The first electronic computer,1937-1942
The first electronic computer was built in the USA by John Atanasoff ( at Iowa University);
Between 1937 and 1942 - together with his student Clifford Berry - he built the ABC (Atanasoff-Berry Computer ).
In 1943 in England, under the guidance of Alan Turing, the "Colossus" was realized. -
The "COLOSSO" was realized
In 1943 in England, under the guidance of Alan Turing, the "Colossus" was realized. -
The ENIAC was presented
In 1946 at the University of Pennsylvania (USA) the ENIAC was presented, built under the guidance of Presper Eckert and John Mauchly. It had 17,000 valves, 70,000 resistors, 10,000 capacitors, 5,000 welds; It weighed 30 tons.
But It had a very limited memory capacity (only 20 numbers) and did not have an editable program. -
l' EDVAC, The solution to the previous problem
The solution to the previous problem was the invention of the software . Johnny von Neumann worked on a project parallel to Eniac: the EDVAC, that defined the architecture of modern computers consisting of three separate units:
1-An "electronic memory";
2-A "control unit";
3-A "calculation unit” -
Remington Rand built the UNIVAC.
In 1951, Remington Rand built the UNIVAC I used to process the data of the American census of that year. -
IBM get in the computer sector.
In 1952, IBM entered the computer sector: It launched the 701: it cost $ 800,000 and only 19 of them were built; then The 650 model was built,: it cost $ 200,000 and 2,000 were sold -
IBM introduced the "Compatible Time Sharing System"
In 1961 he introduced the "Compatible Time Sharing System" 7090/94 series: in this way, the same computer (mainframe) could be connected to lots of terminals placed in various offices; In this way, the concept of "remote access" to a "host" computer became a reality. -
Ted Hoff invented the microprocessor
In 1971 Ted Hoff (Intel ) invented the microprocessor. -
Microsoft was born!!!
in 1975 Microsoft was born
thanks to the funds obtained from the realization of Basic for Altair, Bill Gates and Paul Allen founded, on 4th April 1975, the Microsoft Corporation , in Albuquerque, a few steps from MITS.
Today, Microsoft is situated in the state of Washington, where it produces operating systems and computer software for 80% of the world computers. Bill Gates is considered to be the richest man in the world today. -
Steve Jobs and Steve Wozniak designed and built the Apple 1
Apple was designed by STEVE WOZNIAK and STEVE JOBS, in their parents' garage in Menlo Park (Silicon Valley). These two young minded--people, founders of the famous "APPLE COMPUTERS" in a story that has now become legend, constituted the "primordial broth" from which, after a rapid evolutionary step, the future "age of information" will take shape. -
The first personal computer
In 1977 The personal computers of Tandy and Commodore (Commodore PET) are
producted and sold together the monitor and they required no more a connection to the television (precursors of modern compact computers, like the Apple iMac or the Apple eMac) -
The C64 is on the market!!
It was September 1982 While all over the world the Apple company was taking pride in the sales of the new Apple II models, the Commodore International put the Commodore 64 personal computer on the market. The success of the C64 was immediate: the price of the new model was halved compared to that of the competitor and the performance was better. Furthermore, the software was infinite. Within a few years the Commodore 64 entered millions of homes, establishing an incredible sales success. -
The Macintosh PLUS was born
1984 the Macintosh PLUS is a fully graphical machine, affordable as price. The monitor (strictly black and white) is integrated with the CPU, the keyboard is poor in keys, but effective to touch, like the mouse, which has only one key. The interface is simple and complete, simulating a desk, with various folders (in the form of icons)and memory devices (floppy and hard disk) -
The first LAPTOP
1985: Toshiba launched the T1100 series notebook on the European market,which took place on April 1985 (in its first year of life more than 10 thousand models were sold in Europe) , marked a turning point in the technology of laptops. -
WIRELESS FIDELITY (wi-fi)!!!!
2000
The first products 802.11b Wi-Fi certified arrived on the market and since then the wireless it has taken hold. -
INTERNET and MOBILE PHONES!!!
From 2000 to 2010 internet is everywhere through cable or wireless connection: you can access to internet from any device. The mobiles have become mini pocket computers,they are always connected to the internet and can shoot videos in real time. But the Apple Corporation makes a complete comeback over the years by making the IPhone and the IPad ,based on a touch interface of high quality and usability. -
..and in the future ??? The quantum comp
2030 They are called quantum computers and will be a technology revolution and, especially, a revolution of power and elaboration. Nothing (or almost) will be impossible for them.
The quantum computers will be the revolution of the future: Instead of the traditional bits, are coming the qubits. What’s the benefit? Instead of the only two information values of the bits, 0 and 1, the qubits (that is the quantum bits) will have the ability of assume more values than a bit.
