Introduction to Internet ?

The internet is a global network of interconnected computers and devices that allows communication and the exchange of information across vast distances. It is a network of networks, linking millions of computers worldwide, and it has become an integral part of modern life.

The internet has its roots in the 1960s when the United States Department of Defense developed a decentralized network called ARPANET to connect computers at different locations. Over time, this network evolved and expanded, eventually leading to the creation of the internet as we know it today.

At its core, the internet relies on a set of protocols known as the Internet Protocol Suite (TCP/IP). These protocols enable devices to establish connections and exchange data packets across the network. The World Wide Web (WWW) is one of the most popular services provided over the internet, allowing users to access and share information through websites, hyperlinks, and web browsers.

The internet has revolutionized communication, commerce, education, and various other aspects of society. It enables people from different parts of the world to connect and interact instantly, regardless of geographical barriers. It has transformed the way we communicate, access information, conduct business, and entertain ourselves.

The internet offers a wide range of services and resources, including email, instant messaging, social media platforms, online shopping, streaming services, search engines, online banking, and much more. It has become a vast repository of knowledge, with access to information on nearly any topic imaginable.

However, the internet also poses challenges and concerns related to privacy, security, and online safety. It is essential for users to be aware of these risks and take necessary precautions to protect their personal information and ensure a safe online experience.

Overall, the internet has had a profound impact on society, transforming the way we live, work, and interact with each other. Its constant evolution continues to shape our world, with new technologies and innovations emerging regularly to enhance connectivity and accessibility.

What is WWW ?

WWW stands for the World Wide Web, which is an information system that allows users to access and navigate websites and webpages over the internet. It is often used interchangeably with the term “web.”

The World Wide Web was invented by Sir Tim Berners-Lee in 1989 while he was working at CERN, the European Organization for Nuclear Research. Berners-Lee developed the necessary technologies and protocols to create a system that would facilitate the sharing and retrieval of information on a global scale.

The WWW operates based on three key components:

  • Web Browsers: These are software applications that allow users to access and view webpages. Popular web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari. Web browsers interpret and render the HTML (Hypertext Markup Language) code used to create webpages, enabling users to interact with the content.
  • Web Servers: These are computers or systems that store and deliver webpages and other web resources to users upon request. When a user enters a website’s URL (Uniform Resource Locator) into their web browser, the browser sends a request to the appropriate web server, which then retrieves and sends the requested webpage back to the user’s browser.
  • Hyperlinks: Hyperlinks, also known as links, are clickable elements within webpages that connect to other webpages or resources. They allow users to navigate between different webpages and websites by simply clicking on the link. Hyperlinks are a fundamental feature of the web and enable the interconnectedness of information.

The WWW revolutionized the way information is accessed and shared. It made it possible to link documents and resources across different websites, creating a vast network of interconnected information. This interconnectedness, facilitated by hyperlinks, allows users to navigate seamlessly between webpages and websites, following their interests and exploring a wide range of topics.

The World Wide Web is just one of the services provided over the internet. Other internet services, such as email, file transfer (FTP), and real-time communication (VoIP), coexist with the WWW to form the broader ecosystem of online communication and information exchange.

Introduction to HTML

HTML, short for Hypertext Markup Language, is the standard markup language used for creating webpages and defining their structure and content. It is the backbone of the World Wide Web and is supported by all modern web browsers.

HTML utilizes a set of tags and elements to mark up text, images, links, and other types of content within a webpage. These tags provide structure and define the presentation of the content. When a web browser renders an HTML document, it interprets the tags and displays the content accordingly.

Here are some key concepts and elements in HTML:

Tags: HTML tags are used to mark up different elements of a webpage. Tags are enclosed within angle brackets (<>) and are usually paired, consisting of an opening tag and a closing tag. For example, the opening tag <h1> defines a heading, and the closing tag </h1> indicates the end of the heading.

Elements: HTML elements are composed of one or more tags and the content they enclose. For instance, the heading element <h1> includes the opening and closing tags, as well as the text that represents the heading itself.

Attributes: HTML attributes provide additional information about an element. They are included within the opening tag and are written as name-value pairs. For example, the attribute “src” in an image tag specifies the source file or URL of the image to be displayed.

Structure: HTML documents have a hierarchical structure. The <html> element serves as the root element and contains two main sections: the <head> section, which contains metadata and information about the webpage, and the <body> section, which contains the visible content of the webpage.

Text Formatting: HTML offers tags for formatting text, such as headings (<h1> to <h6>), paragraphs (<p>), bold text (<b>), italic text (<i>), and more.

Links: HTML allows the creation of hyperlinks using the <a> tag. By specifying the destination URL within the href attribute, users can click on a link and navigate to another webpage or resource.

HTML is a versatile language and supports multimedia elements, forms, tables, lists, and many other features that enable the creation of dynamic and interactive webpages. It works in conjunction with CSS (Cascading Style Sheets) and JavaScript to enhance the visual presentation and add interactivity to webpages.

Learning HTML provides the foundation for web development, allowing you to create static webpages or serve as a starting point for more advanced web technologies and frameworks.

HTML Tags

HTML tags are used to mark up and define different elements within an HTML document. These tags are enclosed within angle brackets (<>) and consist of an opening tag, content, and a closing tag. Here are some commonly used HTML tags:

  • <html>: Represents the root element of an HTML document.
  • <head>: Contains metadata and other information about the webpage, such as the title, character encoding, and links to CSS stylesheets or JavaScript files.
  • <body>: Encloses the visible content of the webpage, including text, images, links, and other elements.
  • <h1> to <h6>: Defines headings of various levels, with <h1> being the highest and <h6> being the lowest.
  • <p>: Represents a paragraph of text.
  • <a>: Creates a hyperlink to another webpage or resource. The destination URL is specified using the href attribute.
  • <img>: Embeds an image in the webpage. The source file or URL of the image is specified using the src attribute.
  • <ul> and <ol>: Used to create unordered (bulleted) and ordered (numbered) lists, respectively.
  • <li>: Represents an item in a list.
  • <table>: Defines a table structure, with rows represented by <tr> tags and cells within rows represented by <td> or <th> tags.
  • <form>: Creates a form for user input, encompassing various form elements such as text fields, checkboxes, radio buttons, and buttons.
  • <input>: Specifies an input field within a form.
  • <div>: Defines a division or section within the document, often used for grouping and styling purposes.
  • <span>: Used to apply styling or other attributes to a specific section of text within a larger block.
  • <header>, <nav>, <article>, <section>, <footer>: Semantic elements used to structure and provide meaning to different sections of the webpage.

These are just a few examples of HTML tags. There are many more tags available to create and structure web content. It’s important to use appropriate tags and follow HTML standards to ensure proper rendering and accessibility of webpages.
