Why each option
`netstat` is the primary command-line tool used to display network connections, routing tables, interface statistics, and other network-related information, including network I/O.
`iostat` reports on CPU utilization and I/O statistics for local disks/storage devices, not network I/O.
`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, including bytes transmitted and received, which directly relates to network I/O.
`route` is used to view or manipulate the IP routing table, not to measure real-time network I/O.
`vmstat` reports on virtual memory, processes, block I/O, and CPU activity, but not specific network I/O statistics like bandwidth usage per interface.
