The data link layer performs the framing process. On the other hand, the Network layer performs fragmentation of the data and creates smaller chunks known as packets. Another major difference is that a frame includes the device’s MAC address while a packet includes the device’s IP address.
The term frame originated from networking specifically communication over serial lines where the sender “frames” the data which is a collection of bits by adding special characters before and after the transmitted data.
A Frame can be defined as a data unit used in the Data Link layer. A frame is consist of markers that depicts the start and end of the packet and addresses for sending and receiving.
A packet can be any small block of data sent across a packet-switched network. The term derives from character-oriented protocols that are added special start-of-frame and end-of-frame characters when transmitting packets.
A packet is the protocol data unit used in the network layer. The primary function of the Network layer is to deliver a packet from one logical address (IP address) to another. A packet is a solitary unit of data interchanged between two devices on a network. The router uses an IP packet header to send packets through the network from source to destination.
