The time between Command Execution and Response is called ______(a) Granularity (b) Latency (c) Lag time
(c)
EXPLANATION:
Latency:
Latency is a measure of the temporal delay. Typically, in xDSL, latency refers to the delay in time between the sending of a unit of data at the originating end of a connection and the reception of that unit at the destination end.
In a computer system, latency is often used to mean any delay or waiting that increases real or perceived response time beyond the response time desired. Within a computer, latency can be removed or "hidden" by such techniques as prefetching (anticipating the need for data input requests) and multithreading, or using parallelism across multiple execution threads.
In networking, the amount of time it takes a packet to travel from source to destination. Together, latency and bandwidth define the speed and capacity of a network.
Granularity:
The extent to which a system contains separate components (like granules). The more components in a system or the greater the granularity the more flexible it is.
Granularity is a term often used in parallel processing to indicate independent processes that could be distributed to multiple CPUs. Fine granularity is illustrated by execution of statements or small loop iterations as separate processes; coarse granularity involves subroutines or sets of subroutines as separate processes. The more processes, the "finer" the granularity and the more overhead required to keep track of them. Granularity can also be related to the temporal duration of a "task" at work. It is not only the number of processes but also how much work each process does, relative to the time of synchronization, that determines the overhead and reduces speedup figures.
Lag Time:
Lag Time is the amount of time between making an online request or command and receiving a response. A primary goal of advertising network efficiency is to minimize lag time.
