"Pages" and "sites" and Refresh!

The world wide web (aka “www”) consists of web sites that have multiple “files” on them.  These are also called “pages” and are sets of code that can be sent to my computer when I click on a link or enter a web address (aka “URL” which stands for some words you can look up if you are interested).  When the file reaches my computer, it is interpreted to create a layout of the “page”.


If the coding is changed after being sent to me, the version of the “page” on my computer will be out of date.  However, I can “refresh” the page, usually by hitting the refresh icon, somewhere near the top of the display. Clicking on the refresh icon tells my computer to send another request for the “page” and get a new copy of the file.  If the “page” in question is something like the news or a sports score, the coding itself might make a page refresh happen every few minutes.


You can make a web site of your own for free by visiting sites.google.com.  If you do, you might find that whatever you put on your site, you forget about over time.  So, there might be information on your site that is badly out of date or incorrect.  That can happen at any web site.


The idea of a world wide web was invented in 1989 but by now, there are billions, probably trillions of web pages on the web.
