Explanation

The Internet layer in the TCP/IP model corresponds roughly to the Network layer (Layer 3) of the It is responsible for logical addressing, routing, and packet delivery across networks. The protocols that operate at this layer include: IP (Internet Protocol) – provides logical addressing and routing. ICMP (Internet Control Message Protocol) – used for error reporting and diagnostics (e.g., ping, ARP (Address Resolution Protocol) – maps IP addresses to MAC addresses (used to deliver packets on local networks).
