Detailed explanation-1: -The frame is sent onto the network where an Ethernet switch checks the destination address of the frame against a MAC lookup table in its memory. The lookup table tells the switch which physical port, i.e., RJ45 port, is associated with the device whose MAC address matches destination address of the frame.

Detailed explanation-2: -The main difference between a packet and a frame is the association with the OSI layers. While a packet is the unit of data used in the network layer, a frame is the unit of data used in the OSI model’s data link layer. A frame contains more information about the transmitted message than a packet.
