- 2931: Communication Technology
- ... opportunities in that line of work. You could be anything from a radio announcer to a store clerk in an electronics store. My dad worked for Bell Canada for twenty years and they were never short on work. As long as people want to communicate there will be jobs in audio and video systems. Jobs like radio programmers, D.J.'s, audio and video mechanics, splicers, telephone operators, will always be around. There is a unlimited amount of jobs in the audio and video field. Getting you degree is not that hard either. You can get it at home or through a short course at almost any college. I think that out of all the types of communication technology, audio and video systems, supply the most jobs.
- 2932: Computer Networking
- ... connected to this network and how many guest computers might come on at one time is the question. An example of a guest computer is if someone brought a laptop and connected it for a short while to download or access data. To find the answer to the question, simply count the desktop computers that will be connected and how many guest computers you expect to be connected at one time ... expect to be connected at one time. So, the equation is: x+y+1. The one added on the end of the equation is another guest file just to make sure you don't fall short. So, this tells you how many files you need to create. The guest files will all be generically named so that all guests have the same access privileges, and all the permanent computers will have ...

Now you will probably ask, If there really is an addiction, what are the symptoms and is help available? The list of Internet Addiction symptoms is long. Most Researchers in this area stated that any ...

- ... L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. “ The danger of the information age is that while in the short run it may be cheaper to replace workers with technology, in the long run it is potentially self-destructive because there will not be enough purchasing power to grow the economy,” M. B. Zuckerman. My ... of our country's political process, in a technologically advanced world. Voting & Poisoned Political Process in The U.S. The advance of mass communication is natural in a technologically advanced society. In our country's short history, we have seen the development of the printing press, the radio, the television, and now the Internet; all of these, able to reach millions of people. Equally natural, is the poisoning and corruption of ...
- 2935: Radio: A Form of Communication
- ... carrier is radiated in the form of radio waves. In early radiotelegraph communications the transmitter was keyed on and off in a coded fashion using a telegraph key or switch. The intelligence was transmitted by short and long bursts of radio waves that represented letters of the alphabet by the Morse code's dots and dashes. This system, also known as interrupted continuous wave (ICW) or, simply, continuous wave (CW), is ... no useful information. Therefore, the only part that needs to be transmitted is one of the sidebands. A system designed to do this is called a single sideband suppressed carrier (abbreviated SSBSC, or SSB for short). This is an important system because it requires only half of the bandwidth needed for ordinary AM, thus allowing more channels to be assigned in any given portion of the frequency spectrum. Also, because of ...

- 2937: The Necessity Of Computer Security
- ... Each system is thought to encrypt a message so inscrutably that the step-by-step mathematical algorithms can be made public without compromising security. The single key system, named the Data Encryption Standard - DES for short - was designed in 1977 as the official method for protecting unclassified computer data in agencies of the American Federal government. Its evolution began in 1973 when the US National Bureau of Standards, responding to public ... block are scrambled no fewer than 16 times, resulting in eight characters of ciphertext. As good as the DES is, obsolescence will almost certainly overtake it. The life span of encryption systems tends to be short; the older and more widely used a cipher is, the higher the potential payoff if it is cracked, and the greater the likelihood that someone has succeeded. An entirely different approach to encryption, called the ...

- 2939: Telecommunications Device for the Deaf (TDD)
- ... TDD) In 1963, Robert Weitbrecht developed a large acoustic coupler. This device has helped with breaking down the communication barrier between the Hearing and Deaf communities. This device today is called the TTY, which is short for Teletypewriter. Today, most people who use these machines call them TDD, which is short for Telecommunications Device for the Deaf. TTY and TDD are names that are interchangeably used. This is a picture of what the typical TDD machine looks like today. The TDD machine operates much like an ...

- ... a signal within a matter of a second they can tell whether a collision has occurred because they do not receive their own transmission.
