Difference Between Physical Address And Logical Address In Computer Networks

In simple terms cpu generates the logical address or virtual address. Mmu is a hardware device that maps virtual to physical address.

After identifying the network physical address is used to identify the host on that network.

Difference between physical address and logical address in computer networks. Moreover it is like how computer networks are linked to each other. Computer network network topology. The logical address is a 32 bit ip address that is not embedded in the network card but it is assigned to it for the purpose of routing between networks.

The physical address is the local address of a node. The mac or ethernet address is associated with layer 2 data link of the osi model. I am complete python nut love linux and vim as an editor.

From the perspective of a program that is running an item seems to be located at the address provided by the logical address. The key difference between logical address and physical address is that cpu generates logical address during program execution whereas the physical address is a location in the memory unit. The port address is used to identify the particular application running on the destination machine.

The internet protocol ip in combination with transmission. The basic way of differentiating between these two addresses is that logical address is the address of something that the central processing system generates in perspective of a program while the physical address is the actual address of something that the memory management unit computes. Through logical address the system identify a network source to destination.

Routing tables used by. Hope this discussion on the difference between physical and logical topology helps you to get the things in a better way. The set of all logical addresses generated by cpu for a program is called logical address space.

In network terms the address that you need is called a logical address. This type of address operates at layer 3 network of the osi model. This type of address is unique referred to as the ethernet or hardware address and cannot be changed but can be spoofed.

It is used by the data link layer to deliver data from one node to another within the same network. The logical address is generated by the central processing unit cpu whereas physical address is computed by memory management unit mmu. Physical and logical addresses are same in compile time and load time addressing binding schemes.

The logical address defines the sender and receiver at the network layer and is used to deliver messages across multiple networks. If you have any doubt feel free to write in the comment section. An ip address of the system is called logical address.

On the other hand the physical address is a location that exists in the memory unit. The basic difference between logical and physical address is that logical address is generated by cpu in perspective of a program. In an earlier post.

The key difference between physical addresses and logical addresses is that although physical addresses are scattered randomly around the world logical addresses follow a pattern determined by network administrators and stored in routing tables.
