The network devices then use the MAC address which they received from packet headers and deliver the packet to the intended recipient. When a device send data packets to another device on the same network, the data packet includes the MAC address of the intended recipient in the data packet header. These devices like routers and switches generally used to forward data packets between different devices on a network.
MAC address is used by network devices like routers and switches. In this section, we will be learning about how to find a MAC address of a Windows and Linux machine using Java.Ī device MAC address does not change. It is used by the data link layer to control access, ensure data integrity, and identify network devices.
NIC helps in creating a layer which helps in transmitting and receiving data between two devices.MAC address known as Media Access Control address is a unique identifier of NIC. Computers can connect to a network and communicate with other devices using a hardware or software component known as Network Interface Controller(NIC).
