Microwaves
1. Microwaves are a form of radiant energy. Other common forms are radio waves, visible light, infrared heat and electricity. All forms of radiant energy are a part of the electromagnetic spectrum. To distinguish between the forms, they are classified according to the wave length which may vary from miles to thousandths of an inch.
2. Microwaves are located in the non-ionizing portion of the energy spectrum between radio waves and visible light. The first application of microwaves was in radar during World War II. Today microwaves are widely used in communication systems, radar and many other commercial and industrial applications.
3. Significantly large segments of the population are exposed to infrared rays, visible light waves and microwaves every day. One characteristic of microwaves is their ability to bounce or deflect off metal surfaces, a characteristic basic to its use in radar. Another is its thermal or heating effect utilized in microwave cooking.
4. The difference between microwave energy and other forms of ionizing radiation, such as X-rays, Alpha, Beta and Gamma rays, is that microwave energy is non-ionizing. In other words, it does not alter the molecular structure of the item being heated. The effects of microwave energy are strictly thermal and do not cause cellular change as with ionizing radiation.

Technology
1. Technology is the usage and knowledge of tools, techniques, and crafts, or is systems or methods of organization, or is a material product of these things. The word technology comes from the Greek technología meaning craft and the study of something, or the branch of knowledge of a discipline. The term can either be applied generally or to specific areas.
2. Technologies significantly affect human as well as other animal species ability to control and adapt to their natural environments. The human species use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. 3. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.

Society has only recently addressed the problems of crimes made possible by the computer revolution.
One problem involves the stealing of valuable information from other persons’ computers. Recall that larceny is “the wrongful taking of the property of others”. This traditional definition of the crime made it difficult to prosecute those who steal computer data for two reasons. First, many courts concluded that there was not a “taking” if an intruder merely copied the information in the computer. Second, even if an intruder copied and erased computer information, some courts concluded that there was no taking of “personal property” but only the loss of electrical impulses, which no one really owns.
