[citation needed] The lower one's ping is, the lower the latency is and the less lag the player will experience. High ping and low ping are commonly used terms in online gaming, where high ping refers to a ping that causes a severe amount of lag; while any level of ping may cause lag, severe lag is usually indicated by a ping of over 100 ms.

RTT is a measure of the amount of time taken for an entire message to be sent to a destination and for a reply to be sent back to the sender. The time to send the message to the destination in its entirety is known as the network latency, and thus RTT is twice the latency in the network plus a processing delay at the destination.
Tools such as ping, traceroute, MTR and PathPing use this protocol to provide a visual representation of the path packets are taking, and to measure packet loss at each hop. [ b ] Many routers have status pages or logs, where the owner can find the number or percentage of packets dropped over a particular period.
Ping measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water. [1] Ping operates by means of Internet Control Message Protocol (ICMP) packets.
Graphical depiction of contributions to network delay. Network delay is a design and performance characteristic of a telecommunications network.It specifies the latency for a bit of data to travel across the network from one communication endpoint to another.
A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo replies.

In the case of a ping flood or a denial of service attack, it can be harmful to the reliability of a computer network. Messages can become duplicated in the network further increasing the load on the network as well as requiring an increase in processing complexity to disregard duplicate messages.
In computing, a ping sweep is a method that can establish a range of IP addresses which map to live hosts. The classic tool used for ping sweeps is fping, [ 1 ] [ 2 ] [ 3 ] which traditionally was accompanied by gping to generate the list of hosts for large subnets, [ 4 ] although more recent versions of fping include that functionality.
