Answer / Alok Kumar Ranjan

A router is a networking device that forwards data packets along networks. It connects multiple networks, such as a LAN (Local Area Network) or the internet, and determines the optimal path (route) for each data packet to reach its destination based on network topology and routing protocols.nnWhen a router is compromised, an unauthorized user gains control over it, often through a security vulnerability. A compromised router can be used to launch cyber attacks or intercept and eavesdrop on network traffic.nnPacket loss occurs when one or more data packets fail to reach their intended destination during network transmission. This can happen due to various reasons such as congestion, poor signal quality, or hardware failure.nnPacket dropping refers to the deliberate discarding of data packets by a router or other networking device. Packet drops can occur due to network congestion or configuration issues. However, malicious packet drops can be used for denial-of-service attacks.nnA malicious packet is a data packet that contains harmful code or information with the intent to disrupt or exploit a computer system or network. Malicious packets can be used in various cyber threats such as viruses, worms, and Trojans.
