Computer development path
Picture 1 of The path varies from giant to compact computer
First computer system (since 1945)
In this generation (1945-1956), the giant computer was designed by Professor Mauchly and student Eckert at the University of Pennsylvania from 1943 and launched in 1946 with a volume of 20 meters, high 2, 8 meters and a few meters wide, capable of performing 5,000 operations plus a second . After a few years, computers were popular at universities, government agencies, banks and insurance companies.

More precisely, the ENIAC computer originated from the Second World War to support the calculation of the artillery units (gun angle, terrain conditions, bullets .) Besides, also There are historians who argue that computers were even earlier than ENIAC such as the German Z3, the British Colossus, or the Atanasoff-Berry Computer in Iowa State (USA). However, only the 'time' of ENIAC attracted the attention of researchers.
The second generation, from 1958 to 1964
In the late 1970s, technology began to grow and prices also dropped so many American families knew about the device.The 1981 computer was as bulky as the big ones. Wives used it to store recipes and husbands saw it as a family financial management tool. Children also do exercises on computers and play some simple games. Popular computers of that time: Commodore PET, Atari 400, Tandy Radio Shack TRS-80 and Apple II.

It was not until 1981, IBM released the first PC in a press conference at Waldorf Astoria, New York. At that time, the 21-pound computer (about 9.5 kg) sold for $ 1,565. Some of the features of the early IBM computer were 160 KB of memory, capable of connecting to TV, playing games and word processing. It can be said, it was IBM that sparked IBM's personal computer and development boom, partly to show the long strides of global computing.
3rd generation (IBM era)

Under the leadership of Don Estridege, the father of IBM computers, PCs made from 3rd party hardware and software appeared . Specifically, the microprocessor manufactured by Intel, the MS-DOS operating system is Microsoft's product. Over the next 10 years, IBM has improved its computer greatly, by raising the speed by 10 times, increasing memory by 1,000 times and storage capacity by 10 thousand times, from 160 KB to 1 , 6 GB.
1990s
Many big brands were born so computer names like Amiga, Commodore, Atari, Sinclair and Amstrad had to ' fight ' in a fierce market, forcing prices to compete. Two names that later became popular include Compaq and Dell, known as the emerging names in the Windows platform computer market .

The release of Windows 3.0 operating system and then Windows 95, Windows 98 helped Microsoft claim its name in the computer market. While Apple has had some initial success with PowerBook, Microsoft is still a hegemony in the PC market. However, it was during the heyday of this PC that the laptop currently used by humans was born.
2000 years back here
The Y2K incident (which was a computer crash that took place in the early 2000s) turned up the time format for computer systems , but the consequences were not as serious as people anticipated. This time also evaluated an equally formidable development of the Internet.

Apple launched Mac OS X operating system in 2002, followed by PowerBooks, iBooks, iMacs, Mac Minis, and MacBook Air operating systems based on this operating system have achieved great success. In addition, Windows XP operating system is also a successful software product. Referring to this decade, humanity is more and more unable to mention netbooks and more recently tablet PCs with small, portable advantages.
