URL does not stand for "you are lost"
Every image, file, page or program has its own individual location on the Web. To find these items, you need the address called a Uniform Resource Locator or URL (pronounced "you are ell"). Like your home address which lists your state, city, street and zip-code, the URL identifies the computer, directory and file where an item is located and the type of protocol needed to read that item. Because every item has its own unique location on the Web, every URL is also unique. Remember that capitalization, punctuation and spacing must be exact for a URL to work.
