A router connects one network to another network.
What does a router use to move packet?

routing tables
What is Random Access Memory (RAM)
4.1.1.3
Provides temporary storage for various applications and processes
What is Read-Only Memory (ROM)
4.1.1.3
Provides permanent storage for bootup instructions, basic diagnostic software
What is Non-Volatile Random Access Memory (NVRAM)
4.1.1.3
Provides permanent storage for the startup configuration file (startup-config). NVRAM is non-volatile and does not lose its contents when power is turned off.

4.1.1.6
Process switching
Fast switching
Cisco Express Forwarding (CEF) - is the most recent and preferred Cisco IOS packet-forwarding mechanism. Like fast switching, CEF builds a Forwarding Information Base (FIB), and an adjacency table.
