When you download a file from the internet, the data is transmitted as packets from the server. When data is transmitted from one device to another, it is divided into smaller units known as packets.

Now that you understand the OSI model, let's look at network packets. If you want to read more about the OSI model, check out this comprehensive essay. The OSI Model classifies network architecture into seven layers:Īpplication, Presentation, Session, Transport, Network, Datalink, and Physical. The Open Systems Interconnection (OSI) paradigm standardises the manner in which two or more computers communicate with one another. While most security systems are command-line-based, Wireshark has an excellent user interface. Wireshark is now fully open-source, thanks to the global network engineering ecosystem. Most businesses and government agencies also use Wireshark as a primary network analyzer. Wireshark is compatible with all major operating systems. Wireshark was first made available in 1998.


Wireshark allows you to dissect network packets at a microscopic level, including detailed information on individual packets. Wireshark is a network analyzer that allows you to see what is going on with your network.
