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 for virtually all operating systems that have networking capability, including most embedded network administration software.
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.
Netcode is a blanket term most commonly used by gamers relating to networking in online games, often referring to synchronization issues between clients and servers.Players often infer "bad netcodes" when they experience lag or when their inputs are dropped.
A connection with mismatched MTU may work for low-volume data but fail as soon as a host sends a large block of data. For example, with Internet Relay Chat a connecting client might see the initial messages up to and including the initial ping (sent by the server as an anti-spoofing measure), but get no response after that. This is because the ...
This is a list of Internet exchange points by size, measured by peak data rate (), with additional data on location, establishment and average throughput.. Generally only exchanges with more than ten gigabits per second peak throughput have been taken into consideration.
[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.

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.
This definition of bandwidth is in contrast to the field of signal processing, wireless communications, modem data transmission, digital communications, and electronics, [citation needed] in which bandwidth is used to refer to analog signal bandwidth measured in hertz, meaning the frequency range between lowest and highest attainable frequency ...
