The act of penetrating can range from harmless to malicious. Harmless hacking could be hacking into a college computer and copying some files in order brag to friends. Malicious hacking is more planned. Usually when hackers are malicious, it is because they are taking revenge on someone or they need to cover their tracks ... hacker include a prefix scanner, a terminal, a password cracker, and a virii maker. A prefix scanner dials every telephone number with a specific prefix and area code in order to find a carrier, another computer system that has a link to a network. A terminal is any program that allows you to connect to a network. A password cracker is a program that tries passwords from a giant list ...
- 132: The History and Development of Computers
- ... have on our lives and promises they hold for the future, it is important to understand their evolution. The abacus, which emerged about 5,000 years ago in Asia Minor, may be considered the first computer. This device lets users to make computations using a system of sliding beads arranged on a rack. But as the use of paper and pencil spread, the abacus lost its importance. It took nearly 12 ... would have a stored program and could perform calculations and print the results automatically. After working on the Difference Engine for 10 years, Babbage was suddenly inspired to begin work on the first general-purpose computer, which he called the Analytical Engine. Babbage's assistant, Countess of Lovelace was instrumental in the machine's design. She helped revise plans and communicate the specifics of the Analytical Engine to the public. Also, Lady Lovelace's understanding of the machine allowed her to create the instruction routines to be fed into the computer. Babbage's steam-powered Engine, may seem ancient by today's standards. However, it outlined the basic elements of a modern general purpose computer and was a breakthrough concept. Babbage borrowed the idea of ...
- 133: Escapism and Virtual Reality
- Escapism and Virtual Reality ABSTRACT The use of computers in society provides obvious benefits and some drawbacks. `Virtual Reality', a new method of interacting with any computer, is presented and its advantages and disadvantages are considered.

One of the most recent, and hence most rapidly absorbed periods, has been that of the computer. The Age of Computing began with Charles Babbage in the late 19th century Babbage , grew in the calculating machines between the wars EarlyIBM , continued during the cryptanalysis efforts of World War II Turing,Bletchley and ... length between other technological periods. The great strength of computers whether viewed as complex machines, or more abstractly as merely another type of tool, lies in their enormous flexibility. This flexibility is designed into a computer from the moment of its conception and accounts for much of the remarkable complexity that is inherent in each design. For this very reason, the uses of computers are now too many to ever ...

- ... wood and metal (he made his own pins, screws and switches), and sometimes had altimeter and barometric switches which would activate at precise altitudes in an airplane. Bombs, like the one planted outside of a computer store in Sacramento, were sometimes fitted with gravity triggers which would detonate the bomb at the slightest touch. Later bombs contained two independent systems of batteries and wires, a backup fail-safe mechanism, installed to ensure the bombs detonation. The crime scene analyses suggested that each bomb "took more than a hundred hours to construct" (Douglas, 56). The bombs were getting deadlier as the Unabomber's skill level evolved. FBI agent James Fox says "This guy ... explosion was so great that the pieces of Murray's body; when retrieved, filled eleven bags. Evidence was presented to the coroner in paint cans. Some bombs like the one that killed Hugh Sutton, a computer store owner, was filled with pieces of nails to maximize the devastation to the victim. He also became more devious by targeting either the person to whom the package was sent or the person ...

- Crimes Crime refers to many types of misconduct forbidden by law. Crimes include such things as murder, stealing a car, resisting arrest, possessing or selling illegal drugs, appearing nude on a public street, drunken driving, and bank robbery. The list of acts considered crimes is constantly changing. For example, at one time, people were charged with witchcraft, but this is no longer illegal. Today, it is becoming a serious crime to pollute the air and water. In colonial days, pollution received little attention because it caused few problems. During the 1700's in England it was not a crime for people to steal money entrusted to their care by an employer. Today, this type of theft, embezzlement, is a crime. Crimes may be classified in various ways. For example, they sometimes are grouped ...

(1) When Gibson coined that phrase he had no idea that it would become the household word that it is today. "Cyberspace now represents a vast array of computer systems accessible from remote physical locations." (Cavazos 2) The Internet has grown explosively over the last few years. "The Internet's growth since its beginnings in 1981. At that time, the number of host systems ... is the person behind the handle. Some sysops make the information public, or give the option to the user, or don't collect the information at all. The Internet brings forth many new concerns regarding crime and computers.
