What is physical data structure and logical data structure?
Physical data structure: This is the physical equipment involved in the network eg router, cabling etc). Logical data structure: This is how the information flows internally and externally (the transfer of information from one node to another on the network).
What is a complex data structure?
A complex data structure is the kind of structure that has two arrays. One array hols the real part of the complex data and the other array holds the imaginary part.
Is a linked list a physical data structure?
Physical data structures are how data is organized on a hardware storage device, and therefore how they appear to the computer. Logical or virtual data structures are software-based objects, and how the user or program sees it. Although many file systems use a type of linked list format for storing information, a linked list is used for both hardware and software purposes, and therefore it cannot fall under either the physical or virtual data structure classification.

What is the difference between physical structure and logical structure of a disk?
Physical structure refers to the actual layout of data on the disk, including sectors, tracks, and cylinders. Logical structure refers to how the operating system organizes and accesses data on the disk, such as partitions, file systems, and directories.
Which data structure convert logical to physical address?
Linear data structure is used to convert the logical address to physical address .Stack is used in this and the various conversion such as postfix,prefix and infix notation are come in this
What do you mean by data independence?
the ability to modify the structure or schema of one level without affecting the other level is call data independence it is of two type physical data independence logical data independence

How are the internal external and conceptual schemas related to concept of logical and physical data independence?
The internal schema represents the physical storage structure of data, the external schema represents how different users view the data, and the conceptual schema defines the logical structure of the entire database. Logical data independence means that the conceptual schema can change without affecting the external schemas, while physical data independence means that changes in the physical storage structures do not affect the conceptual or external schemas.
Is it harder to achieve logical data independence or physical data independence?
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.

What is the difference between data and data structure?
Data structure: An information structure is an arrangement of information considered as one substance. An int, for instance, is a straightforward variable, can't be considered as an information structure, yet an exhibit is an information structure. Data: Information will be data that has been interpreted into a frame that is more advantageous to move or procedure.
