General document vs file vs web pages

Another issue that I'm confused about.

Is it true that each Web Page in a given Web Site is a separate .html document or file?

Each document or image is a file? A folder is another term for directory?

 

Virtually it is. Physically it can be anything as the server can host an application that dynamically generates html pages. For example a single physical file can generate thousands of html pages. So you may see a thousand different URLs but on the server end there is just one file that creates them all.

Folders as they appear in the address bar of your browser again can be anything. Can be physical folders or virtual ones generated on the fly by the server application.

Images can be different. You can have a single resource file for the template, that includes multiple images and then utilized with a CSS stylesheet by altering the coordinates of which section each image should display. Typically is done to reduce the number of connections on a server.
Another case is with a thumbnailer or image generator where a single script may generate additional images on the fly to fit an image in a given set of dimensions reducing server bandwidth. Now for product catalogs or image galleries or individual text pages where you see images as part of the content typically separate physical image files are used.

 

Thanks for the speedy reply. I didn't realize that there is much more to a web page than I ever imagined.

So little time ... so much more to learn!
