4, logical judgment ability
The main signs of computer development:
1, the 20th century 40-50 years, is the 20th century 40-50 years, is the first generation of vacuum tube computer. Symbol: On February 14, 1946, the first electronic computer named ENIAC was born at the University of Pennsylvania.
2, transistor digital computer: in the 1960s to 1970s, the second generation of computers, Minicomputer stage
Logo: In 1954, the United States Bell Laboratories successfully developed the first computer using transistor lines, named " dike (TRADIC), which has 800 transistors.
3, integrated circuit digital computer: the 20th century 70-80 years, microcomputer stage.
In 1958, Jack Kilby, an engineer at Texas Instruments, invented the integrated circuit (IC), which combines three electronic components onto a small piece of silicon.
4, large-scale integrated circuit digital computer: client server, that is, c\/s stage (client\/server stage)
Mark: The fourth generation computer refers to the computer made of large-scale integrated circuits (LSI) and very large scale integrated circuits (VLSI) as the main electronic devices since 1970
5, computing the Internet stage, also known as the Internet, the Internet, the Internet stage
Logo: The Internet began in 1969 as a result of the US military's ARPA (ARPA Network), Under the agreement established by the Defense Research Projects Agency (DARPA), UCLA(University of California, Los Angeles) and Stanford University in the Southwest of the United States will be selected Four major computers from ResearchInstitute(Stanford University ResearchInstitute), UCSB(Universityof California), and UniversityofUtah(UniversityofUtah) are connected.
6, the cloud computing era, since 2008, the cloud computing era. Cloud Computing seen as' revolutionary computing model '
Logo: In 1983, Sun Microsystems proposed \"The Network is the Computer\
