The telephone (from the Greek: τῆλε, tēle,"far" and φωνή, phōnē, "voice"), often colloquially referred to as a phone, is telecommunications device that transmits and receives sound, most commonly the human voice. Telephones are a point-to-point communication system whose most basic function is to allow two people separated by large distances to talk to each other. It is one of the most common appliances in the developed world, and has long been
Indispensible to businesses, households and
A landline telephone is connected by a pair of wires to the telephone network, while a mobile phone or cell phone is portable and communicates with the telephone network by radio. A cordless telephone has a portable handset which communicates by radio with a base station connected by wire to the telephone network, and can only be used within a limited range of the base station.
All telephones have a microphone to speak into, an earphone which reproduces the voice of the other person, a ringer which makes a sound to alert the owner when a call is coming in, and a keypad (or in older phones a telephone dial or no manual device) to enter the telephone number of the telephone being called. The microphone and earphone are usually built into a handset which is held up to the face to talk.
An undisputed fact is that Alexander Graham Bell was the first to be awarded a patent for the electric telephone by the United States Patent and Trademark Office (USPTO) in March 1876. That first patent by Bell was the master patent of the telephone, from which all other patents for electric telephone devices and features flowed.
The telephone has made communication more efficient and faster since it was first developed. There is no doubt that it has made a dramatic impact on writing and teaching.
The telephone has transformed societies social behavior by changing the way we communicate with each other. The telephone has fostered a whole host of new inventions, both the cellular phone and the internet are a result of the telephone system
"The human voice carries too far as it is.. and now you fellows come along and seek to complicate matters...” “MARK TWAIN “
Facsimile comes from the Latin word Fac simile, which translates to make similar. Traditional Facsimile systems are unique as They communicate image Information, rather than audio or data.
Edward Davy invented the first practical facsimile machine in 1837, but abandoned the invention shortly thereafter. Alexander Bain, a Scottish clockmaker, revived the concept in 1846.
* Facsimile technology has been designed to transmit documents like letter, an invoice, a blue print, a photograph.
* Numerous sales oriented enterprises now rely heavily on fax broad cast systems, in place of more traditional direct mail or other forms of mail.
* Fax Over IP(FOIP) can transmit and receive pre digitized documents at near real time speed using TTU.T.recommendations T.38 to send digitized images over an IP network.
A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem.
* Most traditional communications media including telephone, music, film, and television are reshaped or redefined by the Internet, giving birth to new services such as Voice over Internet Protocol (VoIP) and IPTV.
* Newspaper, book and other print publishing are adapting to Web site technology, or are reshaped into blogging and web feeds
*The Internet has enabled or accelerated new forms of human interactions through instant messaging, Internet forums, and social networking.
*Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.
Wi-Fi ( /ˈwaɪfaɪ/ is a branded standard for wirelessly electronic devices. A Wi-Fi device, such as a personal computer, video game console, Smartphone, or digital audio player can connect to the Internet via a wireless network access point. An access point (or hotspot) has a range of about 20 meters (65 feet) indoors and a greater range outdoors. Multiple overlapping access points can cover large areas.
Electronic mail, commonly called email or e-mail, is a method of exchanging digital messages from an author to one or more recipients. Modern email operates across the Internet or other computer networks. Today\'s email systems are based on a store-and- forward model. Email servers accept, forward, deliver and store messages. Neither the users nor their computers are required to be online simultaneously; they need connect only briefly, typically to an email server, for as long as it takes to send or receive messages.

* It is virtually universal, having found its way in to wide spread consumer use through on line information service, connected via the internet and mail gate ways, which serve as protocol converters.
Radio is the transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information is carried by systematically changing (modulating) some property of the radiated waves, such as amplitude, frequency, phase, or pulse width.
* Today, radio takes many forms, including wireless networks and mobile communications of all types, as well as radio broadcasting
* Commercial radio broadcasts include not only news and music, but dramas, comedies, variety shows, and many other forms of entertainment
* TETRA, Terrestrial Trunked Radio is a digital cell phone system for military, police and ambulances. Commercial services such as XM, World Space and Sirius offer encrypted digital Satellite radio.
