ABSTRACT : This Paper provides useful information about a queueing theory approach to congestion costs. We Develop some analytic queueing models like M/M/1 and M/G/1 based on traffic counts and we model the behavior of traffic flows as a function of some of the most relevant determinants. These models pave the way towards our research objective. The illustration of statistical data of real time traffic flow and a comparison of M/M/1 and M/G/1 model have been furnished using those results. In every respect this paper will definitely be the proper guidelines to the people in connection with traffic flow, time saving factor and pollution problem.

ABSTRACT : Communication is an art which people use for mutual understanding; it is an aspect of human nature, whatever we are, wherever we may be. If two persons are present, a sort of understanding begins to develop between them. Even if nothing is communicated verbally, there is an exchange at the prespeech level. This communication might be pleasant or unpleasant, or indifferent, but mere proximity encourages communication, and its aim at understanding. The word ‘communication’ has been derived from Latin word ‘communicare’which indicates ‘sharing’. Communication is, indeed, sharing; sharing of ideas and feelings between two or more persons.

ABSTRACT : Cloud Computing holds the potential to eliminate the requirements for setting up of highcost computing infrastructure for the IT-based solutions and services that the industry uses. It promises to provide a flexible IT architecture, accessible through internet for lightweight portable devices. This would allow many-fold increase in the capacity or capabilities of the existing and new software. In a cloud computing environment, the entire data reside over a set of networked resources, enabling the data to be accessed through virtual machines. Since these data centres may lie in any corner of the world beyond the reach and control of users, there are multifarious security and privacy challenges that need to be understood and taken care of. Also, one can never deny the possibility of a server breakdown that has been witnessed, rather quite often in the recent times. There are various issues that need to be dealt with respect to security and privacy in a cloud computing scenario.

ABSTRACT : Green computing or sustainability is not simply the operational energy consumption of computing equipment. Green computing must take the product life cycle into consideration, from production to operation to recycling. This study focuses on the production and the operation phases of the product life cycle and demonstrates what actions will result in overall carbon footprint reduction for personal and business computing under various operational conditions and environments. Energy consumption related to end-of-life product recycling is not discussed in this study and is not believed to have a significant impact on the validity of the sustainability analysis based on production and operation energy consumption and carbon footprint.

ABSTRACT : The wireless technology is designed as a short-range connectivity solution for personal, portable, and handheld electronic devices. Since May 1998 the Bluetooth has steered the development of the technology through the development of an open industry specification, including both protocols and application scenarios, and a qualification program designed to assure end-user value for Bluetooth products.Wireless technology has been regarded as a paradigm shifter in the process industry. With the success of wireless technologies in consumer electronics, standard wireless technologies are envisioned for the deployment in industrial environments as well. Industrial applications involving mobile subsystems or just the desire to save cabling make wireless technologies attractive.
