different types of caching using cache object of ASP.NET?

What are different types of caching using cache object ofASP.NET?
You can use two types of output caching to cache information that is to be transmitted to and
displayed in a Web browser:
• Page Output Caching
Page output caching adds the response of page to cache object. Later when
page is requested page is displayed from cache rather than creating the
page object and displaying it. Page output caching is good if the site is
fairly static.
• Page Fragment Caching
If parts of the page are changing, you can wrap the static sections as user
controls and cache the user controls using page fragment caching.
