Logical adderess is expressed as the location relative to the beginning of the program. it is defined by the user of the microprocessor. no need for calculation.
physical adderess is defined as the actual location of the process in the main memory. it is allocated by the CPU.
Physical adderess=base address*10h+offset address
read memory management from **broken link removed**
the reason for multiplying with 10h or hardwired zero is the segmentation. every segment (having size of 64KB) in main memory starts from paragraph boundary. so when the CPU saves adderess this zero is not included.
