    In networking, a packet is a small segment of a larger message. Data sent over computer networks*, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them. Suppose Alice is writing a letter to Bob, but Bob's mail slot is only wide enough to accept envelopes the size of a small in...

An IP header contains important information about where a packet is from (it...

    Network traffic is a term that refers to the packets that pass through a network, in the same way that automobile traffic refers to the cars and trucks that travel on roads. However, not all packets are good or useful, and not all network traffic is safe. Attackers can generate malicious network traffic — data packets designed to compromise or over...
