I am having a hard time answering the question of what is the difference between a logical design of a network and a physical design of a network. Physical Design. The logical design is generally performed in four steps, which are as follows. In this way, we can furnish an abstraction of the total system throughlogical design in an orderly explanatory way.CONCLUSION:So, we can come to a conclusion from the above explanation that logical design of a system isactually an abstraction of the data flows, inputs and outputs whereas, physical design is actuallyrelated to the actual input and output processes of the system, total absence of abstraction here. The physical aspects of our information resources are well understood by developers; e.g., computer hardware/software, DBMS files, manual files, screens, reports, forms, etc. Whereas logical information resources will remain relatively static, the physical resources will change dynamically." Key Differences Between Physical and Logical Topology Physical topology is basically the physical layout of the network media.
