Can someone describe when to use Access vs General mode and the reason(s) why?

I have seen numerous example configurations with both and the "desired" results appears to be the same.

I have a pair of 6248's and a 6224.  I want to configure the pair of 6248's for my workstations and printers(vlan1...3) and servers (vlan4).  The 6224 is for ISCSI (vlan5).  Of course, the 6248's are stacked and the 6224 is not but has a trunked port to the stack.  Routing will be enabled on the stack but not on the 6224.

I have routing figured out so routing between vlans is not the issue.  My issue has been trying various configurations for the ports regarding vlans.  Simply put, I want vlan1...3 to access vlan4 but NOT vlan5.  I want vlan4 to access vlan5 for management purposes only (hence no routing on the 6224).

vlan1...3 - use access or general?

vlan4 - use access or general?

vlan5 - use access or general?

An example is would be much appreciated.
