Website is a collection of related web pages, including multimedia content, usually identified with common domain names, and published on at least one web server. Noteworthy examples are wikipedia.org, google.com, and amazon.com.
Websites may be accessed through public Internet Protocol (IP) networks, such as the Internet, or private local area networks (LANs), referring to the uniform resource locator (URL) that identifies the site.
The website can have many functions and can be used in various modes; websites may be personal websites, corporate websites for companies, government websites, organizational websites, etc. Websites are usually dedicated to a particular topic or destination, from entertainment and social networking to providing news and education. All publicly accessible websites are collectively the World Wide Web, while personal websites, such as corporate websites for employees, are usually part of an intranet.
Web pages, which are the building blocks of websites, are documents, usually arranged in plain text interspersed with Hypertext Markup Language formatting instructions (HTML, XHTML). They can combine elements from other websites with the appropriate markup markup. Web pages accessed and transported with Hypertext Transfer Protocol (HTTP), which can optionally use encryption (HTTP Secure, HTTPS) to provide security and privacy for users. User applications, often web browsers, render page content according to HTML markup instructions to the display terminal.
Hyperlinking between web pages conveys to readers the structure of the site and guides site navigation, which often begins with a home page containing the website's content directory. Some websites require user registration or subscription to access the content. Examples of subscription websites include many business sites, news websites, academic journal websites, gaming websites, file sharing websites, message boards, web-based email, social networking websites, websites that provide real-time stock market data , as well as sites that provide various other services. By 2018, end users can access websites on a variety of devices, including desktop and laptop computers, tablet computers, smartphones and smart TVs.

Histori
The World Wide Web (WWW) was created in 1990 by the British CERN physicist Tim Berners-Lee. On April 30, 1993, CERN announced that the World Wide Web would be free to use for anyone. Before the introduction of HTML and HTTP, other protocols such as File Transfer Protocol and gopher protocols were used to retrieve individual files from the server. This protocol offers a simple directory structure where users navigate and select files to download. Documents are most often presented as plain text files without formatting, or encoded in a word-processing format.

Overview
The website has many functions and can be used in various modes; the website may be a personal website, commercial website, government website, or a nonprofit website. Websites may be the work of individuals, businesses, or other organizations, and are usually dedicated to a particular topic or purpose. Any website can contain hyperlinks to other websites, so the differences between individual sites, as perceived by users, can be blurred. Websites are written in, or converted to, HTML (Hyper Text Markup Language) and accessed using software interfaces classified as user agents. Web pages can be viewed or accessed from various computer-based and Internet-equipped devices of any size, including desktop computers, laptops, tablet computers, and smartphones. A website is hosted on a computer system known as a web server, also called an HTTP (Hyper Text Transfer Protocol) server. These terms may also refer to software running on this system which retrieves and sends web pages in response to requests from website users. Apache is the most used web server software (according to Netcraft statistics) and Microsoft's IIS is also commonly used. Some alternatives, such as Nginx, Lighttpd, Hiawatha or Cherokee, are fully functional and lightweight.
Static website
Static websites are websites that have web pages stored on servers in a format sent to the client's web browser. It's mainly encoded in Hypertext Markup Language (HTML); Cascading Style Sheets (CSS) are used to control views outside of regular HTML. Images are typically used to influence the desired look and as part of the main content. Audio or video can also be considered "static" content if it is played automatically or generally not interactive. This type of website typically displays the same information for all visitors. Similar to distributing printed brochures to customers or clients, static websites will generally provide consistent standard information for long periods of time. Although website owners can periodically update, it is a manual process for editing text, photos, and other content and may require basic website design skills and software. Simple forms or examples of website marketing, such as the classic website , the website five pages or the brochure website are often static websites, as they present pre-defined static information to the user. This may include information about the company and its products and services through text, photos, animations, audio/video, and navigation menus.
Static websites can be edited using four broad software categories:
- Text editors, such as Notepad or TextEdit, where HTML content and markup are manipulated directly in the program editor
- WYSIWYG offline editors, such as Microsoft FrontPage and Adobe Dreamweaver (formerly Macromedia Dreamweaver), with which sites are edited using GUI and final HTML markup generated automatically by the editor software
- WYSIWYG online editor that makes media-rich online presentations such as web pages, widgets, intros, blogs, and other documents.
- Template-based editors such as iWeb allow users to create and upload web pages to web servers without detailed HTML knowledge, as they select the appropriate template from the palette and add images and text into desktop publishing mode without directly manipulating the HTML code.
Static websites may still use server-side include (SSI) as convenience edits, such as sharing common menu bars on multiple pages. Since the for reader behavior of the site is still static, it is not considered a dynamic site.
Dynamic website
Dynamic websites are sites that often change or customize themselves and automatically. The server-side dynamic page is generated "on the fly" by the computer code that generates HTML (CSS is responsible for appearance and thus, is a static file). There are various software systems, such as CGI, Java Servlets and Java Server Pages (JSP), Active Server Pages and ColdFusion (CFML) available to generate dynamic web systems and dynamic sites. Various web application frameworks and web template systems are available for commonly used programming languages ​​such as Perl, PHP, Python and Ruby to make it faster and easier to create complex dynamic websites.
Sites may display the current state of the dialogue among users, monitor changed situations, or provide information in a personalized way to suit individual user needs. For example, when a news site's home page is requested, code running on a web server may incorporate stored HTML fragments with news taken from another database or website via RSS to generate pages that include up-to-date information. Dynamic sites can be interactive by using HTML forms, storing and re-reading browser cookies, or by creating a series of pages that reflect the history of previous hits. Another example of dynamic content is when a retail website with a media product database lets users enter a search query, e.g. for the Beatles keyword. In response, the contents of the web page will spontaneously change the way you see it before, and will then display a list of Beatles products like CDs, DVDs and books. Dynamic HTML uses JavaScript code to instruct the web browser how to change the page content interactively. One way to simulate certain types of dynamic websites while avoiding loss of performance from starting dynamic machines on a per-user basis or per connection, is to periodically automatically regenerate a large set of static pages.
Rich media and interactive content
The initial website has only text, and soon after, the image. The plugin in the web browser is then used to add audio, video, and interactivity (such as for rich Internet applications that reflect the complexity of desktop applications such as word processors). Examples of such plug-ins are Microsoft Silverlight, Adobe Flash, Adobe Shockwave, and applets written in Java. HTML 5 includes provisions for audio and video without plugins. JavaScript is also built in most modern web browsers, and allows website creators to send code to web browsers instructing them how to modify the page content interactively and communicate with the web server if needed. The internal representation of the content browser is known as the Document Object Model (DOM) and this technique is known as Dynamic HTML. 2010 era trends on websites called "responsive design" have provided the best viewing experience as they provide device-based layouts for users. This website changes its layout according to the device or mobile platform thereby providing a rich user experience.
Spelling
While "website" is the original spelling (sometimes the uppercase "Web site", since "Web" is the correct noun when referring to the World Wide Web), this variant has become rarely used, and "website" has become standard spelling. All major style guides, such as The Chicago Manual of Style and AP Stylebook , have reflected this change.
Type
Websites can be divided into two broad categories - static and interactive. Interactive sites are part of the Web 2.0 community, and allow interactivity between site owners and site visitors or users. Static sites serve or capture information but do not allow direct engagement with audiences or users. Some websites are informative or produced by fans or for personal or entertainment use. Many websites aim to make money, using one or more business models, including:
- Post interesting content and sell contextual ads either through direct sales or through an advertising network.
- E-commerce: products or services purchased directly through the website
- The ad product or service is available in the brick and mortar business
- Freemium: basic content is available for free but premium content requires payment (eg, WordPress website, this is an open source platform for creating blogs or websites.)
There are many types of websites, each of which specializes in a particular type of content or use, and they can be arbitrarily classified in various ways. Some such classifications may include:
Some websites may belong to one or more of these categories. For example, a business website may promote a business product, but may also host informative documents, such as white paper. There are also many subcategories for the ones listed above. For example, a porn site is a type of e-commerce site or a specific business site (that is, it tries to sell membership for access to its site) or has social networking capabilities. A fanite can be the dedication of the owner to a particular celebrity. Websites are limited by architectural constraints (for example, dedicated computing power for a website). Extremely large websites, such as Facebook, Yahoo !, Microsoft, and Google use multiple servers and load balancers like Cisco Content Services Switches to distribute visitor loads over multiple computers in multiple locations. As of early 2011, Facebook uses 9 data centers with around 63,000 servers.
In February 2009, Netcraft, an Internet monitoring company that has tracked Web growth since 1995, reported that there were 215,675,903 websites with domain names and content in them in 2009, compared to only 19,732 websites in August 1995. After reaching 1 billion web sites in September. 2014, a milestone confirmed by NetCraft in the October 2014 Web Server Survey and that Internet Live Stats was first announced - as evidenced by this tweet from World Wide Web's own inventor Tim Berners-Lee - the number of websites in the world subsequently declined, returning to a level below 1 billion. This is due to the monthly fluctuations in the count of inactive websites. The number of websites continues to grow to more than 1 billion in March 2016, and has grown ever since.
