Which data unit is the main focus of the network layer?
The network layer primarily handles the transmission of data in the form of packets 📦. It is responsible for routing these packets across different networks, ensuring they reach their destination efficiently. Unlike the physical layer, which deals with bits 💡, or the data link layer, which manages frames 📑, the network layer's primary concern is organizing and directing packets through the network. This involves determining the best path for the data to travel and managing packet delivery.
