What command can be used to display the MAC address of a device in Windows?

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

Answer: (C)

The command to display the MAC address of a device in Windows is "ipconfig /all." When this command is executed in the Command Prompt, it provides detailed information about the network configuration of all network interfaces on the device. Among the information displayed, the Physical Address is the MAC address, which is a unique identifier assigned to the network interface for communications at the data link layer.

Using this command is particularly useful for troubleshooting network issues, configuring networks, or identifying different devices on a local network. It also helps users verify their network settings, including IP addresses, subnet masks, and default gateways, alongside the MAC addresses of their network interfaces. This level of detail is essential for network management and monitoring.

The other commands listed serve different purposes. For instance, ping is used to test connectivity between devices, tracert traces the route packets take to reach their destination, and netstat displays current network connections and related statistics.
