Address Resolution Protocol (ARP)
ARP is primarily used to translate IP Addresses to Ethernet MAC Addresses.
The IP protocol identifies both the logical host as well as the logical network addresses...........
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.
Layer 3 network addresses are logical addresses and can be easily changed by software.

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.
IP address are the unique address. IP or internet protocol addresses are also known as logical addresses . The 32 bit address is the IPV4 address.
Linear data structure is used to convert the logical address to physical address .Stack is used in this and the various conversion such as postfix,prefix and infix notation are come in this
Physical address refers to the actual location of data in memory hardware, while a logical address is a virtual address that the CPU uses to access memory. Physical addresses are unique and specific to a particular memory location, whereas logical addresses can be mapped to different physical addresses by the memory management unit.
The Intel Pentium supports pure segmentation and segmentation with paging. The processor creates logical addresses, which are mapped to physical addresses by the segmentation unit. Those addresses may point to physical addresses within memory or paged swap space.
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.
