Detailed explanation-1: -Latency is a synonym for delay. In telecommunications, low latency is associated with a positive user experience (UX) while high latency is associated with poor UX. In computer networking, latency is an expression of how much time it takes for a data packet to travel from one designated point to another.
Detailed explanation-2: -Rotational Latency-The time taken by a desired sector of the disk to rotate itself to the position where it can access the Read/Write heads is called Rotational Latency. Transfer Time-It is the time taken to transfer the data requested by the processes.
Detailed explanation-3: -Seek time is the time taken for a hard disk controller to locate a specific piece of stored data. Other delays include transfer time (data rate) and rotational delay (latency).
Detailed explanation-4: -Each instruction takes a certain time to complete. This is the latency for that operation. It’s the amount of time between when the instruction is issued and when it completes.
