Microwaves themselves were not invented; they are a kind of electromagnetic radiation, like light or radio waves. Percy Spencer invented the microwave oven while working for Raytheon.

History of telecommunication\n\nThe history of telecommunication began with the use of smoke signals and drums in Africa, the Americas and parts of Asia. In the 1790's the first fixed semaphore systems emerged in Europe however it was not until the 1830's that electrical telecommunication systems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today.\n\nEarly telecommunications\nEarly forms of telecommunication include smoke signals and drums. Drums were used by natives in Africa, New Guinea and South America whereas smoke signals were used by natives in North America and China. Contrary to what one might think, these systems were often used to do more than merely announce the presence of a camp.[1][2]\n\nIn 1792, a French engineer, Claude Chappe built the first visual telegraphy (or semaphore) system between Lille and Paris. This was followed by a line from Strasbourg to Paris. In 1794, a Swedish engineer, Abraham Edelcrantz built a quite different system from Stockholm to Drottningholm. As opposed to Chappe's system which involved pulleys rotating beams of wood, Edelcrantz's system relied only upon shutters and was therefore faster.[3] However semaphore as a communication system suffered from the need for skilled operators and expensive towers often at intervals of only ten to thirty kilometres (six to nineteen miles). As a result, the last commercial line was abandoned in 1880\n\nTelegraph and telephone\nThe first commercial electrical telegraph was constructed by Sir Charles Wheatstone and Sir William Fothergill Cooke. It used the deflection of needles to represent messages and started operating over twenty-one kilometres (thirteen miles) of the Great Western Railway on 9 April 1839. Both Wheatstone and Cooke viewed their device as "an improvement to the [existing] electromagnetic telegraph" not as a new device.\n\nOn the other side of the Atlantic Ocean, Samuel Morse independently developed a version of the electrical telegraph that he unsuccessfully demonstrated on 2 September 1837. Soon after he was joined by Alfred Vail who developed the register — a telegraph terminal that integrated a logging device for recording messages to paper tape. This was demonstrated successfully over three miles (five kilometres) on 6 January 1838 and eventually over forty miles (sixty-four kilometres) between Washington, DC and Baltimore on 24 May 1844. The patented invention proved lucrative and by 1851 telegraph lines in the United States spanned over 20,000 miles (32,000 kilometres).[5]\n\nThe first successful transatlantic telegraph cable was completed on 27 July 1866, allowing transatlantic telecommunication for the first time. Earlier transatlantic cables installed in 1857 and 1858 only operated for a few days or weeks before they failed.[6]\n\nThe conventional telephone was invented by Alexander Bell in 1876. Although in 1849 Antonio Meucci invented a device that allowed the electrical transmission of voice over a line. Meucci's device depended upon the electrophonic effect and was of little practical value because it required users to place the receiver in their mouth to “hear” what was being said.[7]\n\nThe first commercial telephone services were set-up in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven and London. Bell held patents needed for such services in both countries. The technology grew quickly from this point, with inter-city lines being built and telephone exchanges in every major city of the United States by the mid-1880's.[8][9] Despite this, transatlantic voice communication remained impossible for customers until January 7, 1927 when a connection was established using radio. However no cable connection existed until TAT-1 was inaugurated on September 25, 1956 providing 36 telephone circuits\n\nRadio and television\nIn 1832, James Lindsay gave a classroom

Mobile what? Phones I assume? Yes, they are WONDERFUL. I'm always in touch. Sometimes, I call my husband when he's in another part of our house. LOL. Sad but true...

Here is some information from wiki about security:\n\nEarly mobile phones did not have much security designed in. Some problems with these models were "cloning", a variant of identity theft, and "scanning" whereby third parties in the local area could intercept and eavesdrop in on calls. Analogue phones could also be listened to on some radio scanners.\n\nAlthough more recent digital systems (such as GSM) have attempted to address these fundamental issues, security problems continue to persist. Vulnerabilities (such as SMS spoofing) have been found in many current protocols that continue to allow the possibility of eavesdropping or cloning.

Michael Farady of England created electricity through magnets. And people before him knew about electricity for long time, so its difficult to answer who invented it.

Tomlinson invented email in 1972.\n\nDigital modems developed from the need to transmit data for North American air defense during the 1950s. Modems were used to communicate data over the public switched telephone network or PSTN. Analog telephone circuits can only transmit signals that are within the frequency range of voice communication. A modem sends and recieves data between two computers. Modem stands for modulate/demodulate.\n\nIn 1962, the first commercial modem was manufactured - the Bell 103 by AT&T. The Bell 103 was also the first modem with full-duplex transmission, frequency-shift keying or FSK, and had a speed of 300 bits per second or 300 bauds.\n\nThe 56K modem was invented by Dr. Brent Townshend in 1996.\n\nHistory of Modems\nRobert Lucky invented the automatic adaptive equalizer in 1965 at Bell Laboratories.\n\nThe Man behind the Modems\nBrent Townshend, the man who dreamed up the idea for 56K bit/sec modems.\n\nDeveloper receives patent for PCM modems\nBrent Townshend, the Quebec-based developer who worked on several core concepts for pulse-code modulated (PCM) modems, received several U.S. patents for that technology.

tierrecarter, Bill Gates didn't invent the PC. IBM invented the PC, but got its OS from Microsoft (who didn't write it, they bought it from another firm, who didn't "invent" it either, as it was a clone of Digital Research's CP/M).\n\nSince Charles Babbage has already been mentioned, I'd like to drop a word in for Alan Turing, whose theroies are essential for modern computing, or Tommy Flowers, who used Turing's theories to produce Colossus, the first digital, programmable, electronic computer.

aryabhatta of india,he also discoved the decimal system-he was a great scientist of his time,most others would say arabs,but they don't know thay arysbhatta taught them.u know that there r 2 numeral systems-roman numerals and arab numerals but u would be surprised that it is actually india who invented the arab system,arabs r given the credit because they taught all our information to europe but said that they invented this system.

The transistor was invented by Julius Edgar Lilienfeld, who was not a Nobel Prize winner.\n\nThe integrated circuit was first created by two scientists working independently: Jack Kilby and Robert Noyce. Jack Kilby co-won the Nobel Prize in 2000, but Robert Noyce has not as of yet won it.\n\nNote to 07_Shelby_GT500: \nWilliam Shockley, John Bardeen and Walter Brattain of Bell labs built the first practical transistor, but they did not invent it.

Here is a transcript of a really interesting discussion about this from an NPR broadcast.  It seems that Alexander Graham Bell, the inventor of the telephone, wanted us to say "Ahoy".

Alexander Graham Bell is generally credited for inventing or at least developing on a grand scale, the tetrahedral kite.  He actually hoped it would be the basis for making an airplane.  He made some great, giant kites but never made a practical airplane.  Bell was much more famous for inventing the telephone.
