CAS and RAS Latency are two ways of measuring speed
CAS (column access strobe) Latency and RAS (row access strobe) Latency
it depends on more then rotational speed. The Rotational speed and latency time is related as follows: Latency time = (1/((Rotational Speed in RPM)/60)) * 0.5 * 1000 milli seconds
delay to access the data in cache in context of processor's speed. Time to access the requested data in cache , at that time processor have to wait .. is called cache latency.
Latency is defined as the network speed in which the information being broadcast from the original server reaches the individual's device by measurement of milliseconds. This means that a lower latency will allow more information to be sent or received and thus, creating a better experience. Improving low network latency can be accomplished by establishing more latency-sensitive software so that multiple tasks and improved performance can occur.
A transcontinental fiber link might have many gigabits/sec of bandwidth , but the latency will also be high due to the speed of light propagation over thousands of KM.In constract a 56 kbps modem calling a computer in the same building has low bandwidth and low latency
The Latency ended in 2011.
The Latency was created in 2006.
The speed of memory is typically measured in megahertz (MHz) or gigahertz (GHz), indicating the frequency at which data can be accessed and transferred. Memory speed is also expressed in terms of latency, which represents the delay between when a memory controller requests data and when it is made available. Some common benchmarks for measuring memory speed include bandwidth tests and latency tests.
Lag is followed up by latency. If you detect latency but not lag, then someone else has it.
latency = transmit+propagation
Latency in PC memory refers to the delay between a request for data and the actual delivery of that data. It is typically measured in nanoseconds and is a critical factor in determining the overall speed and performance of a computer system. Lower latency means faster access to data, enhancing the responsiveness of applications and systems. Memory types like DDR (Double Data Rate) have specific latency ratings, influencing their effectiveness in various computing tasks.
Sleep latency-- The amount of time that it takes to fall asleep. Sleep latency is measured in minutes and is important in diagnosing depression.
