May I ask if ping is useful

You can know if the network is working or not.

Pinging usually refers to the use of a computer network tool to ping to test the quality and response time of a network connection. Specifically, ping typically detects whether the network connection is healthy by sending a special packet (ping packet beam) to the target host and waiting for a response packet to be received from the target host. The results of the ping can display information about the network connection, such as network latency (i.e., ping value), packet loss rate, transmission speed, etc., which can help diagnose network problems and optimize network performance.

In addition to the common uses mentioned above, ping can also be used to test the quality and reliability of network equipment. For example, an administrator can ping the entire network to get an overall assessment of the quality and performance of the network connection. There is also a test method called connectivity testing, which usually uses a ping tool to check if a network device is working properly.

This test method is usually carried out during the idle hours of network equipment or servers to prevent business operations from being affected.

In practice, ping can also be used to detect the availability of certain addresses on the Internet. For example, when you fail to access a ** in the browser, you can use ping to test whether it is reachable. Based on the test results, you can tell if there is a network connection issue, or if the ** may be temporarily unavailable.

In general, ping is a widely used computer networking tool with many useful features and application scenarios. Whether you're an individual or a business user, it's possible to use ping in network connectivity testing and troubleshooting. <>

Dear, Hello, I'm honored to answer for you :p ing is a command used to test your computer's network connection. It sends an ICMP (Internet Control Message Protocol) return request to the specified IP address, and if it does not receive a reply, the connection is normal.

In communication, ping refers to the corresponding time when computers exchange information with each other, also known as "delay" or "response time". Generally speaking, the lower the ping value, the better the connection quality of the network, and the lower the network latency, the lower the connection quality. Ping is also a very important tool for network management and troubleshooting, as it can detect network failures, determine the presence and latency of network connections, and identify the presence and status of a network device.

In daily life, we also often use the ping command to test the response speed of the ** or server to evaluate the quality of service. [Wei Song argues and laughs] <>
