... 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 wi ...

... of speakers. Reproduction of higher frequency sounds (i.e. violin, flute) as well as lower frequency sounds (bass violin, tuba) require more power to be heard at the same level as a midrange sound (voice, trumpet). The internal amplifier in the head unit must be able to generate enough wattage for the SPL (sound pressure level) of the higher frequencies to be heard clear in a space the size of the AEROSTAR. Pre-amp Out RCA Jacks To allow for low-level amplification without using an in-line power reducer, the head unit will require low level pre-amplification output jacks. Head units ordinarily come with either front and rear, or just rear RCA jacks. T ...

... in 1985, came up with the first glove in February 1986. The glove is made of thin Lycra and is fitted with 15 sensors that monitor finger flexion, extension, hand position and orientation. Connected to a computer through fiber optic cables. Sensor inputs enable the computer to generate an on screen image of the hand that follows the operator's hand movements. The glove also has miniature vibrators in the finger tips to provide feedback to the operator from grasped virtual objects. Therefore, driven by the proper software, the system allows the rator to interact by grabbing and moving a virtual object within a simulated room, while experiencing the "feel" of the ...

... hacker is. The connotation of the word 'hacker' is a person that does mischief to computer systems, like computer viruses and cybercrimes. "There is no single widely-used definition of computer-related crime, [so] computer network users and law enforcement officials must distinguish between illegal or deliberate network abuse versus behavior that is merely annoying. Legal systems everywhere are busily studying ways of dealing with crimes and criminals on the Internet" (Voss, 1996, p. 2). There are ultimately three different views on the hacker controversy. The first is that hacking or any intrusion on a computer is just like trespassing. Any electric mediu ...

With these technological advances, systems will be faster, more powerful, and capable of doing more complicated tasks. As more people with different interests, thoughts, and ideas get involved with the internet, there will be more information available (Elmer-Dewitt 64). As the number of internet users increases, the prices will gradually decrease on internet software and organizations (Peterson 358).
