Help in google analytics

[seo_gujarat]

My que is about Google analytics.
Whenever I check Navigation summary for particular URL for eg. domain.com/contact.html
then it shows data of 2 factors such as Previous Pages(Entrances) and Next Pages(Exits).
But, I can't understand of what is the mean of Previous Pages(Entrances) and Next Pages(Exits).

If anybody know about it, please share your idea here.

Thanks in advance.:)

Entrance means they came to your page from another site (this page was the landing page on your site).
Exits means they left your site (by closing the browser, clicking a link, or typing a new URL in the browser).
Previous page means the page they came from on your site to get to your page.
Next page means the page they went to on your site when they left your page.

The pages listed below Previous and Next are the pages they came from and went to on your site.

The navigation summary gives you an idea of how people get to your page and which links they click to leave the page.
