2. What is Packet Tracer?
Packet Tracer is a protocol simulator developed by Dennis Frezzo and his team at Cisco Systems.
Packet Tracer (PT) is a powerful and dynamic tool that displays the various protocols used in networking, in either Real Time or Simulation mode. This includes layer 2 protocols such as Ethernet, layer 3 protocols such as IP, ICMP, and ARP, and layer 4 protocols such as TCP and UDP. Routing protocols can also be traced.
