Those protocol analyzers that are designed for packet analysis are called packet analyzers (packet sniffers, sometimes network analyzers). These software tools intercept and log network traffic traversing over a digital network or a part of a network through the process of packet capturing. The captured packets can then be analyzed by decoding the raw data of the packets and visualized via displaying various fields to interpret the content. Those packet analyzers that intercept traffic on wireless networks are called wireless analyzers (WiFi analyzers).
