LAB 3 : INTRODUCTION TO HTML TAG

My First Webpage>

My First Webpage

Welcome to my first web page. I am writing this page using a text editor and plain old html.
By learning html, I'll be able to create web pages like a pro....
which I am of course.

LAB 3 : QUESTIONS WITH ANSWERS

1. Explain about the HTML code above
The HTML code is about the language working on displaying html file on a browser. The html file contains important parts such as head, title and body. Function of HTML tags :-

<html> - Defines an html document.

<head> - Contains any code that is not used to display elements on the webpage.
<title> - Defines the title of the webpage..
<body> - Contains the visible elements of the webpage.
<h1> - defines HTML headings where here the title is alligned to the center.
<p> - This element is used to identify blocks of paragraph text with a statement 'Welcome to my first webpage. I am writing this page using a text editor and plain old html'. The closing tag is optional and is implied by the opening tag of the next HTML element encountered in an HTML document after an opening tag.
<br> - This tag is to insert a single line break and later proceeding with 'which I am of course'.

2. Explain about the two types of HTML Tags?

The two types of HTML Tags are paired tags and unpaired tags. The paired tag is said if the text is placed between a tag and its companion tag. In paired tags, the first tag is referred to as Opening Tag and the second tag is referred to as Closing Tag. An unpaired tag does not have a companion tag or closing tag. Unpaired tags are also known as Singular or Stand-Alone Tags.

3. Give some examples of HTML tags on both types of HTML tags.

* Example of PAIRED TAGS

<html> </html>
<body> </body>
<li> </li>
<title> </title>

* Example of UNPAIRED TAGS

LAB 2 : QUESTIONS WITH ANSWERS

1. Explain about the HTML code above?
The HTML code is about the language working on displaying html file on a browser. The html file contains important parts such as head, title and body. Function of HTML tags :-

<html&gt - Defines an html document.

<head&gt - Contains any code that is not used to display elements on the webpage.
<title&gt - Defines the title of the webpage .
<body&gt - Contains the visible elements of the webpage.

2. Why the use of HTM or HTML Extension?

HTML stands for Hyper Text Markup Language, which is a markup language used for creating web pages. HTML actually uses markup tags for describing web pages and applications.
HTML actually uses markup tags for describing web pages. As file extensions, they are denoted as .htm or .html. If you use HTML files to create your web page, then an .html or .htm will most likely appear at the end of its URL. Here are examples: ‘http://code.google.com/chrome/extensions/samples.html’ and ‘http://edgewisdom.com/Finance1.htm’.
HTM is used only as an alternate extension to .HTML. This happens for some reasons, for example, in some operating systems, like the Disk Operating System and Window 3.X, they do not allow the use of four-letter extensions.
HTM or HTML Extension is very important in creating a webpage :-
3. How to view the HTML Source?
- Firefox – CTRL + U (Meaning press the CTRL key on your keyboard and hold it down. While holding down the CTRL key, press the “u” key.) Alternatively, you can go to the “Firefox” menu and then click on “Web Developer,” and then “Page Source.”
- Internet Explorer – CTRL + U. Or right click and select “View Source.”
- Chrome – CTRL + U. Or you can click on the weird-looking key with three horizontal lines in the upper right hand corner. Then click on “Tools” and select “View Source.”
- Opera – CTRL + U. Or you can right click on the webpage and select "View Page Source.key with three horizontal lines in the upper right hand corner. Then click on “Tools” and select “View Source.”

LAB 1 : INTRODUCTION TO THE WEB TECHNOLOGY

World’s First Website, Created By Tim Berners-Lee In 1991

Sir Berners-Lee

Berners-Lee is the director of the World Wide Web Consortium (W3C), which oversees the continued development of the Web.

The World Wide Web (W3) is a wide-area hypermedia information retrieval initiative aiming to give universal access to a large universe of documents. It aims to allow information sharing within internationally dispersed teams and the dissemination of information by support groups. Originally aimed at the High Energy Physics community, it has spread to other areas and attracted much interest in user suppuort, resource discovery and collaboratie work areas.

Berners-Lee first proposed his idea for a worldwide network of computers sharing information in 1989, while he was working at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland. According CERN’s history of the first website, it was written on a NeXT computer (pictured below), made by the company Steve Jobs founded after his ouster from Apple back in 1985.

FIGURE 1 :CERN

By October of 1990, Tim had written the three fundamental technologies that remain the foundation of today’s web (and which you may have seen appear on parts of your web browser):

HTML: HyperText Markup Language. The markup (formatting) language for the web.

URI: Uniform Resource Identifier. A kind of “address” that is unique and used to identify to each resource on the web. It is also commonly called a URL.

HTTP: Hypertext Transfer Protocol. Allows for the retrieval of linked resources from across the web.

What is World Wide Web?

FIGURE 2 : VIDEO

* It is a network of online content that is formatted in HTML and accessed via HTTP. The term refers to all the interlinked HTML pages that can be accessed over the Internet.

* The internet in contrast is the underlying network connection that allows us to send email and access the World Wide Web.

* The early Web was collection of text-based sites hosted by organizations that were technically gifted enough to set up a Web Server and learn HTML.

* It is all the Web pages, pictures, videos and other online content that can be accessed via a Web browser.

* It has continued ti evolved since the original design and it now includes interactie (social) media and user-generated content that requires little to no technical skills.
