Which router components and operations are correctly described?

Router components typically include the CPU, memory (RAM and ROM), interfaces (Ethernet, WAN ports), and power supply. Key operations involve packet forwarding, routing table management, and traffic filtering, which are essential for directing data packets to their intended destinations efficiently. Additionally, routers perform NAT (Network Address Translation) and may implement security features like firewalls. Overall, these components and operations work together to ensure reliable and secure data transmission across networks.
