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. -

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. -
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” -
In 1951, Remington Rand built the UNIVAC I used to process the data of the American census of that year.

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

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.

In 1971 Ted Hoff (Intel ) invented the microprocessor.

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. -
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.

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) -
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.

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)

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.

2000
The first products 802.11b Wi-Fi certified arrived on the market and since then the wireless it has taken hold. -
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.

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.
