- Hyperlinks (Strings of text that are links to other pages)
When a user clicks on a hyperlink, the browser carries out a
series of steps in order to fetch the page pointed to. Suppose that a user is
browsing the Web and finds a link on Internet telephony that points to ITU's
home page, which is http://www.itu.org/home/index.html. Let us trace the
steps that occur when this link is selected.
-
The browser determines the URL (by seeing what was
selected).
-
The browser asks DNS for the IP address of www.itu.org.
-
DNS replies with 156.106.192.32.
-
The browser makes a TCP connection to port 80 on
156.106.192.32.
-
It then sends over a request asking for file /home/index.html.
-
The www.itu.org server sends the
file /home/index.html.
-
The TCP connection is released.
-
The browser displays all the text in /home/index.html.
-
The browser fetches and displays all images in this file
