Difference between physical/logical/virtual memory address

Question

I am a little confused about the terms physical/logical/virtual addresses in an Operating System(I use Linux- open SUSE)

Here is what I understand:

Answer 1

Logical memory is relative to the respective program i.e (Start point of program + offset)

Virtual memory uses a page table that maps to ram and disk. In this way each process can promise more memory for each individual process.
