Everest has always been a trophy, but now that almost 4,000 people have reached its summit, some more than once, the feat means less than it did a half century ago. Today roughly 90 percent of the climbers on Everest are guided clients, many without basic climbing skills. Having paid $30,000 to $120,000 to be on the mountain, too many callowly expect to reach the summit. A significant number do, but under appalling conditions.
Figure B18.5 shows the three latencies that impact the speed of decision making. These are data, analysis, and decision latencies. Data latency is the time duration to make data ready for analysis, i.e., the time for extracting, transforming, and cleansing the data, and loading it into the database.
Latency is also known as lag and delay. It is the time it takes for a signal to get from transmitter to receiver.The definition of latency varies. Some term it as the time taken for a round trip from transmitter to receiver and back again. Latency is a particularly big issue with Voice over Internet Protocol applications (Internet telephony).atency. Latency is the time it takes for a message to travel across a network, or over the Internet. The greater the period, the greater the latency. The factor is measured in milliseconds.
