What is Internet?
The Internet layer of the TCP/IP model corresponds to the Network layer of the OSI model and is responsible for logical addressing and routing packets across networks. The primary protocol at this layer is IP (Internet Protocol), which assigns addresses to packets and determines how they are routed toward their destination. ICMP and ARP also operate at this layer.
