Communications and History storage
The evolution of information technologies in question Major advances in communication, as the telegraph – which actually was an improvement on the electronic media age, such as drums and smoke signals, and communication via semaphores.
The first telegraph was built in 1809, but the technology matured more than half of the nineteenth century with the development of methods for real images could be transmitted electronically (1843). To lay the transatlantic cable in 1866, communication that once took weeks or months in question could be achieved minutes.
Other advances include the development of wireless communication in the 1890s, and the combination of this technology with the machine writing to create the symbol in the 20th century.
Thomas Edison was the first to propose a way to store sound information for the invention of the phonograph 1877, but in reality was the development of magnetic tape audio recording in 1926 by German inventor Fritz became a storage Pfleumer information electronically.
magnetic tape was originally used for recording. Technology has finally arrived United States after the Second World War, and engineers in early computer use for it soon. Audiotapes were used to store computer data UNIVAC in 1951.
The interesting question is how information is stored – which differs little information is stored in the base as today. If you were listening a tape in which the data stored, you will hear a series of sounds of different lengths – but composed of only two places. These are essentially "Principles" and "Zero" – the building blocks of all computer data.
Today, we are capable of storing, processing and transmitting information than ever before in history, using only two symbols! 1 0
Information Technology Since 1980
Development in the decade 1970 integrated circuits and microprocessors have been the advances that started the real revolution in computing. Before the 1970s, computers were huge, very expensive and relatively slow.
IC and microprocessors made possible the development of smaller, faster machines that were the price range of many. 'Personal computers' have been around since the 1950s (computer pioneer Edmund Berkeley published plans for a PC was called "Simon" Radio Electronics Magazine 1950 and '51).
However, the Apple II, launched in April 1977 (price: about $ 1,300) was the first modern computer with an interactive graphical interface widely available and accessible to the general public1
The other important development was in the 1990s when a little-known academic and military networks of the 1960s and early 1980s, suddenly exploded in popularity. The World Wide Web or Internet has changed the way of access to information, communication and even entertainment.
Independent devices such as telephones, televisions and cameras are becoming the most simple to incorporate all these functions. Meanwhile, the power and capacity of computers continues to increase while the cost of technology continues to decline. But in the meantime, to take advantage of technology would be a mistake.
