Explanation

A router uses the Internet Protocol to send packets across a network toward their destination.

A firewall provides perimeter security by filtering the packets that pass through it.

CERT-In is the organisation charged with reducing computer security problems and incidents.

The Transmission Control Protocol sets the rules for splitting a file into packets and reassembling it.

Router and firewall are devices, while TCP is a protocol and CERT-In is an agency.

TCP works with IP as the core pair that carries data reliably across the internet.
