Available Bytes displays the size of the virtual memory currently on the Zeroed, Free, and Standby lists.  Zeroed and Free memory is ready for use, with Zeroed memory cleared to zeros.  Standby memory is memory removed from a process's Working Set but still available.  Notice that this is an instantaneous count, not an average over the time interval.
