A website is a collection of related web pages served from a single web domain. Websites can be created by individuals, businesses, and organizations to share information on a specific topic or purpose. Websites are made up of web pages written in HTML and CSS that are accessed via URLs using the HTTP protocol. Websites can be static, with fixed pages of content, or dynamic, with automatically changing or personalized content generated from databases or scripts.

2. About website
•A website, also written as web site, or simply site, is a set of related web
pages typically served from a single web domain. A website is hosted on at least
one web server, accessible via a network such as the Internet or a private local area
network through an Internet address known as a uniform resource locator (URL). All
publicly accessible websites collectively constitute the World Wide Web.
•Web pages, which are the building blocks of websites, are documents, typically
written in plain text interspersed with formatting instructions of Hypertext Mark up
Language (HTML, XHTML). They may incorporate elements from other websites with
suitable mark up anchors. Webpages are accessed and transported with
the Hypertext Transfer Protocol (HTTP), which may optionally employ encryption
(HTTP Secure, HTTPS) to provide security and privacy for the user of the webpage
content. The user's application, often a web browser, renders the page content
according to its HTML mark up instructions onto a display terminal.

3. CONTINUE
• The pages of a website can usually be accessed from a simple Uniform Resource Locator (URL)
called the web address. The URLs of the pages organize them into a hierarchy,
although hyperlinking between them conveys the reader's perceived site structure and guides the
reader's navigation of the site which generally includes a home page with most of the links to the
site's web content, and a supplementary about, contact and link page.
• Some websites require a subscription to access some or all of their content. Examples
of subscription websites include many business sites, parts of news websites, academic
journal websites, gaming websites, file-sharing websites, message boards, web-
based email, social networking websites, websites providing real-time stock market data, and
websites providing various other services.

4. History of websites
•The World Wide Web (WWW) was created in 1990 by the British CERN
physicist Tim Berners-Lee. On 30 April 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 the gopher protocol were used to retrieve
individual files from a server. These protocols offer a simple directory
structure which the user navigates and chooses files to download.
•Documents were most often presented as plain text files without
formatting, or were encoded in word processor formats.

5. Overview on websites
•Websites have many functions and can be used in various fashions; a
website can be a personal website, a commercial website, a government
website or a non-profit organization website.
•Websites can be the work of an individual, a business or other
organization, and are typically dedicated to a particular topic or purpose.
Any website can contain a hyperlink to any other website, so the distinction
between individual sites, as perceived by the user, can be blurred.
•Websites are written in, or converted to, HTML (Hyper Text Mark up
Language) and are accessed using a software interface classified as a user
agent.
•Web pages can be viewed or otherwise accessed from a range
of computer-based and Internet-enabled devices of various sizes, including
desktop computers, laptops, PDAs and cell phones.

6. Static website•A static website is one that has web pages stored on the
server in the format that is sent to a client web browser. It is
primarily coded in Hypertext Mark up
Language (HTML); Cascading Style Sheets (CSS) are used to
control appearance beyond basic HTML. Images are
commonly used to effect the desired appearance and as part
of the main content. Audio or video might also be considered
"static" content if it plays automatically or is generally non-
interactive.
•This type of website usually displays the same information to
all visitors. 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

7. Dynamic
website
•A dynamic website is one that changes or customizes itself frequently and automatically.
•Server-side dynamic pages are generated "on the fly" by computer code that produces the
HTML (CSS are responsible for appearance and thus, are static files). There are a wide range of
software systems, such as CGI, Java Servlets and Java Server Pages (JSP), Active Server
Pages and ColdFusion (CFML) that are available to generate dynamic web systems and dynamic
sites. Various web application frameworks and web template systems are available for general-
use programming languages like PHP, Perl, Python, and Ruby, to make it faster and easier to
create complex dynamic web sites.
•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. For
example, when the front page of a news site is requested, the code running on the web server
might combine stored HTML fragments with news stores retrieved from a database or another
web site via RSS to produce a page that includes the latest information. Dynamic sites can be
interactive by using HTML forms, storing and reading back browser cookies, or by creating a
series of pages that reflect the previous history of clicks. Another example of dynamic content is
when a retail website with a database of media products allows a user to input a search request,
e.g. for the keyword Beatles. In response, the content of the web page will spontaneously change
the way it looked 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 interactively modify the
page contents.
•One way to simulate a certain type of dynamic web site while avoiding the performance loss of

8. Multimedia and interactive content
•Early web sites had only text, and soon after, images. Web browser plugins were
then used to add audio, video, and interactivity 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 into most modern web browsers, and allows for web site
creators to send code to the web browser that instructs it how to interactively modify
page content and communicate with the web server if needed. (The browser's
internal representation of the content is known as the Document Object
Model (DOM) and the technique is known as Dynamic HTML.
•A more recent trend in websites called "responsive design" has given the best of
viewing experience as it provides with a device based layout for users. These
websites change their layout according to the device or mobile platform thus giving a
rich user experience.

9. Types of website
•Websites can be divided into two broad categories - static and interactive.
Interactive sites are part of the Web 2.0 community of sites, and allow for
interactivity between the site owner and site visitors. Static sites serve or capture
information but do not allow engagement with the audience directly.
•Some web sites are informational or produced by enthusiasts or for personal
use or entertainment. Many web sites do aim to make money, using one or more
business models, including:
1. Posting interesting content and selling contextual advertising either through
direct sales or through an advertising network.
2. E-commerce - products or services are purchased directly through the web
site.
3. Advertising products or services available at a brick and mortar business.
4. Freemium - basic content is available for free but premium content is paid.

10. continue
•Some websites may be included in one or more of these categories. For example, a business website
may promote the business's products, but may also host informative documents, such as white papers.
There are also numerous sub-categories to the ones listed above.
•Websites are constrained by architectural limits. Very large websites, such as Facebook, Yahoo!,
Microsoft, and Google employ many servers and load balancing equipment such as Cisco Content
Services Switches to distribute visitor loads over multiple computers at multiple locations. As of early
2011, Facebook utilized 9 data centres with approximately 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 on them in 2009,
compared to just 19,732 websites in August 1995.
•After reaching 1 billion websites in September 2014, a milestone confirmed by Net Craft in its October
2014 Web Server Survey and that Internet Live Stats was the first to announce - as attested by this tweet
from the inventor of the World Wide Web himself, Tim Berners-Lee - the number of websites in the world
has subsequently declined, reverting to a level below 1 billion. This is due to the monthly fluctuations in
the count of inactive websites.
