A logical address is connected to a physical or MAC address using the ARP protocol. It operates on the OSI model's data link layer. The 12-digit number is 48 bits long, the first 24 bits are utilized for the OUI(Organization Unique Identifier ), and the remaining 24 bits are used for NIC/vendor-specific information. Since it is globally unique, two devices cannot share the same MAC address. Each device that may connect to the internet has one assigned to the NIC(Network Interface Card). Both an IP address and a MAC address are required for two networked devices to communicate with one another. The physical address used to identify each device on a network is called a MAC(Media Access Control) address.

We will also glance through the differences between MAC address and IP address.

We will also see how to find the MAC address of a device.We will also read why should the MAC address be unique in a LAN network.We will also cover the types of MAC addresses.We will also learn about the architecture of MAC.This article defines MAC addresses and the reasons to have both IP and MAC addresses.

It is also known as Physical address, hardware address, or BIA (Burned In Address). It is assigned to the NIC (Network Interface card) of each device that can be connected to the internet. A physical address that operates at the Data Link Layer is called a Media Access Control Address. To make communication between two networked devices, we need two addresses: IP address and MAC address. MAC address is the physical address, which uniquely identifies each device on a given network.
