what is seek time
Access time
Seek time:- it is the time required to move the disk arm to th required track.During the "seek time", an actuator moves the disk heads to the disk.The seek time is the time it takes a hardware device or software program to locate a particular piece of information.latency time :-it is the time it takes for the begning of the requirement sector to reader the head. Latency is the elapsed time from the moment when a seek for confirmation that the packet has been received.Latency and bandwidth are the two factors that determine your network connection speed....Latency is a time delay between the moment something is initiated
If you shopped for RAM put into your computer to make sure your gaming is the fastest it can be, then the lower the latency the faster the RAM. Latency is the time when the memory controller starts to grab a line of code, there is a delay and when RAM sends out the line of code there is another delay. The time is takes RAM to find and send code is called latency. So when shopping find RAM with the lowest latency.
Rotational latency time refers to the delay experienced while waiting for the desired sector of a rotating storage medium, such as a hard disk drive (HDD), to come under the read/write head. It is a component of access time, which also includes seek time and transfer time. The average rotational latency can be calculated as half the time it takes for one complete rotation of the disk. This latency is influenced by the rotational speed of the disk, typically measured in revolutions per minute (RPM).
Latency is calculated by measuring the time it takes for a data packet to travel from the source to the destination and back again, known as round-trip time (RTT). This can be done using network tools like ping, which sends a packet to a target and records the time taken for the response. Additionally, latency can be expressed as the time taken for a single trip (one-way latency), which can be estimated by dividing the RTT by two, assuming symmetric network conditions. Factors like network congestion, routing, and processing delays can affect the overall latency.
Sleep latency-- The amount of time that it takes to fall asleep. Sleep latency is measured in minutes and is important in diagnosing depression.
we have seek = 10-50 ms so , average seek = (10+50) / 2 = 30ms and the access time = seek + latency = 20 + 30 = 50 ms
