ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available in a wide range of operating systems – including most embedded network administration software.
It displays network latency and network loss at intermediate hops between a source and destination. Because it displays the degree of packet loss at any given router or link , it can also be used to determine which routers or subnets might be having network problems.
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag , as it is known in gaming circles , refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.
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 other ...
The packet delivery time or latency is the time from when the first bit leaves the transmitter until the last is received. In the case of a physical link, it can be expressed as: Packet delivery time = Transmission time + Propagation delay
The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
Today's Strands game revolves around names with a double meaning. NYT Strands Spangram Hint: Is it Vertical or Horizontal? Today's spangram is vertical (bottom to top).
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.
