Latency is the amount of time (usually measured in milliseconds) that a packet of data takes to get from one point to another and then back in a round trip.

延迟是数据包从一个地点到另一个地点然后返回这一个来回所花费的时间(通常以毫秒计)。

A packet is a collection of data prepared for transmission in a specific way.

包是为以某种特定方式进行传送而准备的数据集合。

This packet of data (usually about four kilobytes of code) is then embedded within the file, and a digital watermark is inserted into the newly created space left behind by the compression process.

In recent weeks Dr Smith and Dr Sample, working with Scott Southwood, another researcher at the University of Washington, have built a weather sensor that measures temperature and light levels and sends a packet of data every five seconds by radio.

But it can deliver that smaller packet of data with a shorter turn around time (two hours instead of as much as two weeks) and the entry cost is low enough that scientists who have shied away from DNA sequencing could buy their own PGM.
