On March 10, 1876, Alexander Graham Bell first transmitted speech electrically with an order to his assistant Thomas A. Watson. Since then, the telephone -- or rather the telephone system -- has revolutionized the way we live, socialize and do business, but its ultimate potential was less than apparent to 19th century society.

Alexander Graham Bell’s first telephone, the “Gallows Frame”, through which speech sounds were first transmitted electrically on June 3rd, 1875.

Digital wireless and cellular roots go back to the 1940s when commercial mobile telephony began. Compared with the furious pace of development today, it may seem odd that mobile wireless hasn't progressed further in the last 60 years. Where's my real time video watch phone? There were many reasons for this delay but the most important ones were technology, cautiousness, and federal regulation.

Alexander Graham Bell (1847-1922) of Salem, Massachusetts, USA constructed his first experimental telephone in Boston. Thomas A Watson (1854-1934) assisted Bell in his experiments.

Thirty-five short years, and presto! the newborn art of telephony is fullgrown. Three million telephones are now scattered abroad in foreign countries, and seven millions are massed here, in the land of its birth. So entirely has the telephone outgrown the ridicule with which, as many people can well remember, it was first received, that it is now in most places taken for granted, as though it were a part of the natural phenomena of this planet. It has so marvellously extended the facilities of conversation—that "art in which a man has all mankind for competitors"—that it is now an indispensable help to whoever would live the convenient life. The disadvantage of being deaf and dumb to all absent persons, which was universal in pre-telephonic days, has now happily been overcome; and I hope that this story of how and by whom it was done will be a welcome addition to American libraries.

The internet is most commonly known as the global network of networks. Connecting computers from Los Angeles to Washington, D.C. to Rome to Tokyo has been the true and best way to improve communication across the nation. The internet not only connections different types of computers, but improves both direction and indirect communication. With the internet, people are now able to use communication as a new way to live, act and communicate.

Old phones are more popular than ever and many styles have been replicated by major retailers. But, most of these replications can't match the beauty and ruggedness of an antique phone. What's more, antique phones are much more reliable than today's replicas.

Computer once meant a person who did computations, but now the term almost universally refers to automated electronic machinery. The first section of this article focuses on modern digital electronic computers and their design, constituent parts, and applications.

The development of fully electronic computers to replace mechanical calculators began during World War II with development at the University of Pennsylvania of the ENIAC processor, followed later by the EDVAC. Work on the project began in 1943 and went into service in 1946 to build an electronic computer able to do ballistics and atomic energy calculations.

The term ‘computer generation’ is often used in relation to the hardware of computers. Each phase of computer development is known as a separate generation of computers. Each phase of development is characterised by the type of switching circuits it utilized.Most computers today use the idea of ‘stored program computer’, proposed by Dr. John Von Neumann in 1945.
