The Telephone – A Brief History

Written by Jason Morris

Duringrepparttar 1870’s, two well known inventors both independently designed devices that could transmit sound along electrical cables. Those inventors were Alexander Graham Bell and Elisha Gray. Both devices were registered atrepparttar 147333 patent office within hours of each other. There followed a bitter legal battle overrepparttar 147334 invention ofrepparttar 147335 telephone, which Bell subsequently won.

The telegraph and telephone are very similar in concept, and it was through Bell’s attempts to improverepparttar 147336 telegraph that he found success withrepparttar 147337 telephone.

The telegraph had been a highly successful communication system for about 30 years before Bell began experimenting. The main problem withrepparttar 147338 telegraph was that it used Morse code, and was limited to sending and receiving one message at a time. Bell had a good understanding aboutrepparttar 147339 nature of sound and music. This enabled him to perceiverepparttar 147340 possibility of transmitting more than one message alongrepparttar 147341 same wire at one time. Bell’s idea was not new, others before him had envisaged a multiple telegraph. Bell offered his own solution,repparttar 147342 “Harmonic Telegraph”. This was based onrepparttar 147343 principal that musical notes could be sent simultaneously downrepparttar 147344 same wire, if those notes differed in pitch.

Byrepparttar 147345 latter part of 1874 Bell’s experiment had progressed enough for him to inform close family members aboutrepparttar 147346 possibility of a multiple telegraph. Bell’s future father in law, attorney Gardiner Green Hubbard sawrepparttar 147347 opportunity to breakrepparttar 147348 monopoly exerted byrepparttar 147349 Western Union Telegraph Company. He gave Bellrepparttar 147350 financial backing required for him to carry on his work developingrepparttar 147351 multiple telegraph. However Bell failed to mention that he and his accomplice, another brilliant young electrician Thomas Watson, were developing an idea which occurred to him duringrepparttar 147352 summer. This idea was to create a device that could transmitrepparttar 147353 human voice electrically.

Bell and Watson continued to work onrepparttar 147354 harmonic telegraph atrepparttar 147355 insistence of Hubbard and a few other financial backers. During March 1875 Bell met with a man called Joseph Henry withoutrepparttar 147356 knowledge of Hubbard. Joseph Henry wasrepparttar 147357 respected director ofrepparttar 147358 Smithsonian Institution. He listened closely to Bell’s ideas and offered words of encouragement. Both Bell and Watson were spurred on by Henry’s opinions and continued their work with even greater enthusiasm and determination. By June 1875 they realised their goal of creating a device that could transmit speech electrically would soon be realised. Their experiments had proven different tones would varyrepparttar 147359 strength of an electric current in a wire.

Now all they had to do was build a device with a suitable membrane capable of turning those tones into varying electronic currents and a receiver to reproducerepparttar 147360 variations and turn them back into audible format atrepparttar 147361 other end. In early June, Bell discovered that while working on his harmonic telegraph, he could hear a sound overrepparttar 147362 wire. It wasrepparttar 147363 sound of a twanging clock spring. It was on March 10th 1876 that Bell was to finally realiserepparttar 147364 success and communications potential of his new device. The possibilities of being able to talk down an electrical wire far outweighed those of a modified telegraph system, which was essentially based on just dots and dashes.

According to Bell’s notebook entry for that date, he describes his most successful experiment using his new piece of equipment,repparttar 147365 telephone. Bell spoke to his assistant Watson, who was inrepparttar 147366 next room, throughrepparttar 147367 instrument and said “Mr Watson, come here, I want to speak to you”.

Alexander Graham Bell was born on 3rd March 1847 in Edinburgh, Scotland. His family were leading authorities in elocution and speech correction. He was groomed and educated to follow a career inrepparttar 147368 same speciality. Byrepparttar 147369 age of just 29 in 1876 he had invented and patentedrepparttar 147370 telephone. His thorough knowledge of sound and acoustics helped immensely duringrepparttar 147371 development of his telephone, and gave himrepparttar 147372 edge over others working on similar projects at that time. Bell was an intellectual of quality rarely found since his death. He was a man always striving for success and searching for new ideas to nurture and develop.

Voice over IP (VoIP) Features

Written by Jason Morris

Because with VOIP you can make calls from anywhere you have access to a broadband connection, users can take their IP phones or ATA’s with them on trips and still have access to what is essentially their home phone.

Some people use a softphone to access their VOIP service. A softphone is a specially developed software application that loadsrepparttar VOIP service onto your desktop computer or laptop. Some even have an interface onrepparttar 147332 screen that looks like a traditional phone. These softphone applications allow you to place VOIP calls from your laptop; anywhere inrepparttar 147333 world you have access to a broadband connection.

Most traditional phone companies charge you for extra features that are added to your account. With VOIP service providers these usually come as standard. Features such as:

1. Caller ID

2. Call Waiting

3. Call Transfer

4. Repeat Dialling

5. Return Call

6. Three-Way Dialling

Some VOIP service providers also offer advanced call filtering features. These additional features allow you to decide how calls to a specific number are handled by using caller ID information. They allow you to:

1. Forwardrepparttar 147334 call to a particular number

2. Sendrepparttar 147335 call directly to voicemail

3. Giverepparttar 147336 caller a busy signal
