What is the network layer?

The network layer is a crucial component of the internet protocol suite and is responsible for routing data packets across different networks. It comprises various protocols that enable data transmission across diverse networks, including LANs, WANs, and the internet. The primary role of the network layer is to manage the logical addressing of devices and ensure that data packets are delivered to their intended recipients efficiently. It also provides services like fragmentation and reassembly to support the transmission of data across networks with different maximum transmission unit (MTU) sizes. Overall, the network layer plays a pivotal role in ensuring seamless and effective communication between devices across different networks.
