Data Link Layer INTRODUCTION: Now a day’s communication is vital for the entire world‚ nothing happens without communication. The cell radio communication and wireless computer networks of GSM (Global System Mobile)‚ CDMA (Code Division Multiple Access) type are worldwide communication systems. All these communication systems are based on the reference model OSI-RM (Open System Interconnection-Reference Model) Description of OSI-RM System: OSI-RM is an International Standard ISO that defines

Federalism in the United States has had several different concepts throughout our history. Dual federalism ran until around the Great Depression of the 1930s. Dual federalism has very distinct and rather clear lines of power for the national government as well as the state or local level of government. At times‚ it is referred to as “layered cake”. The national level very distinct and rule over much smaller‚ local‚ or state governments. There is a balance of power between the two‚ each maintains

again‚ while other feared the big “C”…Communism and the Soviet Union would attack. In order to rebuild the continent‚ leaders decided on one solution: the unification of Europe. What they couldn’t decide on was which path to take: federalism or functionalism. Federalism‚ on one hand‚ is the Big Bang Theory of Europe‚ the idea to rebuild the continent all at once. This comes from the notion of popular sovereignty. If there are European people‚ they can build an European government. This provokes

Layers of the Grand Canyon During the earliest periods of the Grand Canyon formation where we have Tapeats sand stone‚ bright angel shale and muav limestone it would appear that there was a relatively shallow‚ warm sea. This is indicated by the presence of Trilobite fossils found in this layer which thrived in that environment. Trilobites were early animals that had exoskeletons that are usually the only part of them that is preserved in the fossil record. They were marine bottom feeders who thrived

Ozone layer damage is one of them. The objective of this paper is to review the origin‚ causes‚ mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer. The chlorofluorocarbon and the halons are potent

the slurry to be placed on the glass plates. A guide allows the applicator (with an adjustable layer thickness gauge) to be pulled along the glass plates as the slurry is dispensed. Some practice is needed to get a continuous body motion pulling the applicator across the plates to get an even layer. The glass plates must be the same thickness and extremely clean. Any oil or grease will result in a poor layer. Handle the plates with rubber gloves when washing or rinsing. Care is also needed if the edges

contrary‚ in rigid pavements‚ wheel loads are transferred to sub-grade soil by textural Strength of the pavement and the pavement acts like a rigid plate (e.g. cement concrete roads). In addition to these‚ composite pavements are also available. A thin layer of flexible pavement over rigid pavement is an ideal pavement with most desirable characteristics. However‚ such pavements are rarely used in new
