Create a Simple Web

                    Create  a  Simple   Web



Web Page

A web page (or webpage) is a hypertext document on the World Wide Web. Web Pages are delivered by a Web server to the user  and displayed in a Web browser . A Web site consists of many web pages  linked together  under a common domain name . The  name "Web Page" is a metaphor of  paper pages  bound together into a book

 A web page can contain huge information including text, graphics, audio, video and hyper links. These hyper links are the link to other web pages

Collection of linked  web pages on a web server is  known as website. There is unique Uniform Resource Locator (URL)  is associated with each web page.

Web Browser

A Web Browser (also referred to as av Internet browser or a simply a browser) is  application software for  accessing  the World Wide Web  or a local website.

 When  a user requests a web page from a particular  website, the web browser retrieves the necessary content from a web sever and then displays the page on the user's device.

Web browser can show  text, audio, video, animation  and more.

A web browser is a not the same thing as a search  engine, though the two are often confused. A search engine  is web site that provide links to other websites. However, to connect pages, a user must have a web browser installed.

Web browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones.
                         Ex :- Mozilla Firefox
                                  Google Chrome
                                  Microsoft  Internet Explorer
                                  Apple Safari
                                 Opera Browser

In 2021, an estimated  4.9  billion people used a browser. The most used browser is Google Chrome, with a 65.67% global market share on all devices , followed by Safari with 20% .

Web Server

Web  Server  is a computer software and underlying  hardware that accepts  requests via HTTP(the network protocol created to distribute web content) or its secure variant HTTPS.

A user agent, commonly a web browser or web crawler, initiates communication by making a request for a web page or other resource using HTTP, and the server responds with the content of that resource or an error message. 

A web server can also accept  and store resources  sent from the user agent  if configured to do so. 

Website is  collection of web pages while web server is a software that  respond to the request for web resources.

Search  Engine

Search Engine is a software system  designed  to  carry out web searches.

Search Engine refers to a huge database of internet resources such as web pages, newsgroups, programs, images etc.

It helps to locate information on World Wide Web.

User can search for any information  by passing query in form of  keywords or phrase.

It then searches for relevant information in its database and  return to the user.

What does  HTTP  mean.....?

Hypertext Transfer Protocol ( HTTP) Secure is an extension of the Hypertext Transfer Protocol.

It is used for secure communication over a computer network, and is widely used on the Internet. 

In HTTPS, the communication protocol is encrypted using Transport Layer Security or, formerly, Secure Sockets Layer.

World  Wide  Web  Communication

The  World Wide Web  is about communication  between  web clients and  web server.

Clients  are  often browsers ( Chrome, Edge, Safari), but they can be any type of  program or device.

Severs are most often computers in the cloud.  


Communication   between  clients  and server is done by requests and responses. 
  • A client(a browser) sends  an HTTP  request  to the web .
  • A web server receives the  request.
  •  The server runs an application  to process  the request.
  • The server returns an HTTP  response (output)  to the browser.
  • The client (the browser) receives the response.

What  is HTML.....?

The Hyper Text Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.

Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.

HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. HTML elements are delineated by tags, written using angle brackets. Tags such as <img /> and <input /> directly introduce content into the page. Other tags such as <p> surround and provide information about document text and may include other tags as sub-elements. Browsers do not display the HTML tags but use them to interpret the content of the page.

HTML can embed programs written in a scripting language such as JavaScript, which affects the behavior and content of web pages. Inclusion of CSS defines the look and layout of content. The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997.[2] A form of HTML, known as HTML5, is used to display video and audio, primarily using the <canvas> element, in collaboration with java script.

HTML  Editors

An HTML editor is a software for editing and creating HTML code that is used for websites or other web documents. With text-based HTML editors, the source code can be edited directly. WYSIWYG editors show the document to be edited already the way it displayed in the browser later.
  • Some of  the popular  HTML  text editors  are  given below.      
                            Notepad++     

                            
VS Code
                           Sublime Text
