Description:

Ping sends ICMP Echo Request messages to a specified network host, allowing you to check connectivity and measure round-trip time.

Usage:

Open the Command Prompt and type "ping <host>" (replace <host> with the target IP address or domain name) to execute the command.

Purpose:

It assists in troubleshooting network connectivity issues and assessing network performance.

3. tracert: Tracing the Network Route

Description:

Tracert traces the route taken by network packets from your computer to a destination IP address or host.

Usage:

Open the Command Prompt and type "tracert <host>" (replace <host> with the target IP address or domain name) to execute the command.

Purpose:

It helps identify network bottlenecks, diagnose latency problems, and pinpoint the source of connectivity issues.

4. netstat: Monitoring Network Connections and Ports
