Imagine you want to send a secret message to your friend who lives far away. You need to break down the message into small pieces, so that it can travel through the internet and reach your friend's computer. These small pieces are called packets.
Packet Tracer is a computer program that helps us simulate the internet and test how packets are sent and received by different devices like computers, routers, and switches. It's like playing with a LEGO kit, where you can build and connect different devices and see how they work together.
With Packet Tracer, you can create a network and send data packets between different devices. You can see how the packets are sent from your computer to the router, then to the switch, and finally to your friend's computer. By doing this, you can understand how the internet works in a simplified way.
Packet Tracer is often used by students who are learning about computer networking. It helps them visualize complex concepts and understand how different devices interact with each other in a network. By using Packet Tracer, students can design and test different types of networks and configurations without worrying about damaging real equipment or disrupting an existing network.
