Introduce

Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface. Packet Tracer makes use of a drag and drop user interface, allowing users to add and remove simulated network devices as they see fit. The software is mainly focused towards Certified Cisco Network Associate Academy students as an educational tool for helping them learn fundamental CCNA concepts. Previously students enrolled in a CCNA Academy program could freely download and use the tool free of charge for educational use.

You want to start a journey in the world of computer networking, or become a DevOps? For that you have to learn the basics of computer networks using Cisco Packet Tracer. Actually, there are other applications for computer network simulation, but this application is very easy and lightweight. With Packet Tracer too, you will be easy to continue Cisco Certification (CCNA, CCNP, CCIE).

Packet Tracer can be run on Linux, Microsoft Windows, and macOS. Packet Tracer allows users to create simulated network topologies by dragging and dropping routers, switches and various other types of network devices. A physical connection between devices is represented by a 'cable' item. Packet Tracer supports an array of simulated Application Layer protocols, as well as basic routing with RIP, OSPF, EIGRP, BGP, to the extents required by the current CCNA curriculum.

In addition to simulating certain aspects of computer networks, Packet Tracer can also be used for collaboration. Packet Tracer also allows instructors to create activities that students have to complete. Packet Tracer is often used in educational settings as a learning aid. Cisco Systems claims that Packet Tracer is useful for network experimentation.

What are you waiting for, for those of you who are curious about how it works, please download it for you to practice. It would be better if you can also take certification to increase your skills in the world of work. Thank you :)
