How does a web page actually work?

Question

When you click on an icon, how does the computer know to change the page, or play the song etc? Are there sensors in the screen or something?

Answer 1

A web page is simply a collection of characters. Your computer receives them and later your web browser interprets them. Your web browser is a program that recognises special characters called "tags" that instruct the computer how to display the other type of characters called data. The software differentiates them because who wrote the web page used the symbols "<" and ">" to enclose the instructions. You can see this if you right click on the web page and then click "view source code". Anyone can write a web page if they just know which tags are possible and what parameters they use. HTML is the name (acronym really) of such a way to write web pages. One of the tags is interpreted as a link to other pages or other files (like music or movies). Your browser (and in that, your computer) keeps track on where your cursor is. If it recognises that you did click on one of those links, it will request the web to send that file to your computer and have it start running. Usually the script that makes the web page also tells the browser how to display that file (which can be another web page or a music or video file). Learning HTML might be fun and very useful!

The computer does not need to have sensors in the screen (although there could be, like those screens where you touch your selections; but still it is not required), it only needs to keep track of where your mouse/cursor is and what is it pointing at. All this is done in the computer's memory and taken care of by the software in your computer.

There are two modes of operation: Client-side (done on your PC) and server-side (done on the server). In both cases, the browser activates the response connected to the icon in the web page definition.
The display screen, when using the mouse, does not participate in sensing the selection. The mouse driver sends a command to the operating system which hands the information to the browser. The command states things like:
- cursor location
- mouse button (left, right, middle)
- single or double click
The web page definition selects a response as a function of these variables.

When a touch-sensitive screen is used, the driver for the screen passes similar information to the operating system and thus to the browser.

Answer 3

A web page works by running what is basically a program written in HTML (HyperText Markup Language). In Internet Explorer, select View then Source and, in most cases, you can see the text program. For clicking on an icon to load another page, the program might look like:



This says display image newpage.gif and fetch newpage.htm if the icon is clicked.

Right click on an icon, button on text link and select Properties. You will then see the full path to the document to be loaded (where appropriate).

Answer 4

Everything involved with a website sits on a server somewhere (either on your own computer, or hosted somewhere else). The web pages themselves are programmed in markup languages (such as HTML). The language speaks to your browser, which acts as a middle man between you and the server where the website resides. So, for instance when you click on a link, the command is sent through the browser to the server, which reads through the HTML to find out what that specific link is supposed to do (i.e. go to google.com) and then sends a message back to the browser which completes the action by doing what the server told it to (so google.com pops up).
