The logical design of a network refers to the design of how information will flow through a network, etc.  The physical desgin relates to the actual physical pieces (servers, workstations, routers, etc) and their locations in the network.  This site gives a pretty good description of both methods.

In many networks, the logical and physical designs can look very similar.  But the support for VLANs on switches allows them to differ, and sometimes they do -- radiacally.

A physical layout is going to be in terms of devices, and cables connecting them.  A logical layout is going to be in terms of subnets and gateways connecting (or separating...) them.
