What is the purpose of the Network Layer in the OSI model?
  • Step 1: Understand that the OSI model has 7 layers, and the Network Layer is the third one.
  • Step 2: Know that the main job of the Network Layer is to send data from one device to another across different networks.
  • Step 3: Learn that the Network Layer uses logical addressing (like IP addresses) to identify devices on the network.
  • Step 4: Realize that the Network Layer decides the best path for the data to travel to reach its destination.
