Answer 2

When you put in a URL (paste, type, click on a link or Favorite), the text is sent to a server at your internet provider, which uses the text to query a list, perhaps on another server, of all the URL's in the world, which returns a 4 part number. That number contains the routing to the machine with the information. The part you typed is sent to that machine, which looks at the next part to come up with the location on that machine (folders, etc.) and the exact file name desired. After fhe file name may be additional options. Some of these options are handled at the source machine (like those ending in an item number.) Something is sent back over the internet.
When that something arrives back on your computer, the browser does something with it. Taking the simplest option, an HTML file, the received material is plain text which contains instructions to be carried out within the browser on your machine. These include the text you see, information about the display of the text like font, color, size, and information about arrangements on the screen - like tables. Also, links in the document are highlighted. Along the way, it encounters paths or partial paths to images and sounds and sends requests for those over the internet. If the page is set up with reserved areas for the pictures, the browser will display the first and fill in the spaces as the pictures arrive. If sizes are not specified for the pictures, it waits until all the pictures arrive, looks at the sizes, figures out how they will fit on the screen, fits the text around them and finally displays the text and pictures (sometimes the text is thrown up and then rearranged as the pictures arrive, so if you are reading the text, it jumps around.)
