1 5 7 Packet Tracer Network Representation (Challenge Questions)

CCNA: Intro to Networks
Hi, guys I was unclear on 2:09 of this video and I did some corrections down below. Please take a look for a better understanding.
2:09:- PC5 can communicate within a local area network, but when it needs to talk to someone outside of LAN, it needs an IP address, subnet mask, and default gateway.
Also, stay tuned for upcoming exciting lab (packet tracer) activities.
