Wireshark is an open-source packet analysis tool primarily used for capturing and inspecting network traffic in real-time, allowing users to analyze protocols and troubleshoot network issues. In contrast, NetWitness Investigator is a commercial security tool focused on threat detection and incident response, providing advanced analytics, security monitoring, and visualization of network data. While Wireshark is more suited for detailed packet-level analysis, NetWitness emphasizes security and forensics, making it more tailored for cybersecurity professionals.
Computer networks would be packet switched whereas a phone network would be circuit switched. Obviously packet switched are going to be alot more reliable and apparantly cheaper and less harder on the environment.
Alone, Wireshark is not a significant threat. provided that no hubs are used on a network and switches are not attacked (see Macoff) then a user running wireshark will only see traffic from their own host (see micro-segmentation). Wireshark and other packet sniffing programs should only be used by administration staff on networks as traditional users have no legitimate use for them.
Paul baran was one of the three inventors of packet-switched networks, along with Donald Davies and Leonard Kleinrock.
The Internet is packet switched, meaning each individual packet is routed from the source to the destination separately, and possibly through different paths. An example of a circuit-switched network would be the telephone network, where a connection from one end to the other is created and maintained until the call is disconnected.

No, Ethernet is packet switched.
Here's from the N800 Manual: To use a packet switched data service in a cellular network, such as GPRS, select Packet Data. To use a circuit switched data service in a cellular network, such as HSCSD, select Data Call.

A protocol analyzer or packet analyzer is a hardware or software tool used to intercept digital communications occurring over a portion of a network. Examples of packet analyzers (hardware and software) products are: Wireshark (Ethereal) tcpdump Netscout snoop
there are several ways: using network packet analyst. using metasploit using wireshark using scanners ect
