Which tool provides a GUI-based network protocol analyzer for capturing and analyzing raw frames?

• A. Wireshark
• B. tcpdump
• C. Windump
• D. Netcat

Answer: (A)

Capturing and inspecting raw frames with a visual, protocol-level breakdown is what this is about. Wireshark provides a graphical interface to capture packets from a network interface and then dissect every frame into a detailed protocol stack. You can see each packet’s metadata (time, source, destination, protocol), drill into the fields of Ethernet, IP, TCP/UDP, and many other protocols, and view both the decoded interpretation and the raw byte values. It also supports live captures, post-capture analysis, powerful display filters, stream reassembly, and exporting captures for later review. This combination of live capturing and in-depth, GUI-based analysis makes Wireshark the right tool for examining raw network frames. In contrast, tcpdump and Windump are command-line packet sniffers, and Netcat is a simple data transfer utility, not a protocol analyzer with a GUI.
