Is virtual address space same as logical address space?
The logical address is virtual address as it does not exist physically, therefore, it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. The term Logical Address Space is used for the set of all logical addresses generated by a program’s perspective.
Which address binding generate identical logical and physical address?
The physical address is a location in the memory unit that can be accessed physically. Identical logical address and physical address are generated by Compile-time and Load time address binding methods. The logical and physical address generated while run-time address binding method differs from each other.
Is logical address are same as physical address Yes No?
The basic difference between Logical and physical address is that Logical address is generated by CPU in perspective of a program whereas the physical address is a location that exists in the memory unit.
Is physical address same as virtual address?

How is virtual address converted to physical address?
There are two ways to convert a virtual address to a physical address: by using the ! vtop extension, and by using the ! pte extension. For an overview of virtual address in Windows, see Virtual address spaces.
Why do we use both logical and physical addresses?
Logical address is used to reference to access the physical memory location. A logical address is generated so that a user program never directly access the physical memory and the process donot occupies memory which is acquired by another process thus corrupting that process.
