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.
The time it takes for a packet to cross a network connection, from sender to receiver. 2. The period of time that a frame is held by a network device before it is forwarded. Two of the most important parameters of a communications channel are its latency, which should be low, and its bandwidth, which should be high. Latency is particularly important for a synchronous protocol where each packet must be acknowledged before the next can be transmitted.
