Physical Address
click -start click run type cmd type ipconfig/all it will display all the details of all the lan cards and their MAC adddress as Physical 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.
Chris doesn't give out his home address because why should anybody?
The low level addressing scheme used on Ethernet. The 48-bit destination Ethernet address in a packet is compared with the receiving node's Ethernet address.
The effective address is the address generated by the program, after all transformations, such as index registers, offsets, addressing mode, etc. have been made. The physical address is the address generated by the hardware, after performing whatever lookups through the page table, etc. have been made. The effective address, or virtual address, is the concern of the program. The physical address, or real address, is the concern of the operating system.
its different......basically.network contain hosts can be server or workstation each has unique adddress (thats ip address) to communicate each other
MAC addressing. IP addressing. port addressing. specific address.
In computer architectures, a logical address is the address at which a memory location appears to reside from the perspective of an executing application program. This may be different from the physical address due to the operation of a memory management unit (MMU) between the CPU and the memory bus. Physical memory may be mapped to different logical addresses for various purposes. For example, the same physical memory may appear at two logical addresses and if accessed by the program at one address, data will pass through the processor cache whereas if it is accessed at the other address, it will bypass the cache.
The structure of the question is meant to trick you because 'logical addressing' is being used loosely. Technically, IP is the CORE protocol responsible for logical addressing. ARP is the network layer protocol that is used to discover the identity(physical address) of a machine whose IP address you know. Very briefly, it does this by creating a database that maps the MAC address to the (hosts') logical address provided.
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".
