Do you know why some Web pages end in htm, others end in html, others end in asp and so on? Why all the different extensions?
You can see some of the most common extensions on these URLs:
When the Web started, it ran almost exclusively on UNIX machines and all pages were Html which was the standard file extension. When people started using PCs running DOS or Windows as Web servers, however, the four letters in "html" were problematic. PCs followed an 8.3 naming convention that allowed only three letters in the extension. So the world made room for two standard extensions: html and htm
Htm and Html pages are static. The file is lifted off the server's disk and sent verbatim to the client.
