What is logical and physical address in microprocessor?
Logical Address is generated by CPU while a program is running. The logical address is virtual address as it does not exist physically, therefore, it is also known as Virtual Address. Physical Address identifies a physical location of required data in a memory.
What is the physical address of a computer called?
MAC address
Introduction to Physical Address. In computer networks, the MAC address (an acronym for Media Access Control) is an identifier for devices. It is a 48-bit identifier consisting of 6 hexadecimal blocks that uniquely corresponds to a network card or device. It is also called as the physical address.
What is virtual address and physical address?
Physical addresses refer to hardware addresses of physical memory. Virtual addresses refer to the virtual store viewed by the process. only a portion of the address space that processes do use is loaded into physical memory at a time.
What is physical addressing in data communication?
In computing, physical address refers to a memory address or the location of a memory cell in the main memory. It is used by both hardware and software for accessing data. A hardware component known as the memory management unit (MMU) is responsible for translating a virtual address to a physical address.
What is another name for physical address?

What Does Physical Address Mean? In IT, a physical address refers to either a memory location, identified in the form of a binary number, or a media access control (MAC) address. A physical address is also known as a binary address or a real address.

Where is physical address in microprocessor?
To get total physical address, put the lower nibble 0H to segment address and add offset address. The figure shows the formation of 20-bit physical address. Suppose the Data Segment holds the Base Address as 1000h and the data you need is present in the 0020h memory location (Offset) of the Data Segment.
How can physical address in 8086 microprocessor give an example?
I learnt that the physical address is calculated by shifting the segment address (16-bit) left 4 times and adding it with the 16-bit offset address. The memory in the 8086 architecture is 1M.
Why do we use physical addresses?
In computing, physical address refers to a memory address or the location of a memory cell in the main memory. It is used by both hardware and software for accessing data. Software, however, does not use physical addresses directly; instead, it accesses memory using a virtual address.
