Can you name the third layer of the OSI model and its main functions?

The third layer of the OSI model is the Network Layer. Its main functions are:

• Routing: determining the path for data transfer between nodes in different networks.
• Logical addressing: such as IP addressing, which identifies devices in the network.
• Fragmentation and reassembly of packets for transmission across networks with different maximum transmission units.
• Traffic management and error control at the routing level. An example of a protocol operating at this layer is IP (Internet Protocol).
