Cache System:
When a page is rendered, php and mysql are used. Therefore, system needs RAM and CPU. If many visitors come to a site, system uses lots of RAM and CPU so page is rendered so slowly. In this case, you need a cache system not to render page again and again. Cache system generates a static html file and saves. Other users reach to static html page.
Browser Caching:

when i browser caching enabled and there are new comments how long does that to you to see?
Browser caching is not enable for html. nevertheless browser caching cause an issue that the user cannot see the changes.
there is a solution for the problem?
and have the normal cache the same problem?
if I cache enabled I am not logged-in in wordpress frontend!
You need to enable the following option.
Logged-in Users: [X] Don’t show the cached version for logged-in users
OK THX but i have the problem i have a comment edit and the canche not visible for other users!
Post change are visible immediately but not comments
only when I update the post or delete cache change is visible in comments!
but new comments works
Now I got it.
When a comment is approved, the cache of page is deleted.
ok but when i edit a approved comment, the change dont visible! the edit of a commen dont delete cache!
and browser cache have the same problems?
ok but when i edit a approved comment, the change dont visible! the edit of a commen dont delete cache!
now I got it. I will investigate and let you know.

The problem is not about browser caching.
what I have noticed
if cache is activated on the blog the time when an article was published (Time Ago) is not work until the cache cleared!
Show Post 1 Minute ago until the cache cleared!
If it is done with php, it does not work surely. It must be done with Javascript.
