Which command is used to check network connectivity in Windows?

• A. ipconfig
• B. ping
• C. tracert
• D. netstat

Answer: (B)

The command used to check network connectivity in Windows is the ping command. When executed, it sends Internet Control Message Protocol (ICMP) echo request packets to the specified network host. If the host is reachable, it responds with echo reply packets, thus confirming that connectivity exists between the two devices. This command is particularly useful for troubleshooting network issues, as it can help determine if a remote system is operational and reachable over the network. In contrast, other options serve different purposes. For example, the ipconfig command provides configuration details for the network interfaces on a Windows machine, including IP addresses, subnet masks, and default gateways, but it does not directly test connectivity. The tracert command is used to trace the route that packets take to reach a specific destination, providing a path view of the network but not directly testing connectivity. The netstat command displays network connections, routing tables, interface statistics, and other network-related data, focusing more on the current state of the network than connectivity testing. Hence, ping is the best choice for checking network connectivity specifically.
