What is the internet layer of the TCP IP model?

The internet layer of the TCP/IP model is responsible for routing packets across different networks, enabling communication between devices on diverse networks. It includes the Internet Protocol (IP), which provides addressing and packet forwarding, ensuring data is sent to the correct destination. Other protocols at this layer may include the Internet Control Message Protocol (ICMP) for error handling and diagnostics. Overall, the internet layer facilitates the fundamental connectivity of the internet.
