The 7 Layers of the OSI Model Last updated: March 03‚ 2008 The OSI‚ or Open System Interconnection‚ model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next‚ starting at the application layer in one station and proceeding to the bottom layer‚ over the channel to the next station and back up the hierarchy. |Application |This layer supports application and end-user processes.

It is tri atomic oxygen (03) and is a gas found in the troposphere as well as in the stratosphere. Tropospheric ozone is undesirable since it is a pollutant these‚ causing photochemical smog and greenhouse effect. In the stratosphere‚ it acts as a protectant since‚ (i) It absorbs the dangerous UV-radiations (ii) It helps to trap the weather pattern within the troposphere‚ by generating a temperative inversion in the stratosphere. Tropospheric ozone is increasing due to human activities‚ while

Discussion Using the Thin Layer Chromatography experiment‚ caffeine was found to be the most polar due to the fact that it stayed closer to the stationary phase. Caffeine contains four amine groups that are extremely polar as a result of the hydrogen bond and amide functional group. Acetaminophen was found to be the second most polar analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted

A Glance at the Session Layer of the OSI Model Throughout the history of networking‚ one model has stood the test of time for providing not only insight‚ but also a foundation by which all networking systems utilize in some form or fashion. The seven layers of the OSI model‚ which stands for Open System Interconnect‚ are: Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data link‚ and Physical. These layers are the framework for networking‚ because they represent the roadmap‚ rules‚ and

ROLE OF YOUTH IN OZONE LAYER PROTECTION Ozone layer plays a vital role in protecting animals‚ human beings and plants from ultraviolet radiation. Ozone layer is destroyed by a group of manufactured or human made chemicals such as chlorine bromine. These chemicals are called "ozone-depleting substances". Ozone layer is destroyed by some natural’s ways and some humane made activities. A single molecule of chlorine can break apart thousands of molecules of ozone. Chlorofluorocarbons the most widely

The ozone layer is a layer in Earth’s atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 97–99% of the Sun’s high frequency ultraviolet light‚ which is potentially damaging to the life forms on Earth.[1] It is mainly located in the lower portion of the stratosphere The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist
