Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the network architecture?Distributed, packet-switched wide-area network
2. What is the key technological innovations?Packet switching, Interface Message Processors (IMPs), and the TCP/IP protocol suite
3. How did ARPANET help scientists?Scientists could share powerful computers and data from far away, so they didn't need to own a big machine for each project.
4. Why is ARPANET called the grandparent of the Internet?ARPANET invented many ideas that later became the Internet, like email, remote login, and the packet‑switching method that TCP/IP uses.

Packet Switching: A data transmission method that breaks information into small, independently routed packets.
TCP/IP Protocol Suite: The foundational set of communication protocols enabling internetworking and global data exchange.
Internetworking: The process of connecting multiple distinct computer networks to form a larger, unified network.
Interface Message Processor (IMP): The specialized routers used in ARPANET to handle packet switching and network connections.
