Acquired (adaptive or specific) immunity is not present at birth. It is learned. The learning process starts when a person’s immune system encounters foreign invaders and recognizes nonself substances (antigens). Then, the components of acquired immunity learn the best way to attack each antigen and begin to develop a memory for that antigen.

In this paper we illustrate the meaning, definitions and importance of intelligent software agent by contrasting agents with objects. Agents are indeed considered to be an evolutionary step forward from objects. The paper is dedicated to visualize the importance and awareness of the agents and multi-agents and will give suitable examples on them.
There are many interesting works showing a methodological approach for Multi-Agent system development. These approaches must be compared to identify the best possible Multi-Agent methodology. Furthermore, this paper highlights the multi agents structure, methodologies and common applications and provide surveys that allow researchers/developers to determine the directions in which agent-oriented methodologies are best suited to achieve goals of a particular project or system. Agents provide software designers and developers with a way of structuring applications around autonomous, communicative components and offer a new and often more appropriate route to the development of complex computational systems, especially in open and dynamic environments.

A transmission system is used to send information from the source to the receiver as reliably as possible. The role of modulation is to adapt the spectrum of the signal to the channel (physical environment) on which it will be transmitted.

The implementation of e-learning system in higher education institutions as an emerged technology will not guarantee its adoption by faculty members. In fact, the existence of technology alone is not enough in encouraging knowledge sharing behavior among users. The purpose of this study is to analyze the relationship between the perception of an e-learning experience as an emerged technology in higher education and the willingness to share this knowledge with staff members with their students. We characterized staff members' perceptions of an e-learning experience as a new technology by including an individual's psychological state of readiness and acceptance of technology; and to also practice this new experience with their students as an individual behavior. Technology Readiness Index and Technology Acceptance Model were integrated in order to explore staff members' perceptions of technology. The practice of staff members of this new e-learning experience with their students was characterized by the knowledge sharing behavior. We analyzed the responses of 400 participants from staff members in higher education using structural equation modeling. The correlated results showed that staff member's positive attitude on the perception of e-learning could increase the practice of this knowledge with students. A sense of insecurity towards this new technology also led to an undesirable effect on the staff member's perceptions of the ease of use of e-learning. Therefore, maintain a high degree of discomfort and insecurity towards an e-learning experience hinders enormously staff member's to share this knowledge with their students.

The rising technology trends has turned each infrastructure to its new hazards. Present information policies designed are not readily equipped with up-to-date analysis or problems suffered throughout networks. This paper addresses not only technical security issues but also providing managerial solutions. It practically targets resources allocations keeping in new management issues with its technical adoption to available parameters. This technical solution provided; is strategic in its nature but with self assessment criteria. Now system reliability issues with security complexities can be targeted effectively.

Like other organisms, bacteria has to maintain their characteristics from generation to generation, yet at same time, exhibit variations in particular properties in a small proportion of their progeny. Though heritability and variations in bacteria had been noticed from the early days of bacteriology, it was not realized then that bacteria too obey the laws of genetics.
