Answer 3

netstat (network statistics) is a command-line tool that displays network connections (both incoming and outgoing), routing tables, and a number of network interface statistics. It is available on Unix, Unix-like, and Windows NT-based operating systems.

It is used for finding problems in the network and to determine the amount of traffic on the network as a performance measurement. [1]
