The Network Layer (Layer 3 of the OSI model) is responsible for routing packets between different networks using logical addressing (IP addresses).

Elaboration:

• Manages IP addressing, routing, and packet forwarding.
• Works with protocols like IPv4, IPv6, ICMP, and OSPF.
• Ensures packets reach the correct destination, even across different networks.

Example:

A router operates at the Network Layer by forwarding packets from one network to another using IP addresses.
