What is the difference between static page and dynamic page?

Static page means the page is already exists and it is same for all clients at each time. But dynamic pages do not exist directly and it can be different for different client and different time.

Example:
html body todays date is 24th /body /html -- this is static page, always same
html body<%= new java.util.Date()%> /body /html-- this is dynamic page

Here put <> over html and body tag, due to errors i have to skip it.
