LAY-ten-see Delayed (slow) response time.

The delay between the time a device receives data and the time the data is forwarded out to the destination port.

Latency is a combination of time required to send information across a distance (usually close to the speed of light) and the processing time required at each end. High latency refers to a longer delay, while low latency refers to a shorter delay. When the latency is very low, the delay is not noticeable. This is especially significant in two-way communications such as teleconferencing.

The delay between a control being turned or a key being pressed and hearing the result in the output. Hardware synths have almost zero latency - but many software synths have a lag.

The time taken to service a request (deliver a message, for example, or retrieve information from a file system).. 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.

The delay between the time a device receives a packet and the time the packet is forwarded out of the destination port.

the very short delays created in the packaging, transmission, and acknowledgement of network data requests.

The read/write heads in a drive have to move from track to track on the disk and read or write information to individual sectors. Because the disk is spinning, once a read/write head is in position, there may be a very short delay before the targeted sector is under the head. This delay is known as the latency factor and values are given in milliseconds.

The amount of delay in a LAN or WAN. For basic data where a small delay can be tolerated, latency is usually not an issue. However, for communications services used for videoconferencing or VoIP for example, latency can interfere with the audio and/or visual communications. In shared bandwidth transmission environments, it is possible to encounter latency which varies dynamically, caused by perhaps a single user accessing or originating multi-megabyte-sized files or accessing high bandwidth streaming signals.

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 from the transmit request to the actual transmit as a result of packet processing (i.e. store, analyze, and forward). Also see jitter and throughput.

The speed of a network is dependent on both latency and bandwidth, with latency referring to the time needed for an IP packet to travel from source to destination. Wide bandwidth and low latency are preferable.

1) time it takes for a data packet to move across a network connection; 2) visible delay between request and display of content and ad. Latency sometimes leads to the user leaving the site prior to the opportunity to see. In streaming media, latency can create stream degradation if it causes the packets, which must be received and played in order, to arrive out of order.

The time it takes for a packet to reach it's destination. Higher delay times can be an issue, especially for VoIP, where voice delay can be recognized with latency higher than 150 milliseconds. Higher than 500 milliseconds and the conversation is going to be very problematic.

Edit / The amount of time that passes from the instant network content is first produced, until it first appears at the destination point. Interactive voice content requires very low latency because humans easily perceive it. A good example of perceivable latency in a voice connection is when you are speaking on an international long distance call, or when you are speaking cell phone to cell phone. The latency is the amount of time that passes from the time the speaker utters a word until the time the hearer first begins to hear it. See Also: QoS CoS VoIP

This refers to the time it takes for a packet of information to reach the client from the server. The server has a limited number of packets it can send out, and a large number of clients may be competing for them. Lag occurs when a connection slows down, so that everyone is synchronized into the same frame of time.

Internet applications that require quick responses, such as games, function poorly if a connection's latency is high.

The time it takes for a packet to travel from its point of origin to its point of destination. In telephony, the lower the latency, the better the communication. Latency has always been an issue with telephone communication taking place over exceptionally long distances (the United States to Europe, for example).

The time to send a zero-length message from one node of a concurrent processor to another. Non-zero latency arises from the overhead in initiating and completing the message transfer. Also called startup time.

Latency is also referred to as ping time, it is the time it will take a single packet of data to travel to a remote server, and return. Latency improves in proportion to line speed, (and faster speeds provide more bandwidth). Although, with a sufficiently small packet, the ping time is more a function of the number of hops between you and the remote server, congestion on the way, and so on. On a modem, ping time to your first hop (usually your ISP modem rack), is no better than 100ms (1/10th of a second). With larger packets, say, 2K, this could be around 1000ms (1 second) or more. Players of any internet interactive games know that latency is a key factor in deciding which game to join and how well it will play.

Latency also appears in MIDI equipment in different context: since MIDI interface is not really fast sometimes significant delay can occur when synchronizing audio components. That kind of latency is solved by delaying MIDI signals for particular time in milliseconds (ms).

This is the amount of time it takes a packet of data to move across a network connection. When a packet is being sent, there is "latent" time, when the computer that sent the packet waits for confirmation that the packet has been received.

(Excessive) response time. Time between sending a request to a server (e.g. Web page) and receiving the response.

(ISO) The time interval between the instant at which a CPU's instruction control unit initiates a call for data and the instant at which the actual transfer of the data starts. Syn: waiting time.

used to describe the period of time between the beginning of a chronic disease process and its detection or clinical presentation.

The time between initiating a request for data and the beginning of the actual data transfer. Network latency is the delay introduced when a packet is momentarily stored, analyzed and then forwarded.

The amount of time that it takes for a data packet to be transmitted from one endpoint to another.

Latency is measured as a calendar month average of all latencies between all components of the XO IP network. A customer can claim a violation billing credit one time for each latency violation that occurred in a calendar month. The total billing credits from all combined SLG violations will not exceed one month\222s MRC for a customer\222s service/product.

The time, expressed in quantity of symbols, taken for a signal element to pass through a device.

A temporal measure of response, referring to the time delay between the occurrence of the stimulus and the onset of the response. See also psychosexual development.

The time that elapses between issueing a request for data, and actually starting the data transfer. In a hard disk, this translates into the time it takes to position the disk's read/write head and ... more

The time it takes to read a disk (or jukebox), including the time to physically position the media under the read/write head, seek the correct address and transfer it.

Maximum acceptable delay between transmission and reception.

Latency is the technical term for the delays in computer systems caused by both distance and processing. Distance creates latency because of simple physics. Messages travel at the speed of light and over long distances the delays are measurable. Processing creates latency by delaying messages at every instance where a process occurs.

In Active Directory replication, the delay between the time an update is applied to a given replica and the time it is applied to some other replica. Latency is sometimes referred to as propagation delay. See also: replication; Active Directory; replica

The delay for traffic crossing a network, caused by queuing and switching delays in each device on the path.by queuing and switching delays in each device on the path.

The delay associated with the time it takes a packet to travel from entry point to exit point.

The amount of timing delay from an analog audio input (at the Tx) to an analog audio output (at the Rx). The amount of latency in a system is determined by several time-delaying mechanisms: analog-to-digital conversion, data compression, RF transmission of the data, data receive buffering, data de-compression, and digital-to-analog conversion. Latency is an input setting that is typically included as a feature in an audio product. Latency is typically measured in milliseconds (ms), with typical values range from 15 ms to 148 ms. A lower latency setting is typically desired for a home theatre surround sound application and a higher latency setting is typically desired for hi-fidelity audiophile application.

The time from the initiation of an operation until something actually starts happening (for example, data transmission begins).

n. The time required for a signal to travel from one point on a network to another. See also ping1 (definition 1).

Data access time due to disk rotation. In the modern disk drives, one revolution takes about 8 to 16 ms. Average latency of the disc is 8 or 4 ms.

Latency is a time delay between the moment something is initiated, and the moment one of its effects begins. The word derives from the fact that during the period of latency the effects of an action are latent, meaning "potential" or "not yet observed". Even within an engineering context, latency has several meanings depending on problem domain (i.e. communication, operational, or mechanical latencies).

A quiescent period during a disease process. In the HIV/AIDS disease process, clinical latency is an asymptomatic period in the early years of HIV infection. The period of latency is characterized in the peripheral blood by near-normal CD4 counts and HIV levels. Recent research indicates the HIV remains quite active in the lymph nodes during this period. Cellular latency is the period after HIV has integrated its genome into a cell's DNA but has not yet begun to replicate.

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 state in which a pathogenic organism is present in the body but not actively replicating or causing illness.

a QUIESCENT period during a disease process. Clinical latency is an ASYMPTOMATIC period in the early years of HIV infection. The period of latency is characterized in the peripheral blood by stable, slightly depressed CD4 CELL COUNTS and low HIV levels. Research indicates that HIV remains quite active in the LYMPH NODES during this period. Cellular latency is a condition that exists in some cells after HIV has integrated its GENOME into the cell's DNA but has not yet begun to replicate. Cellular latency may last for years, making the eradication of HIV from the body unlikely.

In order to increase their chances of survival and successful avoidance of the immune system, many viruses lie inactive for a defined period before reproducing within their host cells. Or, they many launch periodic infections and re-infections of a host over a period of years, even a lifetime.

The period when an organism is in the body, shows no symptoms, but is in an inactive state (also known as incubation period).
