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.
The data link layer typically adds physical addresses (also known as MAC addresses) to its Protocol Data Unit (PDU) to ensure that data is delivered to the correct device on a local network. Additionally, it often includes a CRC (Cyclic Redundancy Check) for error detection, ensuring the integrity of the transmitted data. Logical addresses and the original data payload are not added at this layer; logical addressing is handled at the network layer above it.
To calculate the physical address from a logical address, you can use the base address and offset. Add the base address to the offset to get the physical address. This process is commonly used in computer systems to translate logical addresses to physical addresses for memory access.

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
A MAC address is not considered logical; it is a physical address. It is a unique identifier assigned to network interfaces for communications on a local network segment and is hardcoded into the network hardware. Unlike logical addresses, such as IP addresses, which can change based on the network configuration, MAC addresses remain constant for a device's network interface.
