... services, telebanking, teleconferencing, even the complex simulations of virtual reality. This souped-up television will itself be a powerful computer. This, many believe, will be the world's biggest media group, letting consumers tune into anything, anywhere, anytime. The most extraordinary thing about the boom, is that so many moguls are spending such vast sums to develop digital technologies, for the delivering of programs and services which are still largely hypothetical. So what is behind such grand prophecies? Primarily, two technological advances known as digitization (including digital compression), and fibre optics. Both are indispensable to the high-s ...
... developed the first ÒwirelessÓ radio transmitter and receiver. Working at home with no support from his father, but plenty from his mother, Marconi improved upon the experiments and equipment of Hertz and others working on radio transmission. He created a better radio wave detector or cohere and connected it to an early type of antenna. With the help of his brothers and some of the neighborhood boys he was able to send wireless telegraph messages over short distances. By 1899 he had established a wireless communications link between England and France that had the ability to operate under any weather conditions. He had sent trans-Atlantic messages by late 1901, ...
... business. Before computers companies used to advertise only on magazines, billboards, and T.V. The internet has spawned a new world for advertising. If anyone has ever been on the Internet; they know that it is a major contributor to this. Instead of companies paying around 1 million dollars to advertise for a 30 second commercial during the Super Bowl; they could just pay a certain amount to be advertised forever on the net. People can also notice the changes of advertising on the T.V., also. Not until the last few years have people noticed that a great deal of the commercials on T.V. are computer-related. These two combined have made the advertising busin ...
... to check for changes in the current when the key is pressed the processor finds that the current has increased and reacts accordingly and the same when the current is depressed and the current decreases. Over the years many new types of keyboard have been thought up these are mostly more ergonomically designed than there older counter parts this is done in order to reduce R.S.I a problem that effects a lot of typists One of the most interesting keyboard is a device called a data hand this will take a combination of hand movement and clicks and convert them in to working commands. Another type of keyboard is the virtual keyboard this remov ...
... that the differences between the various systems with different data models can be big and substantial. Second is the common theoretical framework. Although there is no standard object-oriented model, most object-oriented database systems that are operational or under development today share a set of fundamental object-oriented concepts. Therefore the implementation issues in OODBMSs that arise due to these concepts are universal. The third characteristic is that of experimental activity. Plenty of prototypes have been implemented and some ! of them became commercial products. There is really a need for applications to handle very complex data and that ...
... of computer services. A person is guilty of the computer crime of interruption of computer services when he, without authorization, intentionally or recklessly disrupts or degrades or causes the disruption or degradation of computer services or denies or causes the denial of computer services to an authorized user of a computer system. (e) Misuse of computer system information. A person is guilty of the computer crime of misuse of computer system information when: (1) As a result of his accessing or causing to be accessed a computer system, he intentionally makes or causes to be made an unauthorized display, use, disclosure or copy, in any form, of data residin ...
... use computers for inventory and taking care of money also. Before long everyone will have a computer at home. The Internet is a big part of our lives today. It is being used everywhere and every way. The Internet was first originally used in 1969 for military purposes but look around today almost every home that has a computer has the Internet. The Internet has came a long way. Everyone has the Internet or has some access to the Internet some how. It serves for many purposes one being for business. Another may be just for enjoyment. The Internet allows people to communicate together at high speeds with their computers. People can go onto chat services and talk t ...
... in a lost jungle world. Other technological enhancements include realistic water and realistic interaction between. For instance, if you throw a barrel into a pond, it will float and bob. Throw another barrel at that one, and they will react realistically based on the momentum of the projectile. Throw in a rock, and it will sink. Trespasser also features some interesting sound technology and light sourcing techniques to add to the realistic environment. Working with the realistic physics is a real time sound system based on your character's actual manipulation of the environment. Sounds are generated based on composition, structure, and velocity of two objects c ...
... becomes a larger and more prevalent issue as there is more value to criminally gain and the stakes raise in the hacker’s ego game. Only seventy five computer crime prosecutions were reported in the United States in 1986, according to the National Center for Computer Crime Data in Santa Cruz, Calif. By 1989, that number jumped to 500 prosecutions. that year cost businesses and banks - and, ultimately, consumers - about $500 million. "As the use of computers has increased, so has their criminal misuse" (Bowers 54:g13). Computers are used to obtain credit card numbers, which are then used to order thousands of dollars worth of whatever the hackers want. "In ...
... with many university sites on it. Therefore, it was broken into two parts: MILNET, which had all the military sites, and ARPANET, which had all the nonmilitary sites. "The two networks remained connected, however, thanks to a technical scheme called IP (Internet Protocol), which enabled traffic to be routed from one net to another as needed. All the networks connected by IP in the Internet speak IP, so they can all exchange messages." (Levine 12) Even though there were only two networks at that time, IP was made to allow thousands of networks. The IP is designed so that every computer on an IP network is compatible. That means any machine can communicate with a ...
