Can you please help me understand the memory usage of SQL Server, from what I see in Task manager, please?

Kindly see attached screenshot of the SQL Server memory usage from Task Manager, and also pagefile settings. (windows 2003 server)

I have not set any pagefile to the server. (No Paging File option is set). But the Server says '4095 MB allocated', even though I have set the option to 'No'. The system has 8GB physical memory. the commit charge is out of a total of 12088MB. That is 3896MB more than the 8GB(8192MB). Because 12088MB is > than 8GB, I am assuming that windows somehow has assigned 4095MB of Virtual space to memory, without a physical pagefile.sys file.

The peak commit charge is less than total Physical Memory. Does that mean, the system is fine?

What are the other readings in this screenshot that is important to understand the health of memory usage in SQL Server.
