O que (quem) é rotational latency - definição

TIME REQUIRED FOR DATA TO TRAVERSE A NETWORK

Network Latency; Network latency; Communication latency; Internet delay

rotational latency

Rotational delay; Seek time; Disk access time; Rotational latency; Disk seek; Seek delay; Short stroking; Throughput (disk drive); Disk drive performance characteristics; Disk-drive performance characteristics; Data transfer rate (disk drive); Short-stroking; Short-Stroking; Hard disk rotational latency

The time for the start of the required sector on a disk to appear underneath the read/write head. The worst case is where it has just passed the head when the request is received. For a disk drive with N heads per surface, rotating at R revolutions per minute, the average rotational latency will be L = 30/NR seconds. Rotational latency is one component of access time.

Hard disk drive performance characteristics

Rotational delay; Seek time; Disk access time; Rotational latency; Disk seek; Seek delay; Short stroking; Throughput (disk drive); Disk drive performance characteristics; Disk-drive performance characteristics; Data transfer rate (disk drive); Short-stroking; Short-Stroking; Hard disk rotational latency

Higher performance in hard disk drives comes from devices which have better performance characteristics. These performance characteristics can be grouped into two categories: access time and data transfer time (or rate).

seek time

Rotational delay; Seek time; Disk access time; Rotational latency; Disk seek; Seek delay; Short stroking; Throughput (disk drive); Disk drive performance characteristics; Disk-drive performance characteristics; Data transfer rate (disk drive); Short-stroking; Short-Stroking; Hard disk rotational latency

<storage> The time it takes for a disk drive to move its head(s) from one track to another. The seek time depends on the power of the servo, the mass of the heads, the number of tracks traversed and the time taken to position the heads over the target track accurately enough to start data transfer. See also: average seek time, minimum seek time, {maximum seek time}. (1997-07-15)

Network delay

Network delay is a design and performance characteristic of a telecommunications network. It specifies the latency for a bit of data to travel across the network from one communication endpoint to another.^: 5 It is typically measured in multiples or fractions of a second. Delay may differ slightly, depending on the location of the specific pair of communicating endpoints. Engineers usually report both the maximum and average delay, and they divide the delay into several parts:

Processing delay – time it takes a router to process the packet header
Queuing delay – time the packet spends in routing queues
Transmission delay – time it takes to push the packet's bits onto the link
Propagation delay – time for a signal to propagate through the media

A certain minimum level of delay is experienced by signals due to the time it takes to transmit a packet serially through a link. This delay is extended by more variable levels of delay due to network congestion. IP network delays can range from a few milliseconds to several hundred milliseconds.
