A huge variety of networking hardware and software appeared. One challenge was to enable these different networks to communicate with each other. ARPA accomplished this by developing the , which created a true "network of networks," the current architecture of the Internet. Group of answer choices Network Protocol (NP) Web Protocol (WP) Internet Protocol (IP) ARPA Protocol (AP)

Internet Protocol (IP).

Explanation:

The principal communications protocol in the Internet protocol suite for relaying datagrams over network boundaries  is the Internet Protocol (IP). Its routing function enables internetworking, and importantly establishes the Internet.

The IP has the task of delivering packets from the source host to the destination host majorly based on the IP addresses in the packet headers. Due to this reason, the IP defines packet structures that contains the data to be delivered. It also defines methods of addressing that are used to label the datagram with source and destination information.
