1. ping: A Fundamental Network Diagnostic Tool

The ping command is a fundamental network diagnostic tool used to test connectivity between two devices on a network. It works by sending ICMP (Internet Control Message Protocol) echo requests to a specific destination and waiting for a response.

Here's how ping can be used for troubleshooting:

• Verify Connectivity: If a ping request is successful, it means that the target device is reachable and your network connection is working.
• Measure Network Latency: The time it takes for the ping request to reach the target and return a response indicates the network latency, which can provide insights into potential network slowdowns.
• Identify Network Problems: If ping requests fail, it suggests a network issue, such as a firewall blocking the connection, a routing problem, or a network outage.

Examples:

• ping www.google.com - Tests connectivity to Google's website.
• ping 192.168.1.1 - Tests connectivity to your router.
