Logical data independence is considered more difficult than physical data independence because it involves changes to the conceptual schema and external schema, which are more closely tied to the way data is organized and viewed in the application. Physical data independence, on the other hand, deals with changes to the internal schema, which is more abstract and can be modified with less impact on the overall system.

PACKET INTERNET GROPER uses ICMP echo request and reply messages to check the physical and logical connectivity of machines on an internetwork . Hence Ping works on layer 3 of OSI model.
difference between physical and logical data flow diagrams.
It is generally considered more difficult to achieve logical data independence compared to physical data independence. Logical data independence involves separating the conceptual structure of the data from the physical storage aspects, which can be complex depending on the database design. Physical data independence primarily deals with shielding the application from changes in the storage structure, which is usually more straightforward to achieve.

Yes, a physical topology can support multiple logical topologies.
* Physical file (PF) contains the data and have only one record format. Logical file (LF) is a view of the physical file which does not contain any data may be based on one physical file or more then one physical file. Logical file can have more then one record format. Logical can be non join or join logical file. Performance becomes better if you use the logical file in the program.
token ring uses a physical star and a logical ring ,while FDDI uses a physical star/ring and a logical ring.
