http://www.xn--y3h.com ☎ - The telephone (from the Greek: τῆλε, tēle, "far" and φωνή, phōnē, "voice"), commonly referred to as a phone, is a 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 one another. It is one of the most common household appliances in the developed world, and has long been considered indispensable to business, industry and government. The word "telephone" has been adapted to many languages and is widely recognized around the world. 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) 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. The keypad may be in the handset or in a separate part. A landline telephone is connected by a wire 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. The microphone converts the sound waves to electrical signals, which are sent through the telephone network to the other phone, where they are converted back to sound waves by the earphone in the other phone's handset. Telephones are a duplex communications medium, meaning they allow the people on both ends to talk at once. The telephone network, consisting of a worldwide net of telephone lines, fiberoptic cables, microwave transmission, cellular networks, communications satellites, and undersea telephone cables connected by switching centers, allows any telephone in the world to communicate with any other. Each telephone line has an identifying number called its telephone number. In order to initiate a telephone call, a conversation with another telephone, the user enters the other telephone's number into a numeric keypad on his phone. Graphic symbols used to designate telephone service or phone-related information in print, signage, and other media include ℡(U+2121), ☎(U+260E), ☏(U+260F), and ✆(U+2706). en-us Wed, 08 Feb 2012 22:29:16 CST Wed, 08 Feb 2012 22:29:16 CST http://www.xn--y3h.com/ ☎ - The telephone (from the Greek: τῆλε, tēle, "far" and φωνή, phōnē, "voice"), commonly referred to as a phone, is a telecommunications device that transmits and receives sound, most commonly the human voice.
