Low latency refers to shorter time delays in computer systems or communication networks. It is usually used to refer to the time it takes for a network packet to travel from the sending computer to the receiving computer via a network connection.

Low latency refers to shorter time delays in computer systems or communication networks. It is usually used to refer to the time it takes for a network packet to travel from the sending computer to the receiving computer via a network connection. In other cases, it may refer to the time it takes for data to be imported and out of computer random access memory (RAM) to use ping tests are the most reliable method for calculating network communication latency. Calculating the delay on the computer network requires recording the time it takes for ping to reach its destination and return. This can vary by many variables, including time of day, network type, distance to destination, and more. Typically, a large number of pings are sent, and the delay is based on the average of the round trip time per ping. Low latency is very useful in many cases, but has nothing to do with the large-capacity transfer of data. A connection may only require a single connection to the host to download a large file, and the speed of the file does not depend on the time delay in communicating back and forth with the source. Therefore, it is more desirable to communicate repeatedly with the destination in VoIP (VoIP) communication, which is beneficial because voice data needs to be sent back and forth at extremely high rates to avoid session delays. The same is true for certain types of web applications, such as large-scale multiplayer online games (MMOs), where the client playing the game needs to be able to constantly update their position in the game throughout the game. Higher latency can cause latency to players in gaming performance. Since the server hosting the game cannot update the player's location as soon as possible, other web applications, such as those used by Japanese traders, have found that trading combinations can be updated and modified as soon as possible to keep up with the needs of certain high-frequency markets, thus having lower latency Although most latency discussions revolve around computer networks, specific hardware inside the computer can also benefit from low latency. Computer RAM is an example, the time required to add or delete data in a memory column can improve performance. This is called column address strobe (CAS) delay, and a device in a computer called a memory controller imports data into and out of specific columns in RAM. Some memory controllers are located on the computer motherboard, while others improve latency by implementing on a central processor (CPU). Another computer hardware implementation that improves latency is that some manufacturers use special device drivers on expansion cards to bypass the operating system. Audio software that is more compatible with these special device drivers can achieve lower latency when delivering sound from the program to the user's ears through the device.
