n The amount of time that passes before something starts to happen An important consideration in performance evaluation, where high throughput computer devices often postpone tranfers due to protocol transaction overhead, contention and other factors
The delay or time span between the voice being digitalized at the senders Location and then output at the receivers end is the latency of a connection Latency is influenced by the distance the data has to travel, the packet size, the number and delay time of network elements between the terminals and of course the latency generated by the terminals themselves when sending, receiving, encoding, decoding and compensating jitter
The delay time between the end of one communication and the start of another During this time, the processes associated with the communication are hung up and cannot continue Software engineers work to reduce latency to a minimum
Time it takes a packet to travel from source to destination Latency and bandwidth define the speed and capacity of a network
Of a computer: the time required to establish communication with a specific storage location, not including transfer time; equals access time less word time
{i} being hidden, being out of sight; latency stage (Psychology); retrieval time (Computers)
(computer science) the time it takes for a specific block of data on a data track to rotate around to the read/write head
The time between transmission and reception of data across a network On the Internet, latency is due to delays in routing equipment, collisions on the network backbone, and congestion in the exchange points between backbone service providers (amongst other things) Latency can lead to unacceptable performance across VPNs, especially for distributed database applications and multimedia protocols
Time between the initiation of the data transfer in the sending process and the arrival of the first byte in the receiving process
being present but not evident In HIV Disease, the virus is present for years before any symptoms appear During this period of latency, the virus is still active and damaging the immune system
The time taken to start up an operation Typically message latency is the time delay incurred between one processor starting a message send operation, and the recipient processor completing the receive operation Startup latency is the constant commicationn overhead incurred in sending a zero length message Communication networks are often rated in terms of latency and bandwidth Typical values of startup latency: 1 millisec between workstations connected by Ethernet, and 40 microsec with PVM on the Cray T3D MPP computer
With computers - the time lag between a request and the action being performed Latency can reflect network time delays or MIDI and audio playback timing errors See the section on soundcard latency Back
Any delay introduced into the network that prevents packet forwarding at wire speed
(n ) The time lapse between an SBus master's request of the bus and the completed transfer
Time taken to deliver a packet from the source to the receiver Includes propagation delay (the time taken for the electrical or optical signals to travel the distance between the two points) and processing delay Due to the distance to a satellite and back (over 34,000km each way), the latency when communicating via a satellite connection is at least 270 milliseconds, making interactive services difficult, compared to a delay of about 10 milliseconds across Europe via fibre
(n ) The time taken to service a request or deliver a message which is independent of the size or nature of the operation The latency of a message passing system is the minimum time to deliver a message, even one of zero length that does not have to leave the source processor; the latency of a file system is the time required to decode and execute a null operation See also startup cost
The delay incurred by a switching or bridging device between receiving the frame and forwarding the frame
