Web page
A web page or webpage is a resource of information that is suitable for the World Wide Web and can be accessed through a web browser. This information is usually in HTML or XHTML format, and may provide navigation to other web pages via hypertext links.
Web pages may be retrieved from a local computer or from a remote web server. The web server may restrict access only to a private network, e.g. a corporate intranet, or it may publish pages on the World Wide Web. Web pages are requested and served from web servers using Hypertext Transfer Protocol (HTTP).
Web pages may consist of files of static text stored within the web server's file system (static web pages), or the web server may construct the (X)HTML for each web page when it is requested by a browser (dynamic web pages). Client-side scripting can make web pages more responsive to user input once in the client browser.

HANTU
Kepercayaan mengenai hantu roh atau semangat
Hantu seringkali digambarkan sebagai bersaiz dan berbentuk manusia (walaupun sesetengah gambaran menyebut hantu haiwan), tetapi biasanya digambarkan sebagai "berkilauan", "berbayang", "lutsinar", "seperti kabus", atau seumpamanya. Hantu tidak mempunyai tubuh kasar seperti manusia, hanya bayangan badan (astral body). Kadang kala ia tidak nampak dilihat tetapi dalam fenomena lain seperti pergerakan objek, lampu terpasang atau tertutup dengan sendiri, bunyi, dll, yang tidak mempunyai penjelasan logik.
Di Barat mereka yang mempercayai hantu kadang-kala menganggap mereka sebagai roh yang tidak aman selepas mati, dan dengan itu berkeliaran di Bumi. Ketidakupayaan mendapat keamanan dijelaskan sebagai ada pekerjaan yang belum selesai, seperti mangsa yang mencari keadilan atau dendam selepas mati. Penjenayah, kadang-kala berlegar untuk mengelak Purgatori atau Neraka. Kadang-kala hantu dikatakan berada di awang-awangan, tempat, menurut nonorthodox doktarin Khatolik, antara Syurga dan Neraka di mana roh bayi yang tidak dibaptise tinggal. Penting bagi mengetahui bahawa walaupun Protestan dan Kristian Evangelikal aliran utama percaya kewujudan hantu secara prinsip (principalities), mereka tidak mempercayai hantu (sebagai semangat orang mati) dan meletakkan hantu ganas, seperti poltergeist, kepada tindakan jembalang, sama seperti Islam. Dalam Khatolok dan Kristian Anglikan (dan Christian Spiritualism), percayakan hantu adalah diterima dan boleh dibincang dengan paderi (clergy).
Dalam kebudayaan Asia (seperti di China), ramai orang mempercayai kepada kelahiran semula (reincarnation). Hantu merupakan roh yang enggan "dikitar semula" kerana mereka mempunyai perkara yang belum selesai, sama seperti di Barat. Exorcist boleh membantu menghalau atau mengitar semula hantu (reincarnated). Dalam tradisi Cina, selain dilahirkan semula, hantu boleh menjadi kekal (immortal) dan menjadi separa dewa (demigod), atau ia boleh pergi ke neraka dan menderita kekal selamanya, atau ia boleh mati sekali lagi dan menjadi "hantu kepada hantu". Orang Cina juga percaya bahawa sesetengah hantu, terutamanya mereka yang mati lemas, membunuh manusia bagi menghalang mereka hak dilahirkan semula. Mangsa "pembunuh" paranormal dikenali sebagai ti4si2gui3 (替死鬼), iaitu bagi Cina sama seperti kambing hitam.
Dalam ugama Hindu, maklumat terperinci mengenai hantu terdapat dalam Garuda Purana, skripture dari Vedic tradisi (Hindu).
Kedua-dua Timur dan Barah berkongsi asas yang sama mengenai hantu. Mereka merayau-rayau sekitar tempat mereka sering pergi semasa hidup atau tempat mereka meninggal. Tempat sedemikian dikenali sebagai "rumah berhantu"; kitaran yang mereka lakukan dikenali sebagai "menghantui". Mereka seringkali mengenakan pakaian yang mana mereka sering pakai semasa hidup.
Samsara Buddhist memasukkan konsep alam hantu lapar. Sentient being dalam alam tersebut dirujuk sebagai Hantu Lapar kerana ikatan mereka kepada dunia ini. Asura juga dirujuk sebagai "hantu bergaduh".

Ghost / hantu
Historical background
The belief in ghosts as souls of the departed is closely related to the ancient concept of animism, which attributed souls to everything in nature, including human beings, animals, plants, rocks, etc. [6] As the nineteenth-century anthropologist James Frazer explained in his classic work, The Golden Bough, souls were seen as the creature within that animated the body:
"If a man lives and moves, it can only be because he has a little man or animal inside, who moves him. The animal inside the animal, the man inside the man, is the soul. And as the activity of an animal or man is explained by the presence of the soul, so the repose of sleep or death is explained by its absence; sleep or trance being the temporary, death being the permanent absence of the soul... "[7]
Although the human soul was sometimes symbolically or literally depicted in ancient cultures as a bird or other animal, it was widely held that the soul was an exact reproduction of the body in every feature, even down to clothing the person wore. This is depicted in artwork from various ancient cultures, including such works as the Egyptian Book of the Dead, which shows deceased people in the afterlife appearing much as they did before death, including the style of dress.
Another widespread belief concerning ghosts is that they were composed of a misty, airy, or subtle material. Anthropologists speculate that this may also stem from early beliefs that ghosts were the person within the person, most noticeable in ancient cultures as a person's breath, which upon exhaling in colder climates appears visibly as a white mist.[6] This belief may have also fostered the metaphorical meaning of "breath" in certain languages, such as the Latin spiritus and the Greek pneuma, which by analogy became extended to mean the soul. In the Bible, God is depicted as animating Adam with a breath.
In many cultures malignant, restless, ghosts are distinguished from the more benign spirits which are the subject of Ancestor worship.[8] Although the evidence for ghosts is largely anecdotal, the belief in ghosts throughout history has remained widespread and persistent.
Arguably the first apparition of a ghost recorded in Western culture was in 1211, during the Albigensian Crusade[9]. Gervase of Tilbury, Marshal of Arles, wrote that the image of Guilhem, a boy recently murdered in the forest, appeared in his cousin's home in Beaucaire, near Avignon, France. This series of "visits" lasted all of the summer. Through his cousin, who spoke for him, the boy allegedly held conversations with anyone who wished, until the local priest requested to speak to the boy directly, leading to an extended disquisition on theology. The boy narrated the trauma of death and the unhappiness of his fellow souls in Purgatory, and reported that God was most pleased with the ongoing Crusade against the Cathar heretics, launched three years earlier. The time of the Albigensian Crusade in southern France was marked by intense and prolonged warfare, this constant bloodshed and dislocation of populations being the context for these reported vists by the murdered boy.
Apparitions of the recently deceased, at the moment of their death, to their friends and relations are very commonly reported.[10] One celebrated example was the strange appearance of Vice-Admiral Sir George Tryon, walking through the drawing room, of his family home in Eaton Square, London, looking straight ahead, without exchanging a word to anyone, in front of several guests at a party being given by his wife on 22 June 1893 whilst he was supposed to be in a ship of the Mediterranean Squadron, manouvering of the coast of Syria. Subsequently it was reported that he had gone down with his ship, the HMS Victoria, that very same night, after it had collided with the HMS Camperdown following an unexplained and bizarre order to turn the ship in the direction of the other vessel.[11] Such crisis apparitions have received serious study by parapsychologists with various explanations given to account for them, including telepathy, as well as the traditional view that they represent disembodied spirits.[12][13]
In many traditional accounts, ghosts were thought to be deceased people looking for vengeance, or imprisoned on earth for bad things they did during life. The appearance of a ghost has often been regarded as an omen or portent of death. Seeing one's own ghostly double or "fetch" is a related omen of death.[14]
Most cultures have ghost stories in their mythologies. Many stories from the Middle Ages and the Romantic era rely on the macabre and the fantastic, and ghosts are a major theme in literature from those eras. Ghost stories date back to ancient times, and can be found in many different cultures. The Chinese philosopher, Mo Tzu (470-391 BC), is quoted as having said:
"The way to find out whether anything exists or not is to depend on the testimony of the ears and eyes of the multitude. If some have heard it or some have seen it then we have to say it exists. If no one has heard it and no one has seen it then we have to say it does not exist. So, then, why not go to some village or some district and inquire? If from antiquity to the present, and since the beginning of man, there are men who have seen the bodies of ghosts and spirits and heard their voices, how can we say that they do not exist? If none have heard them and none have seen them, then how can we say they do? But those who deny the existence of the spirits say: "Many in the world have heard and seen something of ghosts and spirits. Since they vary in testimony, who are to be accepted as really having heard and seen them?" Mo Tzu said: As we are to rely on what many have jointly seen and what many have jointly heard, the case of Tu Po is to be accepted."[15] (note: King Hsuan (827-783 BC) executed his minister, Tu Po, on false charges even after being warned that Tu Po's ghost would seek revenge. Three years later, according to historical chronicles, Tu Po's ghost shot and killed Hsuan with a bow and arrow before an assembly of feudal lords.)
One of the earliest known ghost "sightings" in the west took place in Athens, Greece.[16] Pliny the Younger (c. (50 AD) described it in a letter to Licinius Sura: Athenodoros Cananites (c. 74 BC – 7 AD), a Stoic philosopher, decided to rent a large, Athenian house, to investigate widespread rumors that it was haunted. Athenodoros staked out at the house that night, and, sure enough, a disheveled, aged spectre, bound at feet and hands with rattling chains, eventually "appeared". The spirit then beckoned for Athenodoros to follow him; Athenodoros complied, but the ghost soon vanished. The philosopher marked the spot where the old man had disappeared, and, on the next day, advised the magistrates to dig there. The man's shackled bones were reportedly uncovered three years later. After a proper burial, the hauntings ceased.[17]
Many Eastern religious traditions also subscribe to the concept of ghosts. The Hindu Garuda Purana has detailed information about ghosts.[18]
The Hebrew Torah and the Bible contain few references to ghosts, associating spiritism with forbidden occult activities cf. Deuteronomy 18:11. The most notable reference is in the First Book of Samuel (I Samuel 28:7-19 KJV), in which a disguised King Saul has the Witch of Endor summon the spirit of Samuel. In the New Testament, Jesus has to persuade the Disciples that he is not a ghost following the resurrection, Matthew 24. In a similar vein, Jesus' followers at first believe him to be a ghost when they see him walking on water.
The Child ballad Sweet William's Ghost recounts the story of a ghost returning to beg a woman to free him from his promise to marry her, as he obviously cannot being dead; her refusal would mean his damnation. This reflects a popular British belief that the dead would haunt their lovers if they took up with a new love without some formal release.[19]
The Unquiet Grave expresses a belief even more widespread, found in various location over Europe: ghosts can stem from the excessive grief of the living, whose mourning interferes with the dead's peaceful rest.[20]
In many folktales from around the world, the hero arranges for the burial of a dead man. Soon after, he gains a companion who aids him and, in the end, the hero's companion reveals that he is in fact the dead man.[21] Instances of this include the Italian fairy tale Fair Brow and the Swedish The Bird 'Grip'.

Software systems
There is a wide range of software systems, such as Java Server Pages (JSP), the PHP and Perl programming languages, Active Server Pages (ASP) and ColdFusion (CFM) that are available to generate dynamic Web systems and dynamic sites. Sites may also include content that is retrieved from one or more databases or by using XML-based technologies such as RSS.
Static content may also be dynamically generated either periodically, or if certain conditions for regeneration occur (cached) in order to avoid the performance loss of initiating the dynamic engine on a per-user or per-connection basis.
Plugins are available to expand the features and abilities of Web browsers, which use them to show active content, such as Flash, Shockwave or applets written in Java. Dynamic HTML also provides for user interactivity and realtime element updating within Web pages (i.e., pages don't have to be loaded or reloaded to effect any changes), mainly using the DOM and JavaScript, support which is built-in to most modern Web browsers.
Turning a website into an income source is a common practice for web-developers and website owners. There are several methods for creating a website business which fall into two broad categories, as defined below.
1. Content based sites
Some websites derive revenue by selling advertising space on the site (see contextual ads).
2. Product or service based sites
Some websites derive revenue by offering products or services. In the case of e-commerce websites, the products or services may be purchased at the website itself, by entering credit card or other payment information into a payment form on the site. While most business websites serve as a shop window for existing brick and mortar businesses, it is increasingly the case that some websites are businesses in their own right; that is, the products they offer are only available for purchase on the web.
Websites occasionally derive income from a combination of these two practices. For example, a website such as an online auctions website may charge the users of its auction service to list an auction, but also display third-party advertisements on the site, from which it derives further income.
Dynamic website
A Dynamic Website is one that does not have web pages stored on the server in the same form as the user will view them. Instead, the web page content changes automatically and/or frequently based on certain criteria. It generally collates information on the hop each time a page is requested.
There are two meanings for a dynamic website. The first is that the web page code is constructed dynamically, piece by piece. The second is that the web page content displayed varies based on certain criteria. The criteria may be pre-defined rules or may be based on variable user input.
A dynamic website is also called a Web Application, a Data-driven website or an oCRAFT website because it presents variable information that is tailored to a particular user. It may accept a user’s input and respond to the request. For example, a user can enter text into a login form or keyword search, which prompts the website to fulfill the request and return a unique result. In addition, the user may be able to perform tasks that may alter the website itself, such as post a comment or update a user profile. Examples of task-based websites include, online banking, shopping, e-learning, and social networking. Furthermore, the website may be able to make instant decisions on the fly in various situations, such as online quiz scoring or credit card processing.
This type of website usually displays different information depending on the visitor, thus the information is dynamic. Similar to talking to a customer service representative on the telephone, a dynamic website will provide personalized, real-time information and take the appropriate action intended to serve the customer’s needs immediately. The website usually requires advanced programming and a database, and it often includes admin tools for the website owner to update the website content frequently and easily.
In summary, visitors are able to control what information they wish to receive via a dynamic website, instead of settling for only static content that the website owner has decided to offer. In addition, a visitor may be able to manipulate the content of the website and perform a multitude of tasks.
The term oCRAFT website stands for Online Customer Request and Fulfillment Tools. A website that accepts user input is said to have a customer request tool, such as a form. A website that generates dynamic results, makes decisions or enables a user to perform tasks is said to have a customer fulfillment tool, such as logins, searches, update/edit/post user data, banking, shopping, e-learning and social networking.
Many commonly known modules are oCRAFT tools, such as Forums, Blogs, Wikis, photo galleries, calendars and more. Others include: data banks, directories, listings, profiles, surveys, questionnaires, quizzes/tests, registration/entry forms, order/quote requests, financial calculators, graphs/charts, event management, order tracking, inventory control, product catalog, checkout, e-commerce, auctions, classifieds, social networking, match-making, job boards, portfolio, logins, subscriptions, memberships, affiliate programs, e-learning, course registration/scheduling, delivery/service/appointment scheduling, task tracking, support ticket system, reservations, approval process/work flows, member services, account/profile management, investment account management, lead capture/response/routing, chat, email and much more.
oCRAFT can also be used internally and for company intranets, with tools such as employee/shift scheduling, project management, forecasting/analysis, client relationship management (CRM), content management system (CMS), sales force automation, work order and service request system, workforce training and more.
The main purpose behind a dynamic site is that it is much simpler to maintain a few web pages plus a database than it is to build and update hundreds or thousands of individual web pages and links. In one way, a data-driven website is similar to a static site because the information that is presented on the site is still limited to what the website owner has allowed to be stored in the database. The advantage is that there is usually a lot more information stored in a database and made available to users.
A dynamic website would call various bits of information from a database and put them together in a pre-defined format to present the reader with a coherent page. It interacts with users in a variety of ways including by reading cookies recognizing users' previous history, session variables, server side variables etc., or by using direct interaction (form elements, mouseovers, etc.). A site can display the current state of a dialogue between users, monitor a changing situation, or provide information in some way personalized to the requirements of the individual user.
Some countries, for example the U.K. have introduced legislation regarding web accessibility [1].
Website styles
Static Website
A Static Website is one that has web pages stored on the server in the same form as the user will view them. It is primarily coded in HTML (Hyper-text Markup Language).
A static website is also called a Classic website, a 5-page website or a Brochure website because it simply presents pre-defined information to the user. It may include information about a company and its products and services via text, photos, Flash animation, audio/video and interactive menus and navigation.
This type of website usually displays the same information to all visitors, thus the information is static. Similar to handing out a printed brochure to customers or clients, a static website will generally provide consistent, standard information for an extended period of time. Although the website owner may make updates periodically, it is a manual process to edit the text, photos and other content and may require basic website design skills and software.
In summary, visitors are not able to control what information they receive via a static website, and must instead settle for whatever content the website owner has decided to offer at that time.
They are edited using four broad categories of software:
- Text editors. such as Notepad or TextEdit, where the HTML is manipulated directly within the editor program
- WYSIWYG offline editors. such as Microsoft FrontPage and Adobe Dreamweaver (previously Macromedia Dreamweaver), where the site is edited using a GUI interface and the underlying HTML is generated automatically by the editor software
- WYSIWYG Online editors, where the any media rich online presentation like websites, widgets, intro, blogs etc. are created on a flash based platform.
- Template-based editors, such as Rapidweaver and iWeb, which allow users to quickly create and upload websites to a web server without having to know anything about HTML, as they just pick a suitable template from a palette and add pictures and text to it in a DTP-like fashion without ever having to see any HTML code.
