your question is wrong.

it should be "can physical address and logical address be same"

answer is no

because logical address is the combination of page number and offset

whereas physical address is the combination of physical page[frame] and offset

What is meant by effective address in microprocessor?

Effective address is the final address generated by offsetting and indexing which is sent to the virtual translation logic. It is the address of the operand in the virtual address space of the process, but not necessarily the address of the operand in the physical address space of the computer. In the 8085, efffective/virtual address is the same as physical address, because there is no virtual addressing logic in the 8085. In the 8086/8088, effective/virtual address is the same as physical address, but only in real mode. For example, in the 8086/8088, if the EBX register contains 1000000H, then the instruction MOV EAX,[EBX+1234H] has an effective address of 10001234H.

How does the virtual address to physical address mapping work in computer systems?

In computer systems, the virtual address to physical address mapping works through a process called address translation. The operating system manages this mapping by using a page table, which stores the correspondence between virtual addresses used by programs and their corresponding physical memory locations. When a program accesses a virtual address, the operating system translates it to the corresponding physical address to retrieve the data stored in memory. This allows programs to efficiently access and manipulate data without needing to know the physical location of the memory.


Do I need a physical office in Malaysia?

Not necessary. Physical address is not mandatory when you have a valid virtual address that comes under the jurisdiction of Malaysian government. Virtual office concepts getting the attention nowadays.


What is the difference between virtual logical and physical address spaces?

The concept of a logical address space is simply involved the process of mapping the Logical addresses to their Physical Addresses . Logical addresses are generated by the CPU; also referred to as virtual addresses.while Physical Address is the actual address of the data stored on the physical device and mapped by MMU.


Which address is more important the physical address or the logical address?

In the 8086/8088 the physical address and logical address have the same importance, because they both relate to the address of the operand. It is true that the offset (logical) address is added to the segment address to determine the physical address, but the limitations of the architecture of the processor forces programmers to consider both.If you are talking about a virtual environment, however, such as in the 80286 or higher, then the logical address is more important than the physical address, because the logical address is the address of the operand, while the physical address is (somewhat) arbitrarily assigned by the operating system.


Why you need memory physical address and memory logical address?

Physical Address refers to Storage location on Physical Memory wheres Logical Addressing is used by Memory Managing Programs to refers addresses from Physical Memory and Virtual Memory.


What does physical address mean?

The physical address is the final address that is presented to the bus, at the pins of the microprocessor chip, to form the address of the desired item in memory.In the 8085, physical and effective addresses are one and the same.In the 8086/8088, the physical address is the effective address plus 16 times one of the segment registers.In higher level processors, such as the 80386 and beyond, the physical address is formed by lookup of the effective address in a page table to convert from virtual/effective address to physical, or linear, address.The effective/virtual address is the address generated by the instruction and the programmer, without regard to any underlying addressing scheme. This is the address used when considering the "programming model", in "user mode".


Is physical address the home address?

Yes, a physical address would the the same as a person's address of their home. An example of a non-physical address would be a PO Box address.


How do you obtain a Physical address before owning property in area?

You can rent a mailbox at a local post office or obtain a virtual mailbox service. Virtual mailbox services provide a physical address that can receive and manage your mail remotely. Alternatively, you can use a co-working space or a business center to obtain a physical address for business purposes.


The virtual memory addressing capability of 80386 is?

NONE! The 80186 was an advanced version of the 8086 but did not include support for virtual memory. It had a 64K physical address space. The 80286 was the first Intel CPU to support virtual memory but it's capabilities were limited.


Physical address and logical address?

A logical (or virtual) address is a reference to a memory location independent of the current assignment of data to memory; a translation must be made to a physical address before the memory access can be achieved. A relative address is the address expressed as a location relative to some known point, usually the beginning of the program. A physical address, or absolute address, is an actual location in main memory.
