How does arpanet worked?

ARPANET, developed in the late 1960s, was the first packet-switching network and the precursor to the modern internet. It operated by breaking data into packets, which were then transmitted independently over a network of interconnected nodes using various routing protocols. Each packet contained destination information, allowing it to be routed through the most efficient path available, and once all packets arrived, they were reassembled at the destination. This decentralized approach enhanced reliability and efficiency, enabling multiple computers to communicate simultaneously.
