Which protocol is used to handle delivery of information from one network to another?

The protocol that is used to handle the delivery of information from one network to another is the Internet Protocol (IP). It is fundamental for routing packets across networks and ensuring that data can travel from the source to the destination, regardless of the underlying hardware or transmission medium.

While Transmission Control Protocol (TCP) is essential for ensuring the reliable transmission of data by establishing a connection between two endpoints, it operates on top of IP. TCP manages data integrity, ordering, and flow control but does not itself handle the routing of the data between networks.

File Transfer Protocol (FTP) is designed specifically for transferring files between systems but does not handle the delivery of information across networks in general. Similarly, Hyper Text Transfer Protocol (HTTP) is used for transferring web pages and related content but is not responsible for the core duties of routing data across different networks.

Therefore, the correct choice is the Internet Protocol, which provides the foundational layer for network communication.
