[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.

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.
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.
The original DARPA Internet Protocol's RFC describes [1]: §1.4 TTL as: . The Time to Live is an indication of an upper bound on the lifetime of an internet datagram.It is set by the sender of the datagram and reduced at the points along the route where it is processed.
Ping operates by means of Internet Control Message Protocol (ICMP) packets. Pinging involves sending an ICMP echo request to the target host and waiting for an ICMP echo reply. The program reports errors, packet loss , and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard ...
A ping flood is a simple denial-of-service attack where the attacker overwhelms the victim with ICMP "echo request" packets. [1] This is most effective by using the flood option of ping which sends ICMP packets as fast as possible without waiting for replies.
The spike-triggered averaging (STA) is a tool for characterizing the response properties of a neuron using the spikes emitted in response to a time-varying stimulus. The STA provides an estimate of a neuron's linear receptive field. It is a useful technique for the analysis of electrophysiological data.
The biologically inspired Hodgkin–Huxley model of a spiking neuron was proposed in 1952. This model describes how action potentials are initiated and propagated. . Communication between neurons, which requires the exchange of chemical neurotransmitters in the synaptic gap, is described in various models, such as the integrate-and-fire model, FitzHugh–Nagumo model (1961–1962), and ...
