Web hosting service
A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity in a data center. Web hosts can provide data center space and connectivity to the Internet for other servers located in their data center, called colocation known as Housing in Latin America or France; until 1991, the Internet was restricted to use only...for research and education in the sciences and engineering... and was used for email, telnet, FTP and USENET traffic - but only a tiny number of web pages. The World Wide Web protocols had only just been written and not until the end of 1993 would there be a graphical web browser for Mac or Windows computers. After there was some opening up of internet access, the situation was confused until 1995. To host a website on the internet, an individual or company would need their own server.
As not all companies had the budget or expertise to do this, web hosting services began to offer to host users' websites on their own servers, without the client needing to own the necessary infrastructure required to operate the website. The owners of the websites called webmasters, would be able to create a website that would be hosted on the web hosting service's server and published to the web by the web hosting service; as the number of users on the World Wide Web grew, the pressure for companies, both large and small, to have an online presence grew. By 1995, companies such as GeoCities and Tripod were offering free hosting; the most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol or a Web interface. The files are delivered to the Web "as is" or with minimal processing. Many Internet service providers offer this service free to subscribers. Individuals and organizations may obtain Web page hosting from alternative service providers.
Free web hosting service is offered by different companies with limited services, sometimes supported by advertisements, limited when compared to paid hosting. Single page hosting is sufficient for personal web pages. Personal web site hosting is free, advertisement-sponsored, or inexpensive. Business web site hosting has a higher expense depending upon the size and type of the site. Many large companies that are not Internet service providers need to be permanently connected to the web to send email, etc. to other sites. The company may use the computer as a website host to provide details of their goods and services and facilities for online orders. A complex site calls for a more comprehensive package that provides database support and application development platforms; these facilities allow customers to write or install scripts for applications like forums and content management. Secure Sockets Layer is used for websites that wish to keep the data transmitted more secure. Internet hosting services can run Web servers.
The scope of web hosting services varies greatly. One's website is placed on the same server as many other sites, ranging from a few sites to hundreds of websites. All domains may share a common pool of server resources, such as RAM and the CPU; the features available with this type of service can be quite basic and not flexible in terms of software and updates. Resellers sell shared web hosting and web companies have reseller accounts to provide hosting for clients. Allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a reseller. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a colocated server. Many resellers provide a nearly identical service to their provider's shared hosting plan and provide the technical support themselves. Known as a Virtual Private Server, divides server resources into virtual servers, where resources can be allocated in a way that does not directly reflect the underlying hardware.
VPS will be allocated resources based on a one server to many VPSs relationship, however virtualisation may be done for a number of reasons, including the ability to move a VPS container between servers. The users may have root access to their own virtual space. Customers are sometimes responsible for patching and maintaining the server or the VPS provider may provide server admin tasks for the customer; the user gains full control over it. One type of dedicated hosting is unmanaged; this is the least expensive for dedicated plans. The user has full administrative access to the server, which means the client is responsible for the security and maintenance of his own dedicated server; the user is not allowed full control over it. The user is disallowed full control so that the provider can guarantee quality of service by not allowing the user to modify the server or create configuration problems; the user does not own the server. The server is leased to the client. Similar to the dedicated web hosting service.
Microsoft Corporation is an American multinational technology company with headquarters in Redmond, Washington. It develops, licenses and sells computer software, consumer electronics, personal computers, related services, its best known software products are the Microsoft Windows line of operating systems, the Microsoft Office suite, the Internet Explorer and Edge web browsers. Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface lineup of touchscreen personal computers; as of 2016, it is the world's largest software maker by revenue, one of the world's most valuable companies. The word "Microsoft" is a portmanteau of "microcomputer" and "software". Microsoft is ranked No. 30 in the 2018 Fortune 500 rankings of the largest United States corporations by total revenue. Microsoft was founded by Bill Gates and Paul Allen on April 4, 1975, to develop and sell BASIC interpreters for the Altair 8800, it rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Microsoft Windows.
The company's 1986 initial public offering, subsequent rise in its share price, created three billionaires and an estimated 12,000 millionaires among Microsoft employees. Since the 1990s, it has diversified from the operating system market and has made a number of corporate acquisitions, their largest being the acquisition of LinkedIn for $26.2 billion in December 2016, followed by their acquisition of Skype Technologies for $8.5 billion in May 2011. As of 2015, Microsoft is market-dominant in the IBM PC-compatible operating system market and the office software suite market, although it has lost the majority of the overall operating system market to Android; the company produces a wide range of other consumer and enterprise software for desktops and servers, including Internet search, the digital services market, mixed reality, cloud computing and software development. Steve Ballmer replaced Gates as CEO in 2000, envisioned a "devices and services" strategy; this began with the acquisition of Danger Inc. in 2008, entering the personal computer production market for the first time in June 2012 with the launch of the Microsoft Surface line of tablet computers.
Since Satya Nadella took over as CEO in 2014, the company has scaled back on hardware and has instead focused on cloud computing, a move that helped the company's shares reach its highest value since December 1999. In 2018, Microsoft surpassed Apple as the most valuable publicly traded company in the world after being dethroned by the tech giant in 2010. Childhood friends Bill Gates and Paul Allen sought to make a business utilizing their shared skills in computer programming. In 1972 they founded their first company, named Traf-O-Data, which sold a rudimentary computer to track and analyze automobile traffic data. While Gates enrolled at Harvard, Allen pursued a degree in computer science at Washington State University, though he dropped out of school to work at Honeywell; the January 1975 issue of Popular Electronics featured Micro Instrumentation and Telemetry Systems's Altair 8800 microcomputer, which inspired Allen to suggest that they could program a BASIC interpreter for the device. After a call from Gates claiming to have a working interpreter, MITS requested a demonstration.
Since they didn't yet have one, Allen worked on a simulator for the Altair while Gates developed the interpreter. Although they developed the interpreter on a simulator and not the actual device, it worked flawlessly when they demonstrated the interpreter to MITS in Albuquerque, New Mexico. MITS agreed to distribute it, marketing it as Altair BASIC. Gates and Allen established Microsoft on April 4, 1975, with Gates as the CEO; the original name of "Micro-Soft" was suggested by Allen. In August 1977 the company formed an agreement with ASCII Magazine in Japan, resulting in its first international office, "ASCII Microsoft". Microsoft moved to a new home in Bellevue, Washington in January 1979. Microsoft entered the operating system business in 1980 with its own version of Unix, called Xenix. However, it was MS-DOS. After negotiations with Digital Research failed, IBM awarded a contract to Microsoft in November 1980 to provide a version of the CP/M OS, set to be used in the upcoming IBM Personal Computer.
For this deal, Microsoft purchased a CP/M clone called 86-DOS from Seattle Computer Products, which it branded as MS-DOS, though IBM rebranded it to PC DOS. Following the release of the IBM PC in August 1981, Microsoft retained ownership of MS-DOS. Since IBM had copyrighted the IBM PC BIOS, other companies had to reverse engineer it in order for non-IBM hardware to run as IBM PC compatibles, but no such restriction applied to the operating systems. Due to various factors, such as MS-DOS's available software selection, Microsoft became the leading PC operating systems vendor; the company expanded into new markets with the release of the Microsoft Mouse in 1983, as well as with a publishing division named Microsoft Press. Paul Allen resigned from Microsoft in 1983 after developing Hodgkin's disease. Allen claimed that Gates wanted to dilute his share in the company when he was diagnosed with Hodgkin's disease because he didn't think he was working hard enough. After leaving Microsoft, Allen lost billions of dollars on ill-conceived or mistimed technology investments.
He invested in low-tech sectors, sports teams, commercial real estate. Despite having begun jointly developing a new operating system, OS/2, with IBM in
Entertainment is a form of activity that holds the attention and interest of an audience, or gives pleasure and delight. It can be an idea or a task, but is more to be one of the activities or events that have developed over thousands of years for the purpose of keeping an audience's attention. Although people's attention is held by different things, because individuals have different preferences in entertainment, most forms are recognisable and familiar. Storytelling, drama and different kinds of performance exist in all cultures, were supported in royal courts, developed into sophisticated forms and over time became available to all citizens; the process has been accelerated in modern times by an entertainment industry that records and sells entertainment products. Entertainment evolves and can be adapted to suit any scale, ranging from an individual who chooses a private entertainment from a now enormous array of pre-recorded products; the experience of being entertained has come to be associated with amusement, so that one common understanding of the idea is fun and laughter, although many entertainments have a serious purpose.
This may be the case in the various forms of ceremony, religious festival, or satire for example. Hence, there is the possibility that what appears as entertainment may be a means of achieving insight or intellectual growth. An important aspect of entertainment is the audience, which turns a private recreation or leisure activity into entertainment; the audience may have a passive role, as in the case of persons watching a play, television show, or film. Entertainment can be public or private, involving formal, scripted performance, as in the case of theatre or concerts. Most forms of entertainment have persisted over many centuries, evolving due to changes in culture and fashion for example with stage magic. Films and video games, for example, although they use newer media, continue to tell stories, present drama, play music. Festivals devoted to music, film, or dance allow audiences to be entertained over a number of consecutive days; some activities that were once considered entertaining public punishments, have been removed from the public arena.
Others, such as fencing or archery, once necessary skills for some, have become serious sports and professions for the participants, at the same time developing into entertainment with wider appeal for bigger audiences. In the same way, other necessary skills, such as cooking, have developed into performances among professionals, staged as global competitions and broadcast for entertainment. What is entertainment for one group or individual may be regarded as work by another; the familiar forms of entertainment have the capacity to cross over different media and have demonstrated a unlimited potential for creative remix. This has ensured the continuity and longevity of many themes and structures. Entertainment can be distinguished from other activities such as education and marketing though they have learned how to use the appeal of entertainment to achieve their different goals. Sometimes entertainment can be a mixture for both; the importance and impact of entertainment is recognised by scholars and its increasing sophistication has influenced practices in other fields such as museology.
Psychologists say the function of media entertainment is "the attainment of gratification". No other results or measurable benefit are expected from it; this is in contrast to marketing. However, the distinctions become blurred when education seeks to be more "entertaining" and entertainment or marketing seek to be more "educational"; such mixtures are known by the neologisms "edutainment" or "infotainment". The psychology of entertainment as well as of learning has been applied to all these fields; some education-entertainment is a serious attempt to combine the best features of the two. Some people are entertained by the idea of their unhappiness. An entertainment might produce some insight in its audience. Entertainment may skillfully consider universal philosophical questions such as: "What is the meaning of life?". Questions such as these drive many narratives and dramas, whether they are presented in the form of a story, play, book, comic, or game. Dramatic examples include Shakespeare's influential play Hamlet, whose hero articulates these concerns in poetry.
Novels give great scope for investigating these themes. An example of a creative work that considers philosophical questions so entertainingly that it has been presented in a wide range of forms is The Hitchhiker's Guide to the Galaxy. A radio comedy, this story became so popular that it has appeared as a novel, television series, stage show, audiobook, LP record, adventure game and online game, its ideas became popular references and has been tran
A computing platform or digital platform is the environment in which a piece of software is executed. It may be the hardware or the operating system a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed with it. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage. A platform can be seen both as a constraint on the software development process, in that different platforms provide different functionality and restrictions. For example, an OS may be a platform that abstracts the underlying differences in hardware and provides a generic command for saving files or accessing the network. Platforms may include: Hardware alone, in the case of small embedded systems. Embedded systems can access hardware directly, without an OS. A browser in the case of web-based software; the browser itself runs on a hardware+OS platform, but this is not relevant to software running within the browser.
An application, such as a spreadsheet or word processor, which hosts software written in an application-specific scripting language, such as an Excel macro. This can be extended to writing fully-fledged applications with the Microsoft Office suite as a platform. Software frameworks. Cloud computing and Platform as a Service. Extending the idea of a software framework, these allow application developers to build software out of components that are hosted not by the developer, but by the provider, with internet communication linking them together; the social networking sites Twitter and Facebook are considered development platforms. A virtual machine such as the Java virtual machine or. NET CLR. Applications are compiled into a format similar to machine code, known as bytecode, executed by the VM. A virtualized version of a complete system, including virtualized hardware, OS, storage; these allow, for instance, a typical Windows program to run on. Some architectures have multiple layers, with each layer acting as a platform to the one above it.
In general, a component only has to be adapted to the layer beneath it. For instance, a Java program has to be written to use the Java virtual machine and associated libraries as a platform but does not have to be adapted to run for the Windows, Linux or Macintosh OS platforms. However, the JVM, the layer beneath the application, does have to be built separately for each OS.

Adaptive bitrate streaming
Adaptive bitrate streaming is a technique used in streaming multimedia over computer networks. While in the past most video or audio streaming technologies utilized streaming protocols such as RTP with RTSP, today's adaptive streaming technologies are exclusively based on HTTP and designed to work efficiently over large distributed HTTP networks such as the Internet, it works by detecting a user's bandwidth and CPU capacity in real time and adjusting the quality of the media stream accordingly. It requires the use of an encoder; the player client switches between streaming the different encodings depending on available resources. "The result: little buffering, fast start time and a good experience for both high-end and low-end connections."More and as the implementations in use today are, adaptive bitrate streaming is a method of video streaming over HTTP where the source content is encoded at multiple bit rates each of the different bit rate streams are segmented into small multi-second parts.
The streaming client is made aware of the available streams at differing bit rates, segments of the streams by a manifest file. When starting, the client requests the segments from the lowest bit rate stream. If the client finds the download speed is greater than the bit rate of the segment downloaded it will request the next higher bit rate segments. If the client finds the download speed for a segment is lower than the bit rate for the segment, therefore the network throughput has deteriorated it will request a lower bit rate segment; the segment size can vary depending on the particular implementation, but they are between two and ten seconds. Post-production houses, content delivery networks and studios use adaptive bit rate technology in order to provide consumers with higher quality video using less manpower and fewer resources; the creation of multiple video outputs for adaptive bit rate streaming, adds great value to consumers. If the technology is working properly, the end user or consumer's content should play back without interruption and go unnoticed.
Media companies have been using adaptive bit rate technology for many years now and it has become standard practice for high-end streaming providers. Traditional server-driven adaptive bitrate streaming provides consumers of streaming media with the best-possible experience, since the media server automatically adapts to any changes in each user's network and playback conditions; the media and entertainment industry benefit from adaptive bitrate streaming. As the video space grows, content delivery networks and video providers can provide customers with a superior viewing experience. Adaptive bitrate technology requires additional encoding, but simplifies the overall workflow and creates better results. HTTP-based adaptive bitrate streaming technologies yield additional benefits over traditional server-driven adaptive bitrate streaming. First, since the streaming technology is built on top of HTTP, contrary to RTP-based adaptive streaming, the packets have no difficulties traversing firewall and NAT devices.
Second, since HTTP streaming is purely client-driven, all adaptation logic resides at the client. This reduces the requirement of persistent connections between client application. Furthermore, the server is not required to maintain session state information on each client, increasing scalability. Existing HTTP delivery infrastructure, such as HTTP caches and servers can be seamlessly adopted. A scalable CDN is used to deliver media streaming to an Internet audience; the CDN receives the stream from the source at its Origin server replicates it to many or all of its Edge cache servers. The end-user is redirected to the "closest" Edge server; this can be tested using libdash and the Distributed DASH dataset, which has several mirrors across Europe and the US. The use of HTTP-based adaptive streaming allows the Edge server to run a simple HTTP server software, whose licence cost is cheap or free, reducing software licensing cost, compared to costly media server licences; the CDN cost for HTTP streaming media is similar to HTTP web caching CDN cost.
Adaptive bit rate over HTTP was created by the DVD Forum at the WG1 Special Streaming group in October 2002. The group was co-chaired by Toshiba and Phoenix Technologies, The expert group count with the collaboration of Microsoft, Apple Computer, DTS Inc. Warner Brothers, 20th Century Fox, Digital Deluxe, Disney and Akamai; the technology was called DVDoverIP and was an integral effort of the DVD ENAV book. The concept came from storing MPEG-1 and MPEG-2 DVD TS Sectors into small 2KB files, which will be served using an HTTP server to the player; the MPEG-1 segments provided the lower bandwidth stream, while the MPEG-2 provided a higher bit rate stream. The original XML schema provided a simple playlist of bit rates and url servers; the first working prototype was presented to the DVD Forum by Phoenix Technologies at the Harman Kardon Lab in Villingen Germany. Adaptive bit rate streaming was introduced by Move Networks and is now being developed and utilized by Adobe Systems, Apple and Octoshape.
In October 2010, Move Networks was awarded a patent for their adaptive bit rate streaming. MPEG-DASH is the only adaptive bit-rate HTTP-based streaming solution, an international standard MPEG-DASH technology was developed under MPEG. Work on DASH started in 2010.
A home server is a computing server located in a private residence providing services to other devices inside or outside the household through a home network or the Internet. Such services may include file and printer serving, media center serving, web serving, web caching, file sharing and synchronization and contact sharing and synchronization, account authentication and backup services; because of the low number of computers on a typical home network, a home server does not require significant computing power. Home servers can be implemented do-it-yourself style with a re-purposed, older computer, or a plug computer. An uninterruptible power supply is sometimes used in case of power outages that can corrupt data. Home servers run headless, can be administered remotely through a command shell, or graphically through a remote desktop system such as RDP, VNC, Apple Remote Desktop, or many others; some home server operating systems include a consumer-focused graphical user interface for setup and configuration, available on home computers on the home network.
Others enable users to use native operating system tools for configuration. Home servers act as network-attached storage providing the major benefit that all users' files can be centrally and securely stored, with flexible permissions applied to them; such files can be accessed from any other system on the network, provided the correct credentials are supplied. This applies to shared printers; such files can be shared over the Internet to be accessible from anywhere in the world using remote access. Servers running Unix or Linux with the free Samba suite can provide domain control, custom logon scripts, roaming profiles to users of certain versions of Windows; this allows a user to log on from any machine in the domain and have access to her or his "My Documents" and personalized Windows and application preferences - multiple accounts on each computer in the home are not needed. Home servers are used to serve multi-media content, including photos and video to other devices in the household. Using standard protocols such as DLNA or proprietary systems such as iTunes, users can access their media stored on the home server from any room in the house.
Windows XP Media Center Edition, Windows Vista, Windows 7 can act as a home server, supporting a particular type of media serving that streams the interactive user experience to Media Center Extenders including the Xbox 360. Windows Home Server supports media streaming to Xbox 360 and other DLNA-based media receivers via the built-in Windows Media Connect technology; some Windows Home Server device manufacturers, such as HP, extend this functionality with a full DLNA implementation such as PacketVideo TwonkyMedia server. There are many open-source and functional programs for media serving available for Linux. LinuxMCE is one example, which allows other devices to boot off a hard drive image on the server, allowing them to become appliances such as set-top boxes. Asterisk, MythTV, VideoLAN, SlimServer, DLNA, many other open-source projects are integrated for a seamless home theater/automation/telephony experience. On an Apple Macintosh server, options include iTunes, PS3 Media Server, Elgato.
Additionally, for Macs directly connected to TVs, Boxee can act as a full-featured media center interface. Servers are always on so the addition of a TV or radio tuner allows recording to be scheduled at any time; some home servers provide remote access to media and entertainment content. A home server can be used to provide remote access into the home from devices on the Internet, using remote desktop software and other remote administration software. For example, Windows Home Server provides remote access to files stored on the home server via a web interface as well as remote access to Remote Desktop sessions on PCs in the house. Tonido provides direct access via a web browser from the Internet without requiring any port forwarding or other setup; some enthusiasts use VPN technologies as well. On a Linux server, two popular tools are Webmin. VNC allows clients to remotely view a server GUI desktop as if the user was physically sitting in front of the server. A GUI need not be running on the server console for this to occur.
Webmin allows users to control many aspects of server configuration and maintenance all from a simple web interface. Both can be configured to be accessed from anywhere on the Internet. Servers can be accessed remotely using the command line-based Telnet and SSH protocols; some users choose to run a web server in order to share files and publicly. Others set up web pages and serve them straight from their home, although this may be in violation of some ISPs terms of service. Sometimes these web servers are run on a nonstandard port in order to avoid the ISP's port blocking. Example web servers used on home servers include Apache and IIS. Many other web servers are available; some networks have an HTTP proxy which can be used to speed up web access when multiple users visit the same websites, to get past blocking software while the owner is using the network of some institution that might block certain sites. Public proxies are slow and unreliabl
News is information about current events. This may be provided through many different media: word of mouth, postal systems, electronic communication, or through the testimony of observers and witnesses to events. Common topics for news reports include war, politics, health, the environment, business and entertainment, as well as athletic events, quirky or unusual events. Government proclamations, concerning royal ceremonies, taxes, public health, criminals, have been dubbed news since ancient times. Humans exhibit a nearly universal desire to learn and share news, which they satisfy by talking to each other and sharing information. Technological and social developments driven by government communication and espionage networks, have increased the speed with which news can spread, as well as influenced its content; the genre of news as we know it today is associated with the newspaper, which originated in China as a court bulletin and spread, with paper and printing press, to Europe. The English word "news" developed in the 14th century as a special use of the plural form of "new".
In Middle English, the equivalent word was newes, like the German Neues. Similar developments are found in the Slavic languages the Czech and Slovak noviny, the cognate Polish nowiny, the Bulgarian novini, Russian novosti – and in the Celtic languages: the Welsh newyddion and the Cornish nowodhow. Jessica Garretson Finch is credited with coining the phrase "current events" while teaching at Barnard College in the 1890s; as its name implies, "news" connotes the presentation of new information. The newness of news gives it an uncertain quality which distinguishes it from the more careful investigations of history or other scholarly disciplines. Whereas historians tend to view events as causally related manifestations of underlying processes, news stories tend to describe events in isolation, to exclude discussion of the relationships between them. News conspicuously describes the world in the present or immediate past when the most important aspects of a news story have occurred long in the past—or are expected to occur in the future.
To make the news, an ongoing process must have some "peg", an event in time which anchors it to the present moment. Relatedly, news addresses aspects of reality which seem unusual, deviant, or out of the ordinary. Hence the famous dictum that "Dog Bites Man" is not news. Another corollary of the newness of news is that, as new technology enables new media to disseminate news more quickly,'slower' forms of communication may move away from'news' towards'analysis'. According to some theories, "news" is. Journalism, broadly understood along the same lines, is the act or occupation of collecting and providing news. From a commercial perspective, news is one input, along with paper necessary to prepare a final product for distribution. A news agency supplies this resource "wholesale" and publishers enhance it for retail. Most purveyors of news value impartiality and objectivity, despite the inherent difficulty of reporting without political bias. Perception of these values has changed over time as sensationalized'tabloid journalism' has risen in popularity.
Michael Schudson has argued that before the era of World War I and the concomitant rise of propaganda, journalists were not aware of the concept of bias in reporting, let alone correcting for it. News is sometimes said to portray the truth, but this relationship is elusive and qualified. Paradoxically, another property attributed to news is sensationalism, the disproportionate focus on, exaggeration of, emotive stories for public consumption; this news is not unrelated to gossip, the human practice of sharing information about other humans of mutual interest. A common sensational topic is violence. Newsworthiness is defined as a subject having sufficient relevance to the public or a special audience to warrant press attention or coverage. Journalists apply news values to identify a news story. News values determine how much attention a news story is given by a media outlet, the attention it is given by its audience or readers. In some countries and at some points in history, what news media and the public have considered "newsworthy" has met different definitions, such as the notion of news values.
Many news values seem to be common across cultures. People seem to be interested in news to the extent which it has a big impact, describes conflicts, happens nearby, involves well-known people, deviates from the norms of everyday happenings. War is a common news topic because it involves unknown events that could pose personal danger. Evidence suggests that cultures around the world have found a place for people to share stories about interesting new information. Among Zulus, Mongolians and American Southerners, anthropologists have documented the practice of questioning travelers for news as a matter of priority. Sufficiently important news would be repeated and and could spread by word of mouth over a large geographic area; as printing presses came into use in Europe, news for the general public travelled orally via monks, town criers, etc. The news is transmitted in public gathering places, such as the Greek forum and the Roman baths. Starting in England, coffeehouses served as important sites for the spread of news after telecommunications became available.
The history of the coffee houses is traced from Arab countries, introduced in England in 16th century. In th
