Important Key Points:
1. Internet Protocol ( IP) operates at this layer, enabling device communication between networks.
Knowledge Booster:
· Transport layer: Manages end-to-end data delivery but not routing between networks.
· Data link layer: Ensures communication within the same network (local or adjacent).
· Application layer: Facilitates user-level services like web browsing or email, not routing tasks.
