Question

differentiate between logical record and physical record

Answer 1

A physical record often is unstructured and has a fixed size related to the kind of physical media that stores it, and possibly to the location of the record on the media.

A logical record often is structured (has various program-specific fields) and might be stored in some number of full or partial physical records.

For example, a hard disk drive might be divided up into sectors (physical records) of 512 bytes each. If an application needs 1200 bytes of data for an address book entry (logical record) this will occupy portions of 3-4 sectors on disk.
