Learn Wireshark with online courses and programs
What is Wireshark?
Wireshark is an open-source packet analyzer. A packet is a single message or a unit of data from a specific network protocol or web server. Wireshark catches these packets when they travel from your device to the internet and offers real-time network analysis. It can troubleshoot performance issues, latency issues, retransmission problems, and dropped packets in your network.
In addition, Wireshark lets users see the network's type, frequency, and latency, converting binary network traffic into a human-readable format. It also offers multi-platform capabilities; you can run it by installing Wireshark on Ubuntu, Windows, Linux, macOS, FreeBSD, NetBSD, or any other supported platform.Footnote 1
