What is HTML
Basics
HyperText Markup Language (HTML) is the language of the internet. To fully understand HTML you should first understand how browsers work, and before we discuss bowsers we are going to start with the internet and the web.
Let's start at the beginning
WWW (World Wide Web) is the collection of computers across the globe that are networked together. This means, that computers have a way to talk to each other and exchange the data on the web. The data could be found in different formats such as text, spreadhseets, images, sound files, web pages, etc. All of the above formats are coded and you need an application to translate the code from its original format to the format that is undurstandable to the end user. For example, you need Word for the text files, MP3 player for the sound files and Photoshop for the graphics (JPEG or GIF). Web pages are coded in the same fashion using HTML code, therefore HTML is nothing else but a set of instructions and rules that are used to create web pages.
Browser
Just like you needed an application to translate the text, graphics or sound files, you are going to need an application to translate HTML code and that is known as the browser.
How does this work
When the web pages are coded using html, they are stored an the designated machine called the web server. The web server has the ability to serve the web pages to the computers on the internet that requested them. So the whole process starts when the cliet, let's say your computer, that's connected to the internet, sends the request to the web server. You could do that, by typing the address of the web page to the browser, but we'l get into that shortly. Therefore, first you need a browser (Microsoft Internet Explorer or Netscape), and then you need an internet address of the web server and the page you are looking for, also known as the URL (Uniform Resource Locator). For example, www.iDragstor.com is a valid url for the home page of iDragstor. When the web server receives the request from your computer or the browser that you use, it will serve the requested page in the html format and your browser will translate the html code to the format that's meaningfull to you, and that is what you actually see on the screen.
Let's see how this works in the real world
HTML code will look something like this: :
< img src="elogo.gif" >
When the browser translates the html code from the above you will get something like this:
iDragstor Lab
You are probably asking yourself by now, what is a iDragstor Lab. All the html excercises in this tutor, or any other HTML code, you may try in our lab. This will make it easier for you, but try to do some of the excercises the traditional way. In the next lesson, you will find the instructions on how to do both methods. Happy coding.
The End of Lesson 1 ..
As you can see, HTML is just a way the browser translates the code to the format that makes sense to the end user. Writing HTML code is easier then you think. In the next lesson you will make your first HTML page. For now, you can take the well diserved break before we go to the next lesson.
