Why are telecommunication devices useful as economic indicators?

Telecommunication devices allow consumers to evaluate products, compare prices, and order products. The devices allow a company to reach more customers, track sales, and see if there are times when sales are higher than usual or lower than usual.

Contribution of technology to man development?

Without technology, humans would not have evolved into what we've become. To primitive man, fire was the technology that was most important. As humans developed and learned to use tools and farm, a larger population was able to be supported. As time moved on, technologies improved,and an even larger population could be sustained. Improving on technologies as humans have evolved is the key to survival of the species.

Difference between wire telephone and electronic telephone?

because the wire telephone has wire in it

Answer 2 Well, almost all telephones used today are electronic devices, including mobile phone, wire telephone and ip telephone. Wire telephone is just a sub branch of electronic telephone.

What did Carla Cico believe about the telecom industry?

that telecom executives must learn from the mistakes of the 1990s, when too many in the industry were concerned only with short-term results. Instead, she insisted that telecom companies must plan for long-term growth.

How do I write a program that lets me convert text to Morse code on Turbo Pascal 7.0?

There may be a more efficient method (I know very little about Morse code) but since there are only 26 letters you could use a giant if-else if statement.

Is Morse code still used?

Actually, yes it is in a variety of functions and forms. Morse code is still taught in some military training and is used as a back form of long distance communication.

What did the Telecommunications Competition and Deregulation Act of 1996 do?

It eliminated monopolies in cable television and telephone companies, opening fields traditionally regulated as public utilities to competition

How can someone use your telephone number in which to call you?

When your phone number is dialed by someone; either by pulses (rotary dial), touch tones (pushbutton dial), or digital coding (cell phone); the number is captured and decoded by equipment at a central office. The decoded number is sent to call switching equipment at the appropriate central offices (and if its a long distance call to call switching equipment at the appropriate long distance call management offices) needed to connect the call through. Once connected the central office sends a 120VAC 5Hz ring signal to your phone (or if your phone is a cell phone a digital ring command), causing your phone to ring. (Note: the ring the caller hears has nothing to do with this, it is a simulated ring generated by the central office at his end.) If your phone is picked up, the ring signal is removed, the call circuit is completed at both ends, and billing (if appropriate) begins.

What is ADSL contention ratio?

ADSL Contention ratio is the ratio of potential maximum demand on actual bandwidth.

In other words if there are 50 people using the same bandwidth of a 8Mbps ADSL line then the contention ratio is 50:1.

This in turns means that the actual bandwidth that any one of those 50 users will receive is far less than the 8Mbps.

How was Morse code used in the Vietnam war?

Morse code was used by airman flying in C-47 airplanes to pick up the north vietnamese soldiers communicating between units. While they were communicating between each other our airman were picking up their Morse code signals as well. The C-47 crew also had direction finding equipment where as we could get a good radius of the enemy and once a good radius was determined we would advise the army to determine how good a target we had picked up. They would then decide what means we would use to attack. Sometimes it would be army going after them or sometimes B52's.

What is the significance of packet size in a packet switching network?

The packet size is important because the network can then allow for flow control via a pre-determined 'window'. If there is a lot of PDUs travelling, the network can slow down the flow control, and reduce the packet window - so the receiving end can keep pace with the transmission - in an attempt to avoid a slowdown in network performance. However, in some instances the packet size can be set so that it cannot be fragmented.
