A brief history of computing – How do you know?
The computer is a machine similar to a television way, but much more advanced than television. In fact, it is quite impossible that a person does not know anything about computers at the age of technology. Usually there is at least one computer at home for each family.
It is true that most people are aware of the importance and benefits of major equipment And know how to make the best use of their computers in their lives. However, they are clear about the history of computing?
Beginning with a great big way as a house, computers today have been developed to be as small and multifunctional as possible to be practical for people to use. During this evolution, equipment can be classified into five generations, in different periods of development.
First Generation (1945-1959) vacuum tubes
The relays have been replaced by vacuum tubes that has no moving parts so quickly, after the two hybrids are constructed. Electronic equipment was first the Colossus (1943 – but not publicly acknowledged) and ENIAC (1946), which contained 18,000 vacuum tubes and 1,500 relays. Also Notable UNIVAC was the first commercially available computer .
Second generation (1960-1965) Transistors
Vacuum tubes replaced by transistors (invented at Bell Labs in 1948). Programming Languages advanced developed, FORTRAN and COBOL, and others. The transistors were much smaller and less expensive to manufacture and more reliable than the valves.
Third generation (1965-1971) Integrated Circuits
machine speeds increased from microsecond to picosecond (trillionth) range. Terminals replaced punch cards for data entry. This period saw the emergence of operating systems and mass production of circuits. IBM introduces family compatible computer
Fourth Generation (1973 -) VLSI – Very Large Scale Integration
Supports thousands of transistors to be integrated on a chip leading to a one chip microprocessor chip. This reduces the price of personal computer mainframes.
The 1990s saw progress the fourth generation of ULSI (Ultra Large Scale Integration) with millions of transistors per chip. In 1965, Gordon Moore of Intel predicted that "the number of transistors in an integrated circuit will double every 18 months. "
Fifth Generation (1985 -) Parallel Processing and Networking
Another generation discussed. How many high-end machines (eg web servers) may have multiple processors and interconnectivity between computers, networks!
The evolution of computers also symbolizes the development of technology. Needless to say, the most advanced society, progress will be made for computers.
