science fiction novel or a video game. Yet‚ that is what some researchers at NASA did a few years ago. Atmospheric physicists Paul Newman and Luke Oman built a simulation of the Earth’s atmosphere and then proceeded to strip away our protective ozone layer. Their computer model reproduced the chemistry and circulation of the air; natural variations in temperatures and winds; and minor changes in the energy received from the sun. Newman and Oman then added ozone-destroying chemicals to the atmosphere

Censored data & Truncated data Censoring occurs when an observation or a measurement is outside the range and people don’ t know the certain value. The value is always above or below the range that people set. However‚ truncated data means that because of the limits‚ such as time‚ or space‚ people lose some data. Truncation is to cut off the data. In other words‚ we have collected and use the data‚ but the data is not in the range we have. It is called censored data. We don’t use the data because

The 7 layers can be split logically into two subgroups. Layers 7 thru 4 focus on the end to end communication of data source and destinations. Layers 3 thru 1 are provide consistent communication between the network devices. An easier way of looking at the OSI model is dividing the upper layers (7‚ 6‚ 5) from the lower layers (4‚ 3‚ 2‚ 1). The upper layers deal with application issues and are implemented only in software. The highest layer‚ the application layer‚ is the closest to the end user
