1. Traffic control: As the data communication is the most energy-consuming part of the wireless sensor networks by decreasing the amount of traffic, energy can be saved. To distribute traffic effectively from a central node to other nodes, investigations are still needed in the network. 2. Preserve the traffic load balancing:
Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
1- The electromagnetic spectrum is the range of all type of EM radiation. It also describes the wavelength of light. EM radiation is the radiant energy that is released by a certain electromagnetic processes and a wavelength is the distance between successive crests of a wave. 2- The different between ionising and non-ionising radiation is that ionising radiation carries energy to ionize atoms and has more energy than non-ionising.
1. Perception categories that significantly influenced walking frequency were landuse, and aesthetics and amenities. The safety, directness and continuity perception categories were not significant but had weak to moderate associations with land use and aesthetics perception. This implies improving perception of one category is bound to improve or negatively impact the perception of a correlated category. For example landuse perception was correlated with directness perception - which is intuitive, given that directness measured quick and easy access to land uses.
How frustrating to see these patterns of over and over and over. What and when will it take us to learn from past experiences of incident management? According to the PAF 561 Week, One Lecture Series by Professor Pete Smith, an emergency communication is integral and vital in all phases of emergency management, particularly during the response phase. Thus, a well-coordinated emergency response effort saves lives and protects property and the environment. And the opposite is more so true.

Chapter 2 Security and Encryption Introduction the process of preventing and detecting unauthorized using of your computer is called Computer security, prevention help to stop unauthorized users (also known as "intruder") from accessing computer system, detection determine where if someone attempted to break into system or not. Network security is the proper safeguarding of all components associated with a network. Security involves the various measures to protect network's components and resource from various threats including physical (e.g., natural disaster, sabotage) and illegitimate users. In generally, security is similar to safety, Security is the condition of being protected against danger and loss . Security issues associated with co-operative routing in multi-hop wireless networks they are as follows : • Confidentiality: The confidentiality property refers to limiting unauthorized access to sensitive information.
Privacy is an important right, it is a necessary condition for other human rights stated in the UNIVERSAL DECLARATION OF HUMAN RIGHTS which is common standard for all nations, and it included rights such as a person ’s right to freedom and dignity stated in article one. .
