CS 100 - Computer Literacy, Fall 2004

Lab 4

This lab assignment will be doing a simple modification of the assignment from lab 3.

A URL is a Uniform Resource Locator. Let us first break down a URL into more parts. We will discuss 4 parts of a URL. There are more parts to a URL, but this will be enough for us.

The URL from last week lab was given as:

     http://icarus.uic.edu/~netid/filename

     where netid is your net-id
     and   filename is the name of the file

     http://icarus.uic.edu/~netid/filename

   in which

     http is  protocol
     icarus.uic.edu is a machine name
     ~netid is a directory on the machine
     filename is a file in the directory

The protocol tells the web browser how it should use the information given by the URL. HTTP stand for HyperText Transer Protocol which is the name for for web pages are encoded. Another protocol include FTP (File Transfer Protocol). We may encounter a few more, but that is enough for now.

The machine specifies the name of the server that is providing the information. Every machine needs a unique name so there is no confusion.

Lab Assignment 4

• Create a file in the web directory of your icarus account with the name of index.html. This file can contain any text you wish as long as your name is given on the first line of the file.

• Verifry that your file is viewable via a web browser at the URL of:

       http://icarus.uic.edu/~NETID
  
       where NETID is your own Net-ID
