a time interval between the stimulation and response

Latency is a time interval between the stimulation and response, or, from a more general point of view, a time delay between the cause and the effect of some physical change in the system being observed.

The time that elapses between request and response

The time that elapses between request and response is latency.

the time it takes for data to be transferred from one point to another

Note that latency is the time it takes for data to be transferred from one point to another, while network bandwidth pertains to the maximum amount of data that can be transferred wirelessly over a network in a given time.

the measure of delay on the network

Latency is a measure of delay in a network.

the time the time takes for devices to send and receive signals between each other

Latency is the time the time takes for devices to send and receive signals between each other.

the delay that is caused by the system

Latency is the delay that is caused by the system.

the time delay in transmitting or receiving packets on a network

Latency is the time delay in transmitting or receiving packets on a network.

the delay data experiences

Latency, measured in milliseconds, is the delay data experiences as the delay data experiences travels between points in the network.

the time required to transmit a packet across a network

Latency is the time required to transmit a packet across a network, and is highly dependent on your network topology.

a function of the distance between two points of transmission

Latency is primarily a function of the distance between two points of transmission, but also can be affected by the number and quality of the network or networks used in transmission.

a delay to the transfer of data

Latency, in computing terms, is the delay before a transfer of data begins following an instruction for an instruction's transfer.
