What foundational method allows the Internet to reliably transmit data by breaking it into small, independently routed segments that are reassembled at their destination?

💡 Explanation:

Packet switching is the core method of data transmission on the Internet. Data is broken into small, standardized chunks (packets), each carrying the destination address. These packets can take different paths to the destination, improving efficiency and reliability, unlike older systems like circuit switching (used in traditional telephony).
