GNS3 is a Graphical Network Simulation program. You can easily operate devices such as Cisco Switch and Router on GNS3.
You can improve yourself and become a network expert by making network designs with GNS3. Since this network simulator is a constantly developed program, it is always useful to check for updates to have new features.
Although the operating logic of this program is very similar to the Cisco Packet Tracer program, the biggest difference between them is that Cisco IOS images can be used more comprehensively and in detail.
With this simulator software, you can use IOS images of real Cisco devices for network designs on your computer. In other software, IOS images have insufficient and limited features.
