Best 5 Free Network Analysis Tool

Best 5 Free Network Analysis Tool

Network analyzer is a tool used to analyze the properties of electrical circuits, especially those which are connected with the reflection and transmission of electrical signals known as scattering parameters. A Network Analysis Tool basically diagnoses specific problems that occurred in the computer hardware network and helps to explore it thoroughly. There are three types of network analyzers:

  • Port Scanners
  • Packet Analyzers
  • Hardware Scanners

A Packet Analyzer is required to display and capture messages in particular that are processed by the network card of your computer. Hardware scanners supervise the network in order to detect malfunctions or threats if any. Port scanner is used to search for interesting information available from other computers on the same network. Overall Network analyzer tools are required for the planning, supervision and regulation of projects as it depicts an x-ray vision of the network.
