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. [1]
Queueing theory is the mathematical study of waiting lines, or queues. [1] A queueing model is constructed so that queue lengths and waiting time can be predicted. [ 1 ] Queueing theory is generally considered a branch of operations research because the results are often used when making business decisions about the resources needed to provide ...
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).
These operators can be roughly categorized as providing a basic process algebra, concurrency, and communication. Choice and sequencing – the most fundamental of algebraic operators are the alternative operator ( + {\displaystyle +} ), which provides a choice between actions, and the sequencing operator ( ⋅ {\displaystyle \cdot } ), which ...
In queueing theory, a discipline within the mathematical theory of probability, an M/M/1 queue represents the queue length in a system having a single server, where arrivals are determined by a Poisson process and job service times have an exponential distribution. The model name is written in Kendall's notation.
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
Process theories are used to explain how decisions are made [4] how software is designed [5] [6] and how software processes are improved. [7] Motivation theories can be classified broadly into two different perspectives: Content and Process theories. Content theories deal with “what” motivates people and it is concerned with individual ...
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 ...
