ping

ping is a basic network tool available on practically every system. It allows you to test the connectivity of a network device or server. It does so by sending a series of ICMP (Internet Control Message Protocol) packets to the target host and reports the round-trip time, packet loss, and other statistics. The ping command is useful for troubleshooting network connectivity issues and measuring network performance.
