM however, so its use is restricted to applications where high speed is unnecessary. In more sophisticated computers there may be one or more RAM cache memories , which are slower than registers but faster than main memory.

Generally computers with this sort of cache are designed to move frequently needed data into the cache automatically, often without the need for any intervention on the programmer\’s part. Hard disk drives , floppy disk drives and optical disc drives serve as both input and output devices. A graphics processing unit might contain fifty or more tiny computers that perform the calculations necessary to display 3D graphics.

A era flat screen display contains its own computer circuitry. While a computer may be viewed as running one gigantic program stored in its main memory, in some systems it is necessary to give the appearance of running several programs simultaneously.

This is achieved by multitasking i. By remembering where it was executing prior to the interrupt, the computer can return to that task later. If several programs are running \”at the same time\”. Since modern computers typically execute instructions several orders of magnitude faster than human perception, it may appear that many programs are running at the same time even though only one is ever executing in any given instant.

This method of multitasking is sometimes termed \”time-sharing\” since each program is allocated a \”slice\” of time in turn. Before the era of inexpensive computers, the principal use for multitasking was to allow many people to share the same computer. If a program is waiting for the user to click on the mouse or press a key on the keyboard, then it will not take a \”time slice\” until the event it is waiting for has occurred.

This frees up time for other programs to execute so that many programs may be run simultaneously without unacceptable speed loss. Some computers are designed to distribute their work across several CPUs in a multiprocessing configuration, a technique once employed in only large and powerful machines such as supercomputers , mainframe computers and servers.

Multiprocessor and multi-core multiple CPUs on a single integrated circuit personal and laptop computers are now widely available, and are being increasingly used in lower-end markets as a result. Supercomputers in particular often have highly unique architectures that differ significantly from the basic stored-program architecture and from general-purpose computers.

Such designs tend to be useful for only specialized tasks due to the large scale of program organization required to successfully utilize most of the available resources at once. Supercomputers usually see usage in large-scale simulation , graphics rendering , and cryptography applications, as well as with other so-called \” embarrassingly parallel \” tasks.

Software refers to parts of the computer which do not have a material form, such as programs, data, protocols, etc. Software is that part of a computer system that consists of encoded information or computer instructions, in contrast to the physical hardware from which the system is built. Computer software includes computer programs , libraries and related non-executable data , such as online documentation or digital media.

It is often divided into system software and application software Computer hardware and software require each other and neither can be realistically used on its own. There are thousands of different programming languages—some intended for general purpose, others useful for only highly specialized applications.

The defining feature of modern computers which distinguishes them from all other machines is that they can be programmed. That is to say that some type of instructions the program can be given to the computer, and it will process them. Modern computers based on the von Neumann architecture often have machine code in the form of an imperative programming language.

In practical terms, a computer program may be just a few instructions or extend to many millions of instructions, as do the programs for word processors and web browsers for example. A typical modern computer can execute billions of instructions per second gigaflops and rarely makes a mistake over many years of operation. Large computer programs consisting of several million instructions may take teams of programmers years to write, and due to the complexity of the task almost certainly contain errors.

This section applies to most common RAM machine —based computers. In most cases, computer instructions are simple: add one number to another, move some data from one location to another, send a message to some external device, etc.

These instructions are read from the computer\’s memory and are generally carried out executed in the order they were given. However, there are usually specialized instructions to tell the computer to jump ahead or backwards to some other place in the program and to carry on executing from there. These are called \”jump\” instructions or branches. Furthermore, jump instructions may be made to happen conditionally so that different sequences of instructions may be used depending on the result of some previous calculation or some external event.

Many computers directly support subroutines by providing a type of jump that \”remembers\” the location it jumped from and another instruction to return to the instruction following that jump instruction.

Program execution might be likened to reading a book. While a person will normally read each word and line in sequence, they may at times jump back to an earlier place in the text or skip sections that are not of interest.

Similarly, a computer may sometimes go back and repeat the instructions in some section of the program over and over again until some internal condition is met. This is called the flow of control within the program and it is what allows the computer to perform tasks repeatedly without human intervention. Comparatively, a person using a pocket calculator can perform a basic arithmetic operation such as adding two numbers with just a few button presses.

But to add together all of the numbers from 1 to 1, would take thousands of button presses and a lot of time, with a near certainty of making a mistake.

On the other hand, a computer may be programmed to do this with just a few simple instructions. The following example is written in the MIPS assembly language :.

Once told to run this program, the computer will perform the repetitive addition task without further human intervention. It will almost never make a mistake and a modern PC can complete the task in a fraction of a second. In most computers, individual instructions are stored as machine code with each instruction being given a unique number its operation code or opcode for short.

The command to add two numbers together would have one opcode; the command to multiply them would have a different opcode, and so on. The simplest computers are able to perform any of a handful of different instructions; the more complex computers have several hundred to choose from, each with a unique numerical code.

Since the computer\’s memory is able to store numbers, it can also store the instruction codes. This leads to the important fact that entire programs which are just lists of these instructions can be represented as lists of numbers and can themselves be manipulated inside the computer in the same way as numeric data.

The fundamental concept of storing programs in the computer\’s memory alongside the data they operate on is the crux of the von Neumann, or stored program, architecture. This is called the Harvard architecture after the Harvard Mark I computer. Modern von Neumann computers display some traits of the Harvard architecture in their designs, such as in CPU caches. While it is possible to write computer programs as long lists of numbers machine language and while this technique was used with many early computers, [h] it is extremely tedious and potentially error-prone to do so in practice, especially for complicated programs.

These mnemonics are collectively known as a computer\’s assembly language. Converting programs written in assembly language into something the computer can actually understand machine language is usually done by a computer program called an assembler.

Programming languages provide various ways of specifying programs for computers to run. Unlike natural languages , programming languages are designed to permit no ambiguity and to be concise. They are purely written languages and are often difficult to read aloud. They are generally either translated into machine code by a compiler or an assembler before being run, or translated directly at run time by an interpreter. Sometimes programs are executed by a hybrid method of the two techniques.

Machine languages and the assembly languages that represent them collectively termed low-level programming languages are generally unique to the particular architecture of a computer\’s central processing unit CPU. Although considerably easier than in machine language, writing long programs in assembly language is often difficult and is also error prone. Therefore, most practical programs are written in more abstract high-level programming languages that are able to express the needs of the programmer more conveniently and thereby help reduce programmer error.

High level languages are usually \”compiled\” into machine language or sometimes into assembly language and then into machine language using another computer program called a compiler. It is therefore often possible to use different compilers to translate the same high level language program into the machine language of many different types of computer.

This is part of the means by which software like video games may be made available for different computer architectures such as personal computers and various video game consoles. Program design of small programs is relatively simple and involves the analysis of the problem, collection of inputs, using the programming constructs within languages, devising or using established procedures and algorithms, providing data for output devices and solutions to the problem as applicable. As problems become larger and more complex, features such as subprograms, modules, formal documentation, and new paradigms such as object-oriented programming are encountered.

Large programs involving thousands of line of code and more require formal software methodologies. The task of developing large software systems presents a significant intellectual challenge. Producing software with an acceptably high reliability within a predictable schedule and budget has historically been difficult; the academic and professional discipline of software engineering concentrates specifically on this challenge. Errors in computer programs are called \” bugs \”. They may be benign and not affect the usefulness of the program, or have only subtle effects.

But in some cases, they may cause the program or the entire system to \” hang \”, becoming unresponsive to input such as mouse clicks or keystrokes, to completely fail, or to crash.

Bugs are usually not the fault of the computer. Since computers merely execute the instructions they are given, bugs are nearly always the result of programmer error or an oversight made in the program\’s design.

Computers have been used to coordinate information between multiple locations since the s. The U. In time, the network spread beyond academic and military institutions and became known as the Internet. The emergence of networking involved a redefinition of the nature and boundaries of the computer. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an individual computer.

Initially these facilities were available primarily to people working in high-tech environments, but in the s the spread of applications like e-mail and the World Wide Web , combined with the development of cheap, fast networking technologies like Ethernet and ADSL saw computer networking become almost ubiquitous.

In fact, the number of computers that are networked is growing phenomenally. A very large proportion of personal computers regularly connect to the Internet to communicate and receive information.

A computer does not need to be electronic , nor even have a processor , nor RAM , nor even a hard disk. While popular usage of the word \”computer\” is synonymous with a personal electronic computer, [l] the modern definition of a computer is literally: \” A device that computes , especially a programmable [usually] electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information.

There is active research to make computers out of many promising new types of technology, such as optical computers , DNA computers , neural computers , and quantum computers. Most computers are universal, and are able to calculate any computable function , and are limited only by their memory capacity and operating speed. However different designs of computers can give very different performance for particular problems; for example quantum computers can potentially break some modern encryption algorithms by quantum factoring very quickly.

There are many types of computer architectures :. Of all these abstract machines , a quantum computer holds the most promise for revolutionizing computing. The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church—Turing thesis is a mathematical statement of this versatility: any computer with a minimum capability being Turing-complete is, in principle, capable of performing the same tasks that any other computer can perform.

Therefore, any type of computer netbook , supercomputer , cellular automaton , etc. A computer will solve problems in exactly the way it is programmed to, without regard to efficiency, alternative solutions, possible shortcuts, or possible errors in the code.

Computer programs that learn and adapt are part of the emerging field of artificial intelligence and machine learning. Artificial intelligence based products generally fall into two major categories: rule-based systems and pattern recognition systems. Rule-based systems attempt to represent the rules used by human experts and tend to be expensive to develop. Pattern-based systems use data about a problem to generate conclusions.

Examples of pattern-based systems include voice recognition , font recognition, translation and the emerging field of on-line marketing. As the use of computers has spread throughout society, there are an increasing number of careers involving computers. The need for computers to work well together and to be able to exchange information has spawned the need for many standards organizations, clubs and societies of both a formal and informal nature.
